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, select dF (default)
if your system has a fossil fuel (gas or oil) Auxiliary 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)
Economizer Feature
– This item allows longer Y1 cycles
for cooling with outdoor air.
28)
Pre-occupancy Purge
(PP)
– Selects the number of
hours for the pre-occupancy purge time from 0 to 1, 2 or 3
hour with the
or
buttons.
When the pre-occupancy purge time is greater than 0
hours, the blower output ("G" terminal) will energize the
number of pre-occupancy purge hours before the next
programmed occupancy time period. During this pre-
purge time the A1 terminal will also be energized.

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.

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.
31)
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.
