Once the thermostat is installed and properly configured, test the equipment by following these steps:

  • Turn on power to the system.
  • Fan Operation
    • If your system does not have a “G” terminal connection, skip to “Heating System” below.
    • Press the “Fan” button on the thermostat and select the “On” position. The blower should begin to operate.
    • Press the “Mode” button to turn off the system. Then press the “Fan” button on the thermostat and select the “Auto” position. The blower should stop immediately.
  • Circulating Fan
    • Press the “Menu” button on the thermostat and press the “Next” button until you reach the “Fn” screen.
    • Adjust the % run time from 10%-100% in 5% increments by using the arrow up or down buttons (default is OFF), then press “Exit”.
    • The % run time is the percentage of time the fan shall run in a day. This calculation takes into account the amount of time the heating, cooling and continuous fan have run during the same day. 
  • Heating System
    • Press the “Mode” button on the thermostat and select the “Heat” position.
    • Press the up arrow on the thermostat and adjust the setting to 1° above the current room temperature. The heating system should begin to operate and the thermostat will indicate “Heating” of “Heating Auxiliary” on the screen.
    • For heat pumps with auxiliary, press the up arrow on the thermostat and adjust the setting to 3° above the current room temperature. The auxiliary heat should begin to operate and the thermostat will indicate “Heating Auxiliary” on the screen.
    • Press the down arrow on the thermostat and adjust the setting to 1° below the current room temperature. The heating system should stop operating and “Heating” or “Heating Auxiliary” will disappear from the screen.
  • Auxiliary System (only for heat pumps with auxiliary)
    • Press the “Mode” button on the thermostat and select the “Aux” position. This bypasses the heat pump and runs auxiliary-only heat.
    • Press the up arrow on the thermostat and adjust the setting to 1° above the current room temperature. The auxiliary heating system should begin to operate and the thermostat will indicate “Heating Auxiliary” on the screen.
    • Press the down arrow on the thermostat and adjust the setting to 1° below the current room temperature. The auxiliary heating system should stop operating and “Heating Auxiliary” will disappear from the screen.
  • Cooling System
    • Press the “Mode” button on the thermostat and select the “Cool” position.
    • Press the down arrow and adjust the setting to 1° below the current room temperature. The blower should come on immediately on high speed, followed by cold air circulation. The thermostat will indicate “Cooling” on the screen. Note that there can be up to a 5 minute delay for this process. This is indicated by a flashing setpoint temperature.
    • Press the up arrow and adjust the setting to 1° above the current room temperature. The cooling system should stop operating and “Cooling” will disappear from the screen.
    • If you encounter any issues while testing the equipment, refer to the troubleshooting actions on page 17.
  • Humidification
    • Press the “Mode” button on the thermostat and select the “Heat” position.
    • Press the up arrow on the thermostat and adjust the setting to 1° above the current room temperature. The heating system should begin to operate and the thermostat will indicate “Heating” on the screen.
    • Press the “Menu” button on the thermostat and press the “Next” button until you reach the “H SP” screen.
    • Turn Humidification On by pressing either the Up or Down button until the humidity set point is higher than the current room humidity. Humidity can be adjusted from 5%-50% in 5% increments, then press “Exit”.
    • Check to ensure humidifier is running.
    • Press the down arrow on the thermostat and adjust the setting to 1° below the current room temperature. The heating and humidification systems should both stop operating.
  • Dehumidification
    • Press the “Mode” button on the thermostat and select the “Cool” position.
    • Press the down arrow and adjust the setting to 1° below the current room temperature. The blower should come on immediately on high speed, followed by cold air circulation. The thermostat will indicate “Cooling” on the screen. Note that there can be up to a 5 minute delay for this process. This is indicated by a flashing setpoint temperature.
    • Press the “Menu” button on the thermostat and press the “Next” button until you reach the “dH SP” screen.
    • Turn Dehumidification On by pressing either the Up or Down button until the humidity setpoint is lower than the current room humidity. Humidity can be adjusted from 40% to 95% in 5% increments, then press “Exit”.
    • Depending on installed equipment, check that the system fan speed has slowed, the dehumidifier is running, or the system cools up to 3° below temperature set point or until the humidity set point is reached.
    • Press the up arrow and adjust the setting to 1° above the current room temperature. The cooling system and dehumidifier (if applicable) should both stop operating.
