• Page 8: Installer/configuration menu Keypad lockout and partial lockout allow only the selected temperature limits to operate. When the outdoor temperature falls below the selected temperature, the gas heat will begin. The dual fuel setting influences when the second stage comes on, with a factory default of 05. The compressor delay is factory set to 60 seconds but can be adjusted from 0 to 99 seconds. Auxiliary off setting inhibits the auxiliary heating stage based on outdoor temperature. The fast cool feature operates the cooling stages similarly to fast heat when the temperature is lowered. Remote temperature sensor enabled allows a remote sensor to display temperature in the clock digits. The dual fuel feature is applicable only in heat pump modes and can be enabled or disabled. The Change UV Lamp feature reminds users to maintain the UV system after a set time of operation. The Change Filter feature reminds users to change or clean the air filter after a specified blower operation time.
• Page 9: Operating your thermostat Caution: Check thermostat operation to prevent compressor and/or property damage. Cooling: Select Cool and adjust the thermostat setting below room temperature to activate the cooling system. Fan operation: Turn on power to the system and adjust the temperature setting to initiate cooling. Caution: Do not allow the compressor to run unless the oil heaters have been operational for 6 hours. Choose the fan setting: Fan Auto runs the fan only when the heating or cooling system is operating. Heating: Select Heat and adjust the thermostat setting to initiate the heating system. Emergency mode: Bypasses the heat pump to use the heat source wired to terminal W/E, W2. Choose the system setting: Options include Cool, Off, Heat, Emergency, and Auto. Manual operation for non-programmable mode: Adjust temperature settings to control heating or cooling. Emergency heating system: Adjust the thermostat setting to activate the emergency heating system.
• Page 10: Operating your thermostat involves understanding the override period, which can range from 15 minutes to 7 days. Manual operation allows you to bypass the program and adjust the temperature as desired. The temporary hold period can be canceled at any time by pressing Run Schedule. To copy a program from one day to another, enter the program for the day or select the day you wish to copy. The display will show Copy next to the SYSTEM key when copying a program. The real-time clock adjusts automatically for daylight saving time, incrementing one hour in March and decrementing in November. You can enable or disable the daylight saving feature in the installer configuration menu. When programming, you may copy the program from one day to another using the Copy key. Press Run Schedule to return to normal operation after programming is complete. The thermostat will run your program once all times and temperatures match your desired heating schedule.

• Page 12: Programming worksheet for reprogramming 5+1+1 and 7 day program. Heating program includes wake up, leave for work, return home, and go to bed settings. Cooling program includes wake up, leave for work, return home, and go to bed settings. Wired remote temperature sensing allows for temperature display from the thermostat or remote sensor. One remote temperature sensor can be installed indoors or outdoors with a maximum cable length of 100 meters. The thermostat must have a 24 VAC common connection for the remote sensor to operate. The remote sensor can be enabled or disabled in the installer/configuration menu. When enabled, the display alternates between time and remote temperature. Indoor and outdoor temperature ranges are specified for the remote sensor. Remote sensor settings include options for indoor or outdoor selection.
• Page 13: Programming Averaging or weighting remote sensors The thermostat will weight or average the temperature of the indoor remote sensor with the local sensor in the thermostat for each program period. The averaging will be active only when the local sensor and the indoor remote sensor are both functional and enabled in the Installer/Configuration menu. When the thermostat is configured for Heat Pump mode and the Dual Fuel feature is selected on, the thermostat can monitor the outside temperature using remote sensor F145-1378 or use software logic to determine when to switch to gas heat and shut down the compressor. The user selectable temperature is called the dual fuel temperature setpoint, dF and is set in the Installer/Configuration menu. A higher temperature or dual fuel setting will provide a smaller stage separation between the heat pump and Aux to give more comfort. In normal operation of the thermostat, the current temperature displayed will be the weighted average of the local sensor and the remote sensor. After the dual fuel temperature setpoint is set, a delay, Cd, can be set for compressor shutdown after the auxiliary stage is energized. Blower balance point for heating Comfort Alert Codes The Comfort Alert diagnostics product monitors the air conditioning outdoor systems with single phase Copeland Scroll compressors.
• Page 14: Troubleshooting Reset operation: If a voltage spike or static discharge causes erratic thermostat operation, reset by removing batteries for 2 minutes. No heat/no cool/no fan: Common problems include a blown fuse, tripped circuit breaker, or loose connections. No heat: Possible causes include an unlit pilot light or a furnace lock-out condition. Diagnostic: Set the system switch to heat and raise the setpoint above room temperature to check thermostat operation. No cool: Similar diagnostic steps as no heat, but set the thermostat to cool and lower the setpoint. Heat, cool, or fan runs constantly: Check for wiring shorts or thermostat issues. Thermostat setting & thermometer disagree: The thermometer can be adjusted +/- 4 degrees. Furnace cycles too fast or too slow: Cycle rate may be influenced by thermostat location or heating system size. Forgot keypad lockout code: Press the menu key for 20 seconds to unlock the thermostat. Blank display or keypad not responding: Use the reset operation to resolve issues.
