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 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.

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.
