ComfortVu BACnet Thermostat Model Standard TB-HM (Line voltage)Carrier Proprietary and Confidential CARRIER CORPORATION 2020 Installation and Operation Guide All rights reserved 12
Freeze Protection
The Freeze protection feature will not allow the room temperature to drop below predefined cut-in temperature. Depending on which configuration the system is operating under (W/WO Heat pump), this feature will force the system to operate in heat mode and activate the fan.
This feature will take effect when the thermostat is either ON or OFF. When the room temperature rises above the predefined cut-out temperature, the thermostat will return to its previous state.
When freeze protection is activated, the display alternates between AL and room temperature.
Economizer
Economizer is used to reduce the energy consumed by the cooling systems, by using low external air temperatures to assist in the chilling process. When outdoor temperatures are lower relative to indoor (room) temperatures, the system utilizes the cool outdoor air as a free cooling source.
The outdoor temperature (Teconomizer) triggering the activation of the economizer, can be measured by the temperature sensor connected to T1,0 terminals (technician parameter P08="05") or by setting a temperature value manually through communication - AV#129 "TEconomizerEffective".
When getting the temperature through communication, terminals T1,0 can be used for any other functionality like External sensor/Soft start in heat sensor/De-icing in cool/Door switch/Key tag.
Whenever there is demand for cooling and the outdoor temperature conditions allow the operation of the economizer, it will operate together with the regular cooling system and will not replace it.
Economizer will start when, and run as long as, both of the following conditions are satisfied:
1 Teconomizer temperature < Room temperature - (Cool differential band / 2)
2 Room Temperature > Setpoint temperature
ComfortVu BACnet Thermostat Model Standard TB-HM (Line voltage)Carrier Proprietary and Confidential CARRIER CORPORATION 2020 Installation and Operation Guide All rights reserved 13
Economizer will stop when the following condition is satisfied:
Room Temperature < Setpoint temperature - (Cool differential band / 2)
Indication for the Economizer operation:
When Economizer is active, the Cool symbol will appear (or flash when active) on display and the Fan symbol will flash.
Economizer Active

General Prior to programming, make sure that Technician Settings P107, P108, and P109 are configured correctly.
Program types The thermostat can be configured to run four different types of weekly programs (set by Technician Setting P107):
7-day program with same parameters for all days.
7-day program with different parameters for each day of the week.
One schedule for the weekdays (Monday to Friday), one schedule for Saturday and another one for Sunday.
One schedule for the weekdays (Monday to Friday) and another one for Saturday and Sunday.
Daily events Each daily program can use 2 or 4 schedule events per day (set by Technician Setting P108).
There are two options for settings the schedule events (set by Technician Setting P109):
EU Type - Start time and Stop time.
US Type - Start time, setpoint temperatures, system mode and fan speed.
IMPORTANT
Parameter P107 must not be equal to 0 in order to enable weekly program capabilities.
Changing P107 to 0 will disable all program capabilities and reset programmed information.
Enabling/Temporarily Disabling/Overriding the program Activate the program
When the program is activated, a clock icon appears on the display.
If a clock icon does not appear, ensure that the set-point temperature is not 10/11C or 50/52F, press
and hold the button to activate the program.
Weekly program
ComfortVu BACnet Thermostat Model Standard TB-HM (Line voltage)Carrier Proprietary and Confidential CARRIER CORPORATION 2020 Installation and Operation Guide All rights reserved 15

5 Switch power supply off and on again for the MAC address changes to take effect.
Caution: Do not use the same MAC address for two devices on the same communication bus!
BACnet Device Instance Number
By default, the BACnet Device Instance Number is generated automatically by the thermostat (Vendor ID + MAC address). For example, Carrier Corporation vendor ID is 16, and if the MAC address is 075, the BACnet Device Instance Number is 16075.
Note: If you change the MAC address, you must cycle the thermostats power to reset the BACnet Device Instance Number.
You can override the automatically-generated BACnet Device Instance Number using the i-Vu application, an Analog Network Output microblock in a control program, or some other BACnet utility. Write the new BACnet Device Instance Number to the present_value property of Analog Value 42 (BACnetDeviceInstanceNumber).
Examples:
In the i-Vu application
1 Use the BACnet Discovery feature to discover the BACnet Thermostat and its BACnet objects.
2 In the navigation tree, select the Analog Value called BacnetDeviceInstanceNumber.
MAC Address and BACnet Device Instance Number

3 Change the Present Value field (shown below) to the desired BACnet Device Instance Number.
4 Click Accept.
In an Analog Network Output microblock
To change the BACnet Device Instance Number from 16075 to 16113, the microblocks address would be:
bacnet://16075/AV:42/present_value, or
bacnet://16075/BACnetDeviceInstanceNumber
Subsequent reads/writes of this value will need to be done with the new device instance:
bacnet://16113/AV:42/present_value, or
bacnet://16113/BACnetDeviceInstanceNumber

Mount the BACnet Thermostat on an interior wall in the room to be controlled. Locate it where the occupant can easily read the LCD display and use the controls. If the built-in temperature sensor is being used to measure room temperature, place the thermostat where the temperature is representative of the general room conditions. Avoid cold or warm air drafts, radiant heat, and direct sunlight.
WARNING: Risk of electric shock and property damage. Disconnect power supply before making electrical connections. The installation is to be performed by a qualified electrician.
WARNING: The integrated circuits in the controller are sensitive to static currents. Take suitable precautions.
General
Installation 1 Separate the front display from the back plastic cover by inserting a small flat screwdriver into each of the
three slots as shown in the picture and rotating it gently. Keep the front display in a safe place.
2 Connect the wires as shown in the enclosed wiring diagram. All terminals accept 1x0.5mm2/24 AWG. If necessary, make changes to the DIP switches position as explained in this manual.
