INSTALLATION Installation Tabs Thermostat 1) Pull the thermostat off the base using tabs shown above. 2) Place base over wire hole in wall and mark mounting hole locations using base as a template. Drill mounting holes. 3) Fasten base snugly to wall using wall anchors and two mounting screws. Leveling is for appearance only and will not affect thermostat operation. 4) Connect wires to terminal block on base. Important: Wiring from equipment control should correspond with wiring to thermostat. (see Fig.

Advanced Installer Menu Faults Status This menu item lists current equipment fault conditions. If no faults are detected, this screen will show nothing. (See “System Fault Codes” on page 28.) USB Upload ADVANCED INSTALLER MENU The USB Upload menu displays a list of thermostat parameters that can be loaded to the thermostat from a USB memory device. If the USB port detects a USB memory device, this menu will automatically display.
Advanced Installer Menu Thermostat Summary Indicates the thermostat’s software and version. Heat Pump Lockout (outdoor sensor required) Available only for heat pump systems with indoor electric heat. This feature disables the heat pump and turns on auxiliary heat below the selected outdoor temperature. The temperature range is from 5° to 50°F.
Advanced Installer Menu Aux Lockout Temperature (outdoor sensor required) Available for heat pump systems. This setting is the maximum outdoor temperature that is acceptable for auxiliary heat to be used. Heat Cycle Rate Anticipation for heat cycle can be adjusted. Default setting is Medium. If you wish to have longer heat cycles, change to Slow. For shorter heat cycles change to Fast. ADVANCED INSTALLER MENU Cool Cycle Rate Anticipation for cool cycle can be adjusted. Default setting is Medium.
Advanced Installer Menu Installation Test Performs an equipment test to verify proper installation and performance. Only operable on communicating systems with ClimateTalk™. Check System Operation ADVANCED INSTALLER MENU Heating System 1. Press SYSTEM button until Heat is displayed. 2. Press to adjust thermostat setting 1° above room temperature. The heating system should begin to operate and the display will indicate Heat On. 3.
Main Menu Navigating through your thermostat menus Your thermostat features a simplified easy to understand menu structure. • Press to enter the Main Menu • Highlight a menu item using the buttons or • Enter the item by pressing • Use the or and the or to change menu items and settings • Press the Home button to display the Home Screen. • Press the Enter button to save any changes you have made and display the previous menu item.
Main Menu Time and Day Display When turned on, the current time and day are displayed on the home screen. Outdoor Temp Display When turned on, the outdoor temperature is displayed on the home screen (for use with outdoor sensor only). Humidity Display When turned on, the sensed humidity is displayed on the home screen. Alert Info Detail When turned on, provides additional information for maintenance and service reminders.
Main Menu • When you have completed setting all times and temperatures, press Enter to save and display the Heating Program menu. A checkmark appears to indicate the portion of schedule you have programmed Cooling Program After entering Heating Program, press to highlight “Switch to Cool Program” and press , or enter Cooling Program on the Main Menu.
Main Menu Program – Default is On. Select Off to disable the heating and cooling programs and maintain a constant temperature 24 hours a day. Air Filter Maintenance / Service Reminder / Humidifier Maintenance Default for each is Off. When set to On, a maintenance reminder will appear on the home screen when the system has run for the selected amount of time. The length of time for the maintenance reminder can be selected to a setting of 1 to 12 months. Use or . to select On or Off.
Main Menu Beeper – Default is On. Turns audible prompt on to indicate when a button is pressed. MAIN MENU Cycle Humidifier – Default if Off. This feature provides an option that reduces the water usage by up to 50% when a flow-through humidifier is controlled by the thermostat. It is recommended for use on flow-through humidifiers only. When turned On, the humidifier will cycle to turn off for 10 minutes after it has run for 10 minutes.
Main Menu Comfort or Dehum – Default is Off. Selecting either Comfort or Dehum will automatically reduce indoor humidity with a call for cooling if humidity is 2% above the humidity setpoint. If Comfort is selected, the system will slow the fan speed (variable speed blowers only) to increase the dehumidification process and cool based on the temperature setpoint. If Dehum is selected, the system makes the dehumidification a priority over temperature.
Main Menu Temperature Display Adjust – Default is 0°. Your thermostat was accurately calibrated at the factory. However, this option allows you to change the humidity or temperature displayed to match other thermostats in your home. Dehumidification Setpoint – Default is 95%. Setpoint is the percent humidity that the cooling system will attempt to maintain. Only available when dehumidification equipment is enabled (see Communicating Devices in Advanced Installer Menu).
Troubleshooting Reset Operation If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the system by performing a power reset. Note: Be sure to record the user’s Main Menu settings. When thermostat is reset, Main Menu and Programming will reset to factory settings. (Installer’s equipment setup options will NOT be affected by the reset.
Troubleshooting Possible Cause No Cool 1. Cooling system requires service. Heat, Cool or Fan 1. Possible short in Runs Constantly wiring. 2. Possible short in thermostat. 3. Possible short in heat/ cool/fan system. 4. FAN Switch set to Fan ON. Correction Action Check each wire connection to verify they are not shorted or touching together. No bare wire should stick out from under terminal block. Try resetting the thermostat as described above.
