Service Test
Navigation: i-Vu / Field Assistant: Properties > Control Program > Configuration > Service Configuration > Service Test
You can use Service Test to verify proper operation of cooling, heating, the fan, and the mixed air damper. We highly recommended using Service Test at initial system start-up and during troubleshooting. See Appendix C: Points/Properties for more information.
Service Test differs from normal operation as follows:
Outdoor air temperature limits for cooling and heating are ignored.
Normal fan delays (delay on) and minimum/maximum run times are ignored. A 15-second delay for electric
heat allows the fan to start operating.
Supply air temperature limits are ignored.
Alarm statuses are ignored, but all alarms and alerts are still broadcast on the network, if applicable.
You can turn Service Test on or off from an Equipment Touch device, Field Assistant, or the i-Vu application. Select Default Value of Enable to turn on and Disable to turn off. Service Test automatically disables after 1 hour.
NOTES
Service Test allows testing of each controller function.
We recommend you return every individual Service Test variable (Fan Test, Heating Test, etc.) to Disable or 0.00 after testing each function.
All outputs return to normal operation when Service Test is set to Disable.
Service Test functions
Service Test enables the test mode and stops the normal operation of the unit. Set Service Test to Enable before any other test can be performed.
Sensor Status Test - If Bypass Sensor Test is set to No, this test verifies that the SAT, RAT, and OAT sensors are all properly connected to the controller and are displaying the same temperature +/- 5 F. If this test
fails, the fan test below cannot be performed until the problem sensor is corrected. (This is a factory test that SHOULD NOT be performed on an installed unit.)
Fan Test tests the fan operation. The fan test is automatic. Set Fan Test to Enable to run the fan at the lowest
available speed, depending on your configured fan speed. The fan operates at that speed for approximately 60 seconds and then automatically increments to the next higher speed. The process repeats until it reaches the highest speed.
Fan Speed displays the actual operating speed of the fan during the test.
Cooling Test activates the units cooling. During cooling test, the appropriate cooling device is activated. If DX
cooling is configured, the supply fan output is activated and deactivated in conjunction with this test. (For 2- pipe/electric heat, the water valve output is tested during this test.)
Heating Test activates the units heating. During the heating test, the appropriate heating device is activated.
If Electric Heat is configured, the supply fan output activates and deactivates in conjunction with this test,
and if equipped with a F&B damper, the electric heat test is delayed for 30 seconds while the F&B damper moves to the full-face position. (For 2-pipe/electric heat, the electric heat output is tested during this test).

Preload OA Damper drives the mixed air damper actuator output to 7.5% open. The installer should secure
the damper shaft to the actuator with the damper in the fully closed position at this time. This provides sufficient preload on the damper seal to insure it fully closes.
Open Vent Damper 100% opens the mixed air damper to the 100% outdoor air. The output increases slowly to drive the damper to the fully open position.
Return all individual variables to Disable. Set Service Test to Disable or cycle power to the controller to return to normal operation.
Configure the Unit Vent for AppController's properties
You must configure certain points and properties. Appendix C is a complete list of all the points and properties, with descriptions, defaults, and ranges. These properties affect the unit operation and/or control. Review and understand the meaning and purpose of each property before changing it.
To start up the controller, configure your necessary points/properties in the following:
Unit Configuration (page 55)
Setpoints (page 58)
Service Configuration (page 67)
Examples of some settings that you need to configure for start-up are the Occupied and Unoccupied Heating and Cooling setpoints, found in the Setpoints section of Appendix C.
Unit Ventilator CARRIER CORPORATION 2021

The Unit Vent for AppController controls mechanical cooling and heating based on its own space temperature
input and setpoints. An optional CO2 (Indoor Air Quality) sensor mounted in the space maximizes occupant comfort
when used with the Modulating Mixed Air Damper option.
See Scheduling (page 39) for occupancy types.
The following sections describe the functionality of the Unit Vent for AppController. All points in this sequence of operation refer to the Equipment Touch, i-Vu, or Field Assistant interface.
Scheduling
Scheduling
You must configure time periods to schedule the transitions from occupied to unoccupied operation. The time
periods control the space temperature to occupied heating and cooling setpoints. The controller operates continuously in the Occupied mode until you either configure a Time Schedule or a third party control system
Enables/Disables the BAS On/Off point. You must set the local time and date for these functions to operate properly.
The controller is defaulted to control to the occupied setpoints all the time, until either a Time Schedule is configured or a third party control system Enables/Disables the BAS On/Off point. The local time and date must be set for these functions to operate properly.
The occupancy source can be changed to one of the following:
Occupancy Schedules
The controller is occupied 24/7 until you configure a time schedule using the Equipment Touch, Field
Assistant, or the i-Vu application, or until a third party control system Enables/Disables the BAS On/Off point. You can disable this by going to Configuration > Unit Configuration > Occupancy Schedules and changing the point from Enable to Disable and clicking OK.
NOTE You must Enable this point in order for the Equipment Touch, Field Assistant, or the i-Vu application to assign a time schedule to the controller.
Schedule
The unit operates according to the schedule configured and stored in the unit. The schedule is accessible in
the Equipment Touch, Field Assistant, or the i-Vu application. The daily schedule consists of a start and stop time (standard or 24 hour mode) and seven days of the week, starting with Monday and ending on Sunday.
Occupancy Input Contact (optional)
If configured for remote occupancy control, the controller uses an external dry contact closure to determine
the occupancy status of the unit. Disable the Occupancy Schedules in order to use the occupancy contact input.
NOTE Scheduling can only be controlled from one source.
Sequence of Operation
Unit Ventilator CARRIER CORPORATION 2021
for AppController v2 Installation
and Start-up Guide 40 All rights reserved
BAS (Building Automation System) On/Off
For use with a Building Automation System that supports network scheduling, you must disable the Occupancy Schedules so the BAS can control the unit through a network communication and the BAS scheduling function.
NOTE Scheduling can either be controlled from the unit or the BAS, but not both.
System Occupancy
Uses the network to obtain an occupancy status value from another controller, which is read over the network and used by this controller. Occupancy Schedules MUST be set to Disable to use this function.
NOTE Scheduling can only be controlled from one source.
Supply fan
You can configure the indoor fan to operate in any 1 of 3 Fan Modes:
Auto (default) - runs intermittently during both occupied and unoccupied periods
Continuous - runs continuously during occupied periods and intermittently during unoccupied periods
Always on - runs continuously regardless of occupancy
In the Continuous mode, the fan is turned on when one of the following is true:
It is in occupied mode, as determined by its occupancy status
There is a demand for cooling or heating in the unoccupied mode
There is a call for ventilation (IAQ override - optional)
When power is reapplied after a power outage, or when transitioning from unoccupied to occupied, you can configure a delay of 5 - 600 (default 60) seconds before starting the fan. Configure as follows:
Fan On Delay defines the delay time (0 - 30 seconds, default 30) before the fan begins to operate after heating or cooling is started and is automatically overridden if electric heat or DX cooling are active.
Fan Off Delay defines the delay time (0 - 180 seconds, default 120) the fan continues to operate after
heating or cooling stops.
The fan runs as long as cooling, heating, economizer operation, or DCV is active. If the space temperature failure alarm, condensate overflow alarm, or the test mode is active, the fan shuts down immediately, regardless of occupancy state or demand.
Automatic Fan Speed Control - The Unit Vent for AppController controls up to 3 fan speeds using a Fan Interface board or field-installed relays. The fan motor operates at the lowest speed possible to provide quiet and efficient
fan operation with the best latent capability during cooling. The motor increases speed if additional cooling or heating (except for electric heating) is required to reach the desired space temperature setpoint. The motor's
speed increases as the space temperature rises above the cooling setpoint or falls below the heating setpoint. The amount of space temperature increase above or below the setpoint that is required to increase the fan speed
is configurable. Also, the fan speed increases as the Supply Air Temperature approaches the configured minimum or maximum SAT limits if DX cooling or electric heat is active.
Unit Ventilator CARRIER CORPORATION 2021
for AppController v2 Installation
and Start-up Guide 41 All rights reserved
Configuring Automatic Fan Speed setpoints When configured for more than 1 speed, the fan speed selection is
based on Space Temperature compared to the Effective Setpoints. For example, if configured for a 3-speed fan, the fan will go to Medium speed when the Space Temp exceeds the Cool 1/ Heat 1 level. The setpoint graph
represents this as the yellow and light blue areas. The fan increases to High speed when the Space Temp exceeds Cool 2/ Heat 2 level. These are represented by the orange and dark blue areas. Speed is reduced when the Space
Temp passes the same threshold, but includes a non-adjustable Hysteresis (differential) of 0.5 F (.27 C) for both heating and cooling modes. All color bands (yellow, orange, light blue and dark blue) MUST be set to more than 0.5 F (.27 C).
Manual Fan Speed Control - When you use the controller with the optional SPT sensor, the automatic fan speed operation may be overridden from the SPT sensor (if applicable). You can select any available motor speed or automatic operation.
Unoccupied Fan Cycling - When Unoccupied Fan Cycling is set to Enable (default), the controller operates the equipments fan for 1 minute every hour during the unoccupied period. The fan operates at the lowest speed
Fan Speed Control - Electric Heat Override - When electric heat is required and active, the control continuously
monitors the supply air temperature to verify it does not rise above the configured Maximum Heating SAT Limit [90F (32.2C) default]. As the SAT approaches the limit minus 10 F (5.5 C), the fan speed increases to
ensure the SAT remains below the limit. This provides the most quiet and efficient operation by running the fan at the lowest speed possible.
Fan Speed Control - DX Cooling override - When DX (direct expansion) mechanical cooling is required and active,
the control continuously monitors the supply air temperature to maintain the SAT at or above the configured
Minimum Cooling SAT Limit [50F (10C) default] plus 5 F (2.7 C). When the SAT drops below this value, the fan speed increases to prevent the SAT from dropping further. The fan operates at the lowest speed to maximize latent capacity during cooling.
Fan Status (Option) - The optional input can be configured as either an occupancy input or a fan status input. If configured as fan status, the controller compares the status of the fan to the desired commanded state. When the
fan is commanded to run (ON), the fan status is checked and verified to match the commanded state. If the fan status is not on, then a fan status alarm is generated after 1 minute and the equipment's MAD is disabled. If the equipment has hydronic heat configured, the heating algorithm maintains the desired fan off setpoint.

Cooling
The Unit Vent for AppController operates mechanical cooling (one stage of DX, a modulating chilled water valve or
a F&B damper plus a 2-position water valve) to maintain the desired cooling setpoint. The cooling is controlled by the PI (Proportional-integral) cooling algorithm and integrated with the modulating mixed-air damper control. The
required Cooling Control Setpoint is calculated by the controller and the cooling device is controlled to maintain the Supply Air Temperature at this setpoint. This setpoint is compared to the actual supply air temperature and determines valve or damper operation and staging control for DX.
The following conditions must be true in order for the cooling algorithm to run:
Cool Enable is set to Enable
Space temperature reading is valid
Supply fan must not be in alarm
For 2-pipe systems, the water temperature is suitable for cooling
Heat mode is not active
For DX, the 5 minute compressor time-guard timer has expired
Fire/Smoke Detector (FSD) is Normal
OAT > damper setpoint plus 3 F (1.6 C)/hr and damper output > 95% for 1 minute, or, OAT is NOT
suitable for cooling, or, Damper Type is not Modulating.
OAT is greater than the Cooling Lockout Temperature
If occupied, the SPT is greater than the Occupied Cooling setpoint
If unoccupied, the SPT is greater than the Unoccupied Cooling setpoint
If all the above conditions are met, cooling is energized as required, otherwise it is disabled. If cooling is active
and the SAT approaches the minimum SAT limit, the cooling valve modulates closed. (For DX cooling, if the SAT drops below the configured minimum SAT value, the fan is indexed to a higher speed. If this is insufficient and if the SAT falls below the minimum limit minus 5 F (2.7 C), the DX cooling will be disabled.)
The configuration screens contain Min Cooling SAT and Cooling Lockout based on outdoor air temperature (OAT). Both can be adjusted to meet various specifications.
For DX cooling, after the compressor is staged off, it may be restarted again after the supply air temperature has
increased above the minimum supply air temperature limit. There is a 5 minute minimum off-time for the compressor as well as a 2 minute minimum on-time to prevent oil migration.
Modulating Chilled Water - The control can operate a modulating (0-10 Vdc or 2-10 Vdc) type, NO or NC, chilled
water valve connected to the cooling coil of the unit in order to maintain the desired cooling setpoint. The valve modulates to maintain the SAT at the calculated Cooling Control Setpoint. The control will also prevent the SAT from exceeding the Minimum Cooling SAT limit.
Face & Bypass Chilled Water - The control can operate a modulating (0-10 Vdc or 2-10 Vdc) type F&B damper and
an optional 2-position NO or NC chilled water valve to maintain the desired cooling setpoint. The damper modulates to maintain the SAT at the calculated Cooling Control Setpoint. The valve opens when cooling is
required (and the water is suitable if 2-pipe changeover). The control will prevent the SAT from exceeding the Minimum Cooling SAT limit.
Single Stage Direct Expansion (DX) - The control can operate a single stage of DX cooling in order to maintain the
desired cooling setpoint. The DX stage is controlled to prevent the SAT from exceeding the Minimum Cooling SAT minus 5 F (2.7 C) and also subject to a 2 minute minimum on-time. The compressor output is not energized
unless SAT > Minimum Cooling SAT limit plus 10 F (5.5 C). Once disabled, the compressor cannot be restarted for at least 5 minutes.

Heating
The Unit Vent for AppController operates mechanical heating (staged electric heat, a modulating hot water/steal
valve, or a F&B damper plus a 2-position heating valve, or a combination) to maintain the desired heating setpoint. The heating is controlled by the PI (Proportional-integral) heating algorithm and the heating stage
capacity algorithm for electric heat. The desired Heating Control Setpoint is calculated by the controller. This setpoint is compared to the actual supply air temperature and determines valve or damper operation and staging control for electric heat.
The following conditions must be true in order for the heating algorithm to run:
Heat Enable is set to Enable
Space temperature reading is valid
Supply Fan must not be in alarm
For 2-pipe systems, the water temperature is suitable for heating
Cool mode is not active
For electric heat, the minimum off timers have expired
Fire/Smoke Detector (FSD) is Normal
OAT is less than the heating lockout temperature
If occupied, the SPT is less than the occupied heating setpoint
If unoccupied, the SPT is less than the unoccupied heating setpoint
If all the above conditions are met, the heating outputs are energized as required, otherwise they are de- energized. If the heating is active and the SAT approaches the maximum SAT limit, the heating valve modulates
closed, or the F&B damper moves to the coil bypass position. For electric heating, if the SAT rises above the configured Maximum SAT value minus 10 F (5.5 C), the fan is indexed to a higher speed. If this is insufficient
and the SAT continues to approach the maximum limit, the EH heating stages are proportionally disabled. After the electric heater stage is turned off, it may be restarted again until after the supply air temperature falls below
the maximum supply air temperature limit. There is a minimum off-time for the electric heater stage to protect against excessive cycling.
The configuration screens contain the Max SAT parameter as well as Heating Lockout based on outdoor air temperature (OAT). Both can be adjusted to meet various specifications.
Modulating Hot Water/Steam Heating - The control can operate a modulating (0-10 Vdc or 2-10 Vdc) type, NO or NC, hot water or steam valve, connected to the heating coil of the unit and supplied by a boiler in order to
maintain the desired heating setpoint. The valve is controlled to maintain the Heating Control Setpoint during heating and will not exceed the Maximum Heating SAT limit. If the fan is off or a fan failure alarm occurs, the valve modulates to maintain the Supply Air Temperature at the configured Fan Off Value.
Face & Bypass Hot Water/Steam - The control can operate a modulating (0-10 Vdc or 2-10 Vdc) type F&B damper and an optional 2-position NO or NC heating valve in order to maintain the desired heating setpoint. The damper
modulates to maintain the SAT at the calculated Heating Control Setpoint. The valve opens when heating is required (and the water is suitable if 2-pipe changeover). The control will prevent the SAT from exceeding the Maximum Heating SAT limit.
Unit Ventilator CARRIER CORPORATION 2021
for AppController v2 Installation
and Start-up Guide 44 All rights reserved
Electric Heat - The control can operate up to 3 stages (1 stage default) of electric heat in order to maintain the
desired heating setpoint. The heat stages are controlled to maintain the Heating Control Setpoint during heating and will not exceed the Maximum Heating SAT. Stage cycling is subject to a 2 minute minimum off-time to
prevent excessive cycling (30 seconds for stage #1). The number of electric heat stages is limited so that the total number of combined fan speeds and electric heat stages equal 4.
Combination Heating - The control can operate the modulating hot water heat or the Face & Bypass Hot Water
heat (with a suitable 2-position valve plus electric heat) in order to maintain the desired heating setpoint. The non- electric heat is used to meet the heating requirements in the space when the changeover mode is heat. The
electric heater is used when the changeover mode is cool. If the fan is off and the changeover mode is heat, the non-electric heat is controlled to maintain the Supply Air Temperature at the configured Fan Off Value.
Mixed air damper (Modulating)
The Unit Vent for AppController operates a mixed air damper to maintain the desired cooling setpoint without
mechanical cooling, while also providing the required ventilation. The modulating mixed air damper is controlled by the PI (Proportional-integral) cooling algorithm and integrated with mechanical cooling while also maintaining a
minimum OA intake if the optional CO2 sensor is available. See Indoor Air Quality (page 46) for additional
information.
The desired Damper Setpoint is calculated by the controller when cooling is required. The Damper Setpoint Override Value provides the capability to maintain a user-defined fixed supply air temperature when cooling is
required and available. It will override the PI temperature control algorithm when the Damper Setpoint Override Value is not equal to 0 (and must be greater than 45F (7.2C). The Damper Setpoint is compared to the actual supply air temperature and used to determine the Mixed Air Damper position.
The following conditions must be true in order for the modulating damper (economizer) algorithm to run:
Damper Type is Modulating
Space temperature reading is valid
Supply Fan must be on and not in Alarm
OAT is valid
Heat mode is not active
Fire/Smoke Detector (FSD) is Normal
OAT is less than Damper Lockout Temperature limit
OAT is less than RAT/SPT sensor
If occupied, the SPT is greater than the Occupied Cooling setpoint
If unoccupied, the SPT is greater than the Unoccupied Cooling setpoint
If all the above conditions are met, the mixed air damper will operate as an economizer as required, otherwise it will be disabled and maintain either a closed or minimum damper position.
The configuration screens contain the Min Cooling SAT and Damper Lockout parameter based on outdoor air temperature (OAT). Both can be adjusted to meet various specifications.

Mixed air damper (2-position)
The control can operate a 2-position (0-10 Vdc or 2-10 Vdc) type minimum outdoor air damper to maintain the
desired ventilation during occupied periods. The damper output provides a 10 Vdc signal when the control is occupied or in an occupancy override mode. When the control is unoccupied or the fan is off, the damper output
will go to 0 Vdc. To control the maximum amount of outdoor air entering the unit, a mechanical actuator stop must be set.
The following conditions must be true in order for the 2-position damper algorithm to run:
Damper Type is 2-Pos
Supply Fan must be on and not in alarm
The unit is in an occupied mode
Changeover mode detection
The Unit Vent for AppController determines the changeover mode for 2-pipe heating/cooling systems. The
controller monitors a local changeover thermistor sensor or switch, dependent upon the configuration. For thermistor applications, the heat or cool mode is determined by user-configurable temperature setpoints. When
the sensed temperature exceeds the Changeover Heat Limit, the system changeover mode is set to heat. When the sensed temperature falls below the Changeover Cool Limit, the system changeover mode is set to cool. For
applications using a switch, the heat mode is determined when the input is open, while a closed switch indicates cool mode.
Additionally, an Analog Network Input point and a BACnet Analog Value input variable are also provided to allow a network-supplied analog value of the system water temperature to be used to determine the changeover mode.
The Analog Network Input point has the highest priority, followed by the BACnet AV point, then the local input if multiple inputs are supplied simultaneously.

Indoor Air Quality
If used with a modulating-type mixed air damper, the controller can provide Demand Controlled Ventilation (DCV)
to properly ventilate an occupied space. To meet ventilation requirement, the fan must be configured for the Continuous or Always On mode of operation.
Demand Control Ventilation (DCV) - If the optional CO2 sensor (or a CO2 sensor value) is available and a
modulating mixed air damper is installed, the controller will increase the minimum damper opening to outdoor air
as required by the CO2 levels within the occupied space. The control provides DCV during occupied periods. The
control monitors the CO2 level and compares it to the configured setpoints and adjusts the minimum damper
position as required. The control provides proportional ventilation to meet the requirements of ASHRAE
specifications by providing a base ventilation rate and then increasing the rate as the CO2 level increases. The
control begins to proportionally increase ventilation when the CO2 level rises above the start ventilation setpoint
and reaches the full ventilation rate when the CO2 level is at or above the maximum setpoint.
The configurable Minimum Damper Pos insures that proper base ventilation is delivered when occupants are not
present. The DCV Max Vent Damper Pos (default 60%) limits the maximum amount of outdoor air. An automatic minimum mixed air temperature override control prevents unacceptable mixed air temperatures when the outdoor
air is extremely cold. It proportionally resets the maximum amount of outdoor air used for DCV from the configured DCV Max Vent Damper Pos as the OA drops below the Minimum Cooling SAT limit and ends at the Minimum Damper Pos when the OAT reaches 10F (-12.2C).
If this additional outdoor air being introduced for ventilation causes an unacceptable drop in the supply air
temperature or could cause a potential coil freeze-up condition, then the control can be set to temper the supply air during DCV control. The control uses heating to prevent the supply air from falling below the configurable Min
DCV Override SAT setpoint, when the DCV control is active. The IAQ configurations are accessed on the Properties page > Equipment tab > Configuration.
The following conditions must be true for this algorithm to run:
Damper Control is configured for Modulating
Valid space temperature must be available
The unit is in an occupied mode
Supply Fan must be on and not in alarm
IAQ sensor value reading is greater than the DCV Start Control Setpoint
The DCV calculated damper position must be > the economizer position
The configuration screens contain the 5 adjustable setpoints:
DCV Start Control setpoint
DCV Maximum Control setpoint
Minimum Damper Position
DCV Maximum Vent Damper Position
Min SAT in DCV Override
These can be adjusted to meet various specifications.

Demand Limiting
The Unit Vent for AppController accepts 3 levels of demand limit from the network. In response to a demand limit,
the unit decreases its heating setpoint and increases its cooling setpoint to widen the range in order to immediately lower the electrical demand. You can change the responding temperature adjustment for both heating and cooling and each demand level. The response to a particular demand level may also be set to 0.
Thermostat Linkage
The controller uses one wall-mounted SPT-type sensor to control multiple units using Thermostat Linkage. A single unit is selected as a master and configured for the total number of linked units (including the master). The slave units must be sequentially addressed, below the masters address.
The master sends the setpoints, occupancy status, space temperature, and optional sensor value from the master
to the slave units. Each slave then sends its operating mode and supply air temperature. If a local sensor for
either RH or CO2 is provided, the value at the slave unit vent, rather than the value received through Thermostat
Linkage, is used.
Each slave sends its operating mode and supply air temperature. When using Thermostat Linkage, the units do
not need to be the same type or have the same coils. Each unit may be independently configured for coil types, fan operation, etc. Thermostat Linkage is designed to support a maximum of 8 units operating together, using a single SPT sensor.

Setpoints
Navigation: i-Vu / Field Assistant: Properties > Control Program > Configuration > Setpoints
Select a color band on the setpoint graph to see the current setpoints in the Heating and Cooling fields. The values in this graphic are Fahrenheit. See setpoint descriptions below.
NOTE This graphic is an example only. Your setpoints may differ.
Occupied Setpoints
The occupied setpoints described below are the setpoints under normal operating conditions. The Demand Level 13 setpoints apply if demand limiting is used.
Demand limiting is a cost-saving strategy to reduce energy consumption. The strategy expands the occupied heating and cooling setpoints when the system reaches one of 3 levels of consumption. With the expanded setpoints, the equipment
works less, thereby saving energy. By default, Demand Level 1 expands the occupied heating and cooling setpoints by 1 F ( .5C), Demand Level 2 by 2 F (1.1 C), and Demand Level 3 by 4 F (2.2 C). If the occupied heating or
cooling setpoints change, the (effective) demand level setpoints automatically change by the same amount. See Sequence of Operation (page 39) for more information.
