INSTALLER/CONFIGURATION MENU
19)Comfort Alert with Active Protection – Turn this feature ON to enable active protection. This allows the thermostat to identify fault codes sent by the Comfort Alert module when compressor damage is possible and react to those codes by turning the compressor off. Fault codes from the Comfort Alert module will flash on the thermostat. (Refer to Comfort Alert Yellow Alert Codes in Troubleshooting section.) If a Comfort Alert module is not connected, or to disable active protection, turn this feature OFF. If a Comfort Alert module is connected and this feature is turned OFF, the thermostat will still receive and flash the fault codes from the Comfort Alert module, but the active protection will not be enabled to protect the compressor.
20 & 21) Select Filter Replacement Reminder and Set Run Time – Select the “Change Filter” reminder On or OFF. If selected On, press MENU to select the time
period from 25 to 1975 hours in 25 hours increments. In a typical system, 200 hours (default) of run time is approximately 30 days. After the selected time of blower operation, the thermostat will display “Change Filter” as a reminder to change or clean your air filter. When “Change Filter” is displayed, press MENU or RUN SCHED button to clear the display and restart the time to the next filter change.
22)Select Reversing Valve Output – The O/B option is factory set at “O” position. This will accommodate the majority of heat pump applications, which require the
changeover relay to be energized in COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” terminal, to energize the changeover relay in HEAT, the O/B option should be set at “B” position.
OPERATING YOUR THERMOSTAT
Choose the Fan Setting (Auto or On)
Press the FAN button to Auto or On.
Fan Auto is the most commonly selected setting and runs the fan only when the heating or cooling system is on.
Fan On runs the fan continuously for increased air circulation or to allow additional air cleaning.
Choose the System Setting
(Heat, Off, Cool, Auto, Emer)
Press the SYSTEM button to select:
Heat: Thermostat controls only the heating system.
Off: Heating and Cooling systems are off.
Cool: Thermostat controls only the cooling system.
Auto: Auto Changeover is used in areas where both heating and cooling may be required on the same day. AUTO allows the thermostat to automatically select heating or cooling depending on the indoor temperature and the selected heat and cool temperatures. When using AUTO, be sure to set the Cooling temperatures more than 1° Fahrenheit higher than the heating temperature.
Emer: (Heat Pump models) Thermostat controls only backup heating system.
Manual Operation for Non-Programmable Mode
Press the SYSTEM button to select Heat or Cool and use
the 
or 
buttons to adjust the temperature to your desired setting. After selecting your desired settings you can also press the SYSTEM button to select AUTO to allow the thermostat to automatically change between Heat and Cool.
IMPORTANT!
Second Stage Time Delay
Your thermostat is designed to determine the optimum time to activate the second stage. Simply raising the temperature in heating or lowering it in cooling will not always force the thermostat to bring the second stage on quickly. There is a time delay from
EXAMPLE: For the last 2 hours the thermostat is set on 70° and the room temperature is 70° with the equipment using only the first stage of heat. Since the equipment is keeping the temperature within 1° of setpoint, the thermostat will delay second stage for a longer time if you manually raise the temperature or if the room temperature quickly changes. Once the second stage comes on, it will come on sooner the next time there is a difference between the setpoint and the room temperature. The net effect of the staging program is that when the first stage is capable of making temperature the second stage will delay longer. When the thermostat calculates that first stage cannot make temperature in a reasonable time, the second stage will come on sooner. This built in function automatically optimizes the use of additional stages of heat or cool.
TROUBLESHOOTING
Comfort Alert Codes
The Comfort Alert diagnostics product monitors the air con- ditioning outdoor systems with single phase Copeland Scroll compressors. Abnormal system and electrical conditions are indicated by flashing ALERT codes on the yellow LED on the Comfort Alert module. The flash codes are transmitted to the thermostat by the Comfort Alert Thermostat interface module. The Comfort Alert compatible thermostat displays “Call For Service” that flashes at the same rate as the yellow LED on the Comfort Alert module.
