Parameter Name/Description Default and Range

SMART RECOVERY Transitions the conditioned space from one programmable

temperature period to the next with 1F increments of the heating setpoint or with 1F

decrements of the cooling setpoint, so that by the time the next period starts, the

setpoints are at the desired temperature. The purpose of the gradual transition is to use

less energy by preventing staging up (because of a higher demand) to higher stages. The

transitions occur in a linear fashion over the smart recovery time period.

If you start a temporary hold in the middle of a smart recovery, the setpoints of the

temporary hold are used.

If a temporary hold is already active during the time that smart recovery would have

been started, a smart recovery does not start.

If the temporary hold ends in the middle of what would have been a smart recovery,

the smart recovery starts where it would have been in the linear progression at the

same time as when the temporary hold was not active.

NO, 30, 60, 90 MIN

FAN ON WITH W Supplies a fan output demand as soon as a W1 or W2 output

demand is active.

YES

YES/NO

REVERSING VALVE Defines whether the ON state of the reversing valve is used for

heating or cooling when COMPRESSOR TYPE is set to HP.

When the ON state of the reversing valve is used for cooling, the signal is typically

referred to as a O.

When the ON state of the reversing valve is used for heating, the signal is typically

referred to as a B demand.

If COMPRESSOR TYPE is set to HP, the thermostat configuration may be limited for

the following:

REMOTE SENSOR Determines whether the remote sensor hardware input is:

NONE Not used

NONE or SPACE The outdoor temperature is acquired by Wi-Fi through the server,

based on the location of the mobile device used to connect the thermostat to a

router, or based on the ISP location, if a computer connects the thermostat to a

router.

OUTDOOR Senses the outdoor temperature

NOTE The outdoor temperature is not available if the thermostat is not connected to

Wi-Fi or if you do not select OUTDOOR.

AVERAGE Space temperature results from averaging the internal and the external

sensor

OCCUPANCY An external source is accessed to determine if the setpoints are

Occupied or Unoccupied. When Normally Open contacts close, the Occupied

setpoints are used.

NOTE When selected, NON-PROG is automatically set and is not displayed in the

Installer Settings until this parameter is changed.

FAULT INPUT An external source is used to detect a fault, as determined by the

attached Economizer.

SAT A sensor to provide a means of monitoring supply air temperature

ID TEMP FLT INHIBIT Allows a time delay applied to the ID TEMP fault. The range is

adjustable from 10 to 240 minutes (60 default).

NOTE Allow for recovery time when transitioning from unoccupied to occupied periods.

60 mins

10 to 240 mins

(10 min increments)

COOL LOCKOUT Delays the cooling equipment demands if the outdoor air temperature

is below the selected value. There is a SYSTEM EVENT warning if the mode and space

temperature dictate that there should be a cooling demand and the outdoor temperature

is preventing this demand.

55F

OFF

0 to 80F

(5F increments)

LOW COOL LOCKOUT (Heat pump operation only) Enables the thermostat to start all

cooling stages on a demand for cooling based on the configured value. Normal cooling

always starts with first stage compressor (Y1) and stages up to the second (Y2), when

the demand is sufficient and staging and cycle timer constraints are satisfied.

If the outdoor temperature is equal to or greater than the configured value of 80 to

110F, all stages of cooling are energized. If set to ON, all stages are energized on a call

for cooling. The outdoor temperature must also be greater than the COOL LOCKOUT

value. When a cooling cycle starts under a high cool latch, it finishes the cooling cycle on

HIGH STAGE. If the cooling equipment is energized to satisfy a dehumidify demand only

(no cooling demand), the latch is not applied.

LOW HEAT LOCKOUT (Heat Pump operation only) Enables the thermostat to start all

compressor heating stages on a demand for heating, based on the configured value.

When the COMPRESSOR TYPE is set to HP and compressor heat is requested, it always

starts with the first compressor stage (Y1) and stages up to second stage (Y1 and Y2)

when the demand is sufficient and staging and cycle timer constraints have been

satisfied.

If the outdoor temperature is equal to or less than the configured value of 20 to 50F,

both the first and second stages of the compressor are energized to satisfy all heat

pump heating demands. If set to ON, both compressors are energized on a call for

heating. The outdoor temperature must also be greater than the HP LOCKOUT value.

When a cycle starts under a high heat latch, it finishes the heating cycle on HIGH STAGE.

10, 15, 20, 25 MIN

CYCLE TIMER The maximum number of heat cycles per hour D:

2, 4, 6, 8

HUMIDIFIER The output relay enables a field-installed humidifier. The humidifier is on

if there is humidity demand and any heating equipment is on. If set to YES, the

thermostat cannot be configured for Humidi-MiZer or Dehumidification. See

HUM/DEHUM OUTPUT in this table for output relay details.

YES/NO

DEHUMIDIFIER Sets the output relay to enable a factory-installed Humidi-MiZer for

dehumidification or to use the first stage of cooling.

If HUMDIMIZER, the output relay energizes the Humidi-MiZer on the Carrier unit.

If YES, the Y1 relay is energized. A new space temp setpoint is calculated to force

cooling operation.

NOTE For details about this calculation, see HUMIDITY (page 28).

If OVRCL(2), it uses the first stage of cooling to satisfy a dehumidification demand,

but will not overcool the space by more than 2F.

If dehumidification is configured, the thermostat cannot also be configured for a

humidifier. Additional optional functions may be limited, based on the flex outputs

available.

AUX HEAT LOCKOUT The outdoor temperature value that lockouts the auxiliary heat. If

the AUX HEAT LOCKOUT temperature setting is not OFF, and the outdoor air temperature

is greater than AUX HEAT LOCKOUT value, then the Aux Heat (W1 and W2) outputs are

not energized. Once the output is energized, it remains energized until the demand

algorithm no longer requires the capacity of the auxiliary heat, regardless of the value of

the outdoor air temperature.

NOTE If the MODE is emergency heat (E-HEAT), the auxiliary heat is allowed to be

energized regardless of the outdoor temperature.

Parameter Name/Description Default and Range

HP LOCKOUT If you select OFF, the heating equipment cycle always starts with the heat

pump, regardless of the outdoor air temperature.

If you select a lockout temperature and the outdoor air temperature is less than the

selected temperature, the heating cycle is started with the AUX HEAT source.

If the outdoor air temperature is equal to or greater than the selected temperature,

the heating cycle is started with the heat pump.

If the outdoor temperature is not available, all heating cycles start with compressor

heat. Once the heat pump is energized, it remains energized until the heating

demand no longer requires heat pump heating, regardless of the outdoor air

temperature.

When the heat pump is not energized, but there is sufficient demand to request heat

pump heating, the heat pump lockout temperature is checked against the outdoor

air temperature, and if the outdoor air temperature is greater than the heat pump

lockout temperature, the heat pump is energized.

OFF

5 to 55F

(5F increments)

STAGE DELAY The minimum amount of time the current stage must be energized

before staging up to the next stage of capacity.

NOTE If the system demand is greater than 3F, then this configuration is ignored for

the current heating or cooling cycle because the staging timers are canceled to allow full

equipment capacity to meet the large demand.

10 MIN

2 MIN to 15 MIN

FORCED STAGE UP The amount of time another stage of heat or cool is enabled if the

space temperature conditions are not improving. If the time in a current demanded stage

reaches the selected forced stage-up time, the thermostat stages up to the next

available stage of capacity, even if DIFFERENTIAL demand is not met.

30 MIN

OFF

10 MIN to 120 MIN

(10 minute increments)

DIFFERENTIAL The required difference between the current space temperature and

the setpoint, before demand is initiated. This value is additive for each new stage of

equipment being demanded.

EXAMPLE A chosen DIFFERENTIAL value of 0.5F requires 0.5F difference between

setpoint and space temperature before first stage is turned on. Then, 1F of difference

between setpoint and space temperature is necessary before the second stage is turned

on.

1.0F

0.3 to 2.0F

(0.1F increments)

AIR FILTER REMINDER The number of hours before a SYSTEM EVENT reminds the

occupant to change the indoor air filter.

If set to OFF, a SYSTEM EVENT will not occur to remind the homeowner to change

the indoor air filter.

Decrements to the timer happen each hour of total equipment runtime.

Minutes are not stored in non-volatile memory, so a power reset clears out the

minutes within each hour of run time.

Once the number of hours is initially set or later changed, the filter timer must be

reset on the SETTINGS screen.

The thermostat supports the following types of constant volume units:

Standard heat/cool unit types with up to 3 stages of mechanical cooling, up to 2 stages of gas or electric

heating, and up to 4 stages for non-Carrier heat pumps

Heat pump units utilizing a reversing valve output for heating and cooling control

Carrier heat pump unit with an OEM defrost control board

NOTES

Humidification or dehumidification control strategies are available for appropriately equipped units.

The following configurations have interdependencies that may preclude the use of others:

Reversing valve

Third-stage cooling

Humidification

Dehumidification

Occupancy Output

The flex outputs, Y3, O, and W2, may be available for optional functions.

EXAMPLE In a single stage heating system, the W2 output could be used as the Occupancy output to

enable the ECON during occupied periods.

Occupancy

Configure the thermostat to operate in a programmable or non-programmable mode. Non-programmable operates

continuously in occupied mode. Programmable operates as a 7-day programmable thermostat for either 2 or 4

periods per day. You can set each period as occupied or unoccupied.

If you configure Smart Recovery for 30 to 90 minutes, the occupied start time increases up to the maximum time,

in order to bring the space to the occupied setpoints at actual occupied time.

Supply fan

Configure the supply fan for ON or AUTO, in either occupied or unoccupied mode.

ON Fan runs continuously regardless of demand

AUTO Fan cycles heat or cool demand if there is a demand for humidity or dehumidification

Thermostat 33CONNECTSTAT43 CARRIER CORPORATION 2021

Cooling

The thermostat's application and configuration determine the specific cooling sequence. It can control up to 2

stages of cooling, with an additional output for a reversing valve, for non-Carrier heat pump applications, or up to

3 stages of cooling for non-heat pump applications.

NOTE The cooling stages are controlled based on a drift algorithm and the configurable DIFFERENTIAL value

(.5F default).

The following conditions must be true for the cooling to operate:

The OAT must be above the COOL LOCKOUT (55F default), if enabled

The cooling stage 5-minute minimum off-timer has expired

The space temperature has exceeded the cooling setpoint by the DIFFERENTIAL value (.5F default)

Additional stages are added and dropped, based on demand using the DIFFERENTIAL value, STAGE DELAY timer,

and FORCED STAGE UP timer configuration values. If the LOW COOL LOCKOUT is configured for ON, or between

80 and 110F, and the OAT is equal to or greater than that value, cool stages 1 and 2 are energized on a demand

for cooling and remain on until the cooling demand is satisfied.

NOTE Once a cooling stage is energized, it remains on for a minimum of 5 minutes, regardless of demand.

Econ enable

The thermostat's application and configuration determine the specific economizer enable sequence. You can

enable an output relay in OCCUPANCY OUTPUT. The output is ON whenever the thermostat is Occupied and OFF

when Unoccupied.

NOTE The relay options may be limited by other programming options such as Humidity control, Heat Pump, etc..

The status of the economizer may be monitored using a dry contact (N.O.) on the Remote Sensor Input.

Heating

The thermostat's application and configuration determine the specific heating sequence. It can control up to 4

stages of heating when configured for non-Carrier heat pump applications, or up to 2 stages of heating for non-

heat pump applications. When applied to a Carrier commercial heat pump, HEAT TYPE must be set to GAS. HEAT

TYPE set to ELECTRIC supports the Carrier 3-stage heat operation using 2 outputs. See Outputs based on demand

and configuration (page 36).

NOTE The heating stages are controlled, based on a drift algorithm and the configurable DIFFERENTIAL value

(.5F default).

Page 28

Operating your system using the Carrier Connect Wi-Fi Thermostat

Carrier Connect Wi-Fi

Thermostat 33CONNECTSTAT43 CARRIER CORPORATION 2021

The following conditions must true for heating to operate:

The OAT must be below the HEAT LOCKOUT (55F default), if enabled

The heating stage 5-minute minimum off-timer has expired

The space temperature has exceeded the heating setpoint by the DIFFERENTIAL value (.5F default)

Additional stages are added and dropped, based on demand, using the DIFFERENTIAL value, STAGE DELAY timer,

and FORCED STAGE UP timer configuration values. If the LOW HEAT LOCKOUT is configured for ON, or between

20 and 5F, and the OAT is equal to or less than that value, heat stages 1 and 2 are energized on a demand for

heating and remain on until the heating demand is satisfied.

NOTE Once a heating stage is energized, it will remain on for a minimum of 5 minutes, regardless of demand.

Dehumidification

There is occupied and unoccupied dehumidification on units that are equipped with the Carrier Humidi-MiZer

from the factory, or by energizing the first stage of cooling and over-cooling by 2F.

The following conditions must be true for dehumidification to operate:

For the Humidi-MiZer option, DEHUMIDIFY must be set to HUMIDIMIZER

For over-cooling, DEHUMIDIFY must be set to OVRCL 2F

For non-Humidi-MiZer units, DEHUMIDIFY must be set to YES and must not have an active call for heating

or cooling

Setpoint range is 35 to 65%

Humidity must be 2% greater than the dehumidify setpoint

Dehumidification ends when DEHUMIDIFY is set to:

HUMIDIMIZER and humidity drops 3% below the dehumidify setpoint

OVRCL2 and space temperature drops below the cooling setpoint by more than 2F

YES and space temperature drops below the calculated setpoint or there is a demand for heat or cool.

NOTE For details about this calculation, see HUMIDITY (page 28).

Humidification

There is occupied and unoccupied humidification on units that are equipped with humidifiers.

The following conditions must be true for humidification to operate:

HUMIDIFIER must be set to YES

Must be in heating mode

Setpoint range is 15 to 50%

Humidity must be 3% less than the humidify setpoint

Humidification ends when the humidity rises 3% above the humidify setpoint or the heating demand is satisfied.

Filter status

FILTER STATUS is based on a supply fan runtime, which you can configure from 500 to 3000 hours. A filter status

alert displays when the filter timer exceeds the configured number of hours. Press to see message.

Holidays

There is a maximum of 24 holiday periods. You can program each holiday period based on a start and stop month

date, or day of the month and week, with duration up to 365 days. The holiday schedule uses the first unoccupied

period setpoints for temperature control.

BACnet integration

There are two points that act as gateways, allowing or prohibiting BACnet writes to configuration items (BACNET

CONFIG WRITE) and occupancy control (BACNET BMS OCC). These variables are only accessible via the local

screen.

See To configure advanced SYSTEM SETTINGS (page 14) for BACnet set-up and control.

A write to the Active Heat or Cool Setpoint (AV:409 or AV:410) places the thermostat into temporary override. This

override will remain in effect until the MAX Temperature Hold Time (AV:502) expires. Default is 2 hours.

Long-term setpoint adjustment is accomplished by writing to the baseline setpoints (AV:400- AV:403).

If cooling equipment is not available, COOL TO DEHUMIDIFY is not adjustable on the thermostat and the blue

Dehum Setpoint wheel is not adjustable.

HUMIDIFY not adjustable on the thermostat (the orange Hum Setpoint wheel is not adjustable) unless

configured to use one of the following outputs:

O/B

DEHUMIDIFY = YES When humidity is above the dehumidify target, the cooling setpoint is adjusted downward,

increasing cooling demand, according to the equations in the following table, when you select YES for

DEHUMIDIFY (not true for OVERCOOL (2) or HUMIDIMIZER selections).

Cooling Setpoint Algorithm

< = 70F Use the cooling setpoint only

70.1 - 74.9F Cooling setpoint = Cooling Setpoint (Cooling Setpoint - 70F) x (Dehumidify

Error / 10) with maximum dehumidify Error of 6% (i.e. use 6% if >6%)

> = 75 Cooling setpoint = Cooling Setpoint (Dehumidify Error / 2) with maximum

dehumidify Error of 6%

When cooling to dehumidify, the minimum ON timer increases to 5 minutes and the second stage (or greater) is

not started unless there is also a cooling demand.

OVERCOOL 2 commands the system to operate the compressor, within limits, when there is a dehumidification

demand, even if there is no cooling demand. The system may overcool up to 2F and no more, when satisfying a

dehumidification demand.

Humidi-MiZer

When configured as a HUMIDIMIZER output, and the humidity level is above the dehumidify target, 24V is output

at the selected terminal. When the humidity level is below the dehumidify target, 0 Vac is output on the selected

terminal. There is a +1/-4% hysteresis around the dehumidify target to prevent rapid on/off cycling of the selected

output.

This output may be connected to compressor outputs on commercial equipment. If the selected output is

energized without any compressors being energized, the 5-minute time guard must be enforced.

Use the following table to determine values for the terminal outputs to the equipment, when specific demands are

present.

NOTES

The value of X denotes that the setting may be Off or On, depending on the state of the FAN ON WITH W set

on advanced SYSTEM SETTINGS screen.

Recovering from a power outage

The Carrier Connect Wi-Fi Thermostat stores the following critical information in a non-volatile flash memory:

Installer settings

Owner settings

Program schedule

Software information

Dealer information

Fault and system event information

Date and time

The Carrier Connect Wi-Fi Thermostat uses a capacitor to maintain date and time for approximately 2 hours, in

order to maintain data during short power interruptions. If the power outage is longer than 2 hours, the date and

time will automatically be updated once network connection is re-established.
