CAUTION Follow the Installation Instructions before proceeding. Set the thermostat mode to “OFF” prior to changing settings in setup or restoring Factory Defaults.
NOTE: Due to variations in environmental conditions, it is not always possible to achieve the desired humidification or dehumidification setpoint. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation
Auto-Changeover:
A mode in which the thermostat will turn on the heating or cooling based on room temperature demand.
Cool Setpoint: The warmest temperature that the space should rise to before cooling is turned on (without regard to deadband).
Deadband: The number of degrees the thermostat will wait, once a setpoint has been reached, before energizing heating or cooling.
Dehumidify: To reduce the amount of moisture in the air.
Differential: The forced temperature difference between the heat setpoint and the cool setpoint.
Heat Setpoint: The coolest temperature that the space should drop to before heating is turned on (without regard to deadband).
Humidify: To increase the amount of moisture in the air.
Icon: The word or symbol that appears on the thermostat display.
Mode: The current operating condition of the thermostat (i.e. Off, Heat, Cool, Auto, Program On).
Non-Programmable Thermostat: A thermostat that does not have the capability of running Time Period Programming.
Temperature Swing: Same as Deadband.
Display Features
During Setup and Programming
Press the UP or DOWN buttons to modify the selection. Press the MODE button to advance and confirm through the setup steps.
The select mode by pressing the MODE button. Heating Only – The HEAT setting indicates the temperature the room has to reach before the furnace will turn on to heat the room.
Cooling Only – The COOL setting indicates the temperature the room has to reach before the air conditioner will turn on to cool the room.
Heating or Cooling (Auto-Changeover) – AUTO will automatically select heat or cool based on room temperature demand.
OFF – OFF indicates both heating and air conditioning systems are turned off.
Selecting Your Desired Temperature
AUTO-CHANGEOVER MODE – Pressing the UP or DOWN buttons in Auto mode will adjust both the heat and cool setpoints simultaneously. To adjust the heat and cool setpoints individually, choose HEAT mode to adjust the heat setpoint and COOL mode to adjust the cool setpoint, then return to AUTO mode.
HEAT OR COOL MODE – Pressing the UP or DOWN buttons in Heat or cool mode will adjust only the heat or cool setpoints individually displayed.
NOTE – This thermostat has a fixed two-degree deadband. With a Cool setpoint of 72 degrees Fahrenheit, cooling will energize at a room temperature of 74 degrees. With a Heat setpoint of 68 degrees Fahrenheit, heating will energize at 66 degrees.
Using the Reset Filter Button
Reset Filter – Press the RST FILTER button to view the current filter runtime. Press the OUTDOOR button to reset the filter runtime counter to 0. Press the RST FILTER button again to return to normal operation
NOTE: Override may only be used when the Dry Contact has forced the thermostat into the Unoccupied mode
Unoccupied Operation
During a Dry Contact forced unoccupied period pressing the OVERRIDE button will force the thermostat into the mode it was in before the Dry The contact forced it into the Unoccupied mode. For example: if the thermostat was in the Auto mode and the Dry Contact forced it into Unoccupied mode, pressing OVERRIDE will force the thermostat back into Auto mode. The remaining override time will be displayed in the upper left corner of the display. Each press of the OVERRIDE button will add another 30 minutes of time for up to 4 hours. If the maximum time has been set, the next press of the OVERRIDE button will reset the timer and return the thermostat to the Unoccupied mode.
Viewing the Outdoor and Remote Temperature Sensors
OUTDOOR TEMP – Press the OUTDOOR button to view the current outdoor temperature. Pressing the OUTDOOR button again to return to normal operation.
REMOTE TEMP – Press the ACCESSORY button to enter the accessory setup screen. Press the UP button to view linked wireless and wired sensors and other accessories. Press the ACCESSORY button to return to the main screen.
Note: If no outdoor sensor is connected, 2 dashes [- -] will appear with the first button press
Viewing and Setting the Indoor Humidity Sensor
Press the HUMIDITY button to display the current humidity measured at the thermostat. The room’s relative humidity is displayed in the top left corner. The humidification setpoint appears in the larger center display and can be adjusted using the UP or DOWN buttons. Press the MODE button to view and adjust the dehumidification setpoints. Press the HUMIDITY button again to confirm settings and return to normal operation.
Note: Due to variations in environmental conditions, it is not always possible to achieve the desired humidification or dehumidification setpoint.
