It should remain closed without bulging. 3. Align the UWP with the thermostat, and push gently until the thermostat snaps in place. 4. Turn the power on at the breaker box or switch. System operation settings 1. Press Menu, and then press the Mode (+) button to cycle to the next available System mode. 2. Cycle through the modes until the required System mode is displayed, and then press Done. NOTE: Available System modes vary by model and system settings. System modes: ‒Auto: Thermostat selects heating or cooling as needed. ‒Heat: Thermostat controls only the heating system. ‒ Cool: Thermostat controls only the cooling system. ‒Em heat (TH3210U only): For heat pumps with auxiliary heat. Thermostat controls auxiliary heat. Compressor is not used. ‒ Off: Heating and cooling system is off. Fan will still operate if fan is set to On. NOTE: Heat On/Cool On may flash for 5 minutes due to compressor protection. Fan operation settings 1. Press Menu, and then press the Fan (-) button to cycle to the next available Fan mode. 2. Cycle through the modes until the required Fan mode is displayed, then press Done . NOTE: Available Fan modes vary with system settings. Fan modes: ‒ Auto: Fan runs only when the heating or cooling system is on. ‒On: Fan is always on.6 Installer setup (ISU) NOTE: The thermostat enters installer setup the first time it is powered up during installation. To re-enter the System Setup from the Home Screen, press and hold the Menu button for approximately 5 seconds. 1. Select System Setup options. Press Edit (-) to change values or select from available options. Then press Next (+) to save changes and advance to the next System Setup number. See “System Setup options” on the next page for a full list of System Setup numbers and options . Repeat until all of the System Setup options have been set, and then press Done. The thermostat will save and exit to the home screen. 2. Continue to “Installer setup (ISU)” on page 6. Setup number Option number7 Installer setup (ISU) ISU Setup Number and DescriptionOptions (factory default in bold) 125 = Temperature Indication Scale 0 = Fahrenheit 1 = Celsius 200 = Heating System Type 1 = Conventional Forced Air Heat 2 = Heat Pump 3 = Radiant Heat 5 = None (Cool Only) Notes: • Default varies based on model. • This option selects the basic system type your thermostat will control. 205 = Heating Equipment Type Conventional Forced Air Heat: 1 = Standard Efficiency Gas Forced Air 2 = High Efficiency Gas Forced Air 3 = Oil Forced Air 4 = Electric Forced Air 5 = Hot Water Fan Coil Heat Pump: Note: ISU 205 is not shown when ISU 200 is set for heat pump. Radiant Heat: 9 = Hot Water Radiant Heat 12 = Steam Note: This option selects the equipment type your thermostat will control. This feature is NOT displayed if feature 200 is set to Cool Only. 218 = Reversing Valve O/B 0 = O (O/B in Cool) 1 = B (O/B in Heat) Note: This option is only displayed if the Heat Pump is configured. Select whether reversing valve O/B should energize in cool or in heat. 220 = Cool Stages / Compressor Stages (200=Conv / 200=HP) 0, 1 Note: Select how many Cool or Compressor stages of your equipment the thermostat will control. Set value to 0 if you do not have Cool Stage/ Compressor Stage. 221 = Heat Stages / Backup Heat Stages Heat Stages: 1 Backup Heat Stages: 0, 1 Note: Select how many Heat or Aux/E stages of your equipment the thermostat will control. 230 = Fan Control in Heat 1 = Equipment Controls Fan 2 = Thermostat Controls Fan Note: This ISU is only displayed if ISU 205 is set to Electric Forced Air or Fan Coil. 300 = System Changeover 0 = Manual 1 = Automatic Note: Thermostat can automatically control both heating and cooling to maintain the desired indoor temperature. To be able to select “automatic” system mode on thermostat home screen, turn this feature ON. Turn OFF if you want to control heating or cooling manually. Continued on next page.8 ISU Setup Number and DescriptionOptions (factory default in bold) 303 = Auto Changeover Differential 0 °F to 5 °F 0 °C to 2.5 °C Note: Differential is NOT deadband. Differential means how far past the setpoint before switching to the mode selected. Deadband setup is not an option. An advanced algorithm fixes the deadband at 0 °F. This is more advanced than previous thermostats. 340 = Backup Heat Droop (TH3210U only) 0 = Comfort 2 = 2 °F 3 = 3 °F 4 = 4 °F 5 = 5 °F 6 = 6 °F 7 = 7 °F 8 = 8 °F 9 = 9 °F 10 = 10 °F 11 = 11 °F 12 = 12 °F 13 = 13 °F 14 = 14 °F 15 = 15 °F 350 = Upstage Timer to Backup Heat (TH3210U only) 0 = Off 1 = 30 minutes 2 = 45 minutes 3 = 60 minutes 4 = 75 minutes 5 = 90 minutes 6 = 2 hours 7 = 3 hours 8 = 4 hours 10 = 5 hours 365 = Compressor Cycle Rate (Stage 1) 1 - 6 Note: This ISU is only displayed when Cool /Compressor Stage is set to 1 stage. Cycle rate limits the maximum number of times the system can cycle in a 1 hour period measured at a 50% load. For example, when set to 3 CPH, at a 50% load, the most the system will cycle is 3 times per hour (10 minutes on, 10 minutes off). The system cycles less often when load conditions are less than or greater than a 50% load. 370 = Heating Cycle Rate (Stage 1) 1 - 12 Note: This ISU is only displayed when Heat Stage is set to 1 stage. Cycle rate limits the maximum number of times the system can cycle in a 1 hour period measured at a 50% load. For example, when set to 3 CPH, at a 50% load, the most the system will cycle is 3 times per hour (10 minutes on, 10 minutes off). The system cycles less often when load conditions are less than or greater than a 50% load. The recommended (default) cycle rate settings are below for each heating equipment type: Standard Efficiency Gas Forced Air = 5 CPH; High Efficiency Gas Forced Air = 3 CPH; Oil Forced Air = 5 CPH; Electric Forced Air = 9 CPH; Fan Coil = 3 CPH; Hot Water Radiant Heat = 3 CPH; Steam = 1 CPH. 375 = Heating Cycle Rate Auxiliary Heat (TH3210U only) 1 - 12 387 = Compressor Protection 0 = Off 1 - 5 minutes Note: The thermostat has a built in compressor protection (minimum off timer) that prevents the compressor from restarting too early after a shutdown. The minimum-off timer is activated after the compressor turns off. If there is a call during the minimum-off timer, the thermostat shows “Wait” in the display. This ISU is displayed if ISU 220 is set to at least 1 stage.

The thermostat can display up to 3 °F (1.5 °C) lower or higher than the actual measured temperature. NOTE: Once you have cycled through all of the System Setup numbers, press Done to save and exit to the home screen. Setup Complete You have now finished installing and setting up your thermostat.
