INSTALLER/CONFIGURATION MENU

24)Limited Cool Range – This feature provide a minimum setpoint temperature for cool. The default setting is 45°F. It can be changed between 46°F and 82°F by pressing the

or button.

25)Select Compressor Off (CO) Feature Using Outdoor Sensor – This feature is applicable only in heat pump modes and with an outdoor sensor installed and enabled. When CO is enabled by selecting a temperature >05°F (-15°C), the thermostat will use the outdoor sensor tem- perature to determine when to switch to gas heat and shut down the compressor.

When the outdoor temperature goes below the selected temperature, the gas heat will begin. Default is 05 (Off or disabled), but can be set in the range of 06 to 50 using the

or buttons.

Select dF or EA – If CO is set > 05°F (-15°C), select dF (default) if your system has a fossil fuel (gas or oil) Auxil- iary heat. Select EA if your system has Electric Auxiliary heat and you want the compressor to continue to run while calling for Auxiliary stage.

Select Compressor Delay (Cd) – If dF is selected, after the auxiliary heat is turned on, the compressor(s) shut down is delayed for the time selected (in seconds). This delay is factory set to 60, but can be set in the range of 0

to 99 using or buttons.

26)Select Auxiliary Off (AO) – This feature is applicable only in heat pump modes and with an outdoor sensor installed and enabled. Select the temperature that will inhibit the auxiliary heating stage. As long as the outdoor tempera- ture is above the setpoint, the auxiliary heat will not turn on. The default setting is 80, but can be set in the range of 35 to 79. A setting of 80 disables this feature.

27)Select Filter Replacement Reminder and Set Run Time Select the "Change Filter" reminder On or OFF. If se- lected 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 fi lter. When "Change Filter" is displayed, press MENU or RUN SCHED button to clear the display and restart the time to the next fi lter change.

28)Change UV Lamp – This feature allows the thermostat to display the words "Change UV Lamp" (Call for Service of UV bulb) after a set time of UV bulb operation. This is a reminder to maintain your UV system at optimum level of operation. When enabled the factory set interval for "Change UV Lamp" to be displayed is 350 days of UV bulb operation and can be adjusted in 25 day increments. This should be adjusted with respect to the bulb's recom- mended maintenance schedule.

When "Change UV Lamp" is displayed, you can clear it by pressing MENU.

29)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 thermo- stat 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.
