OPERATING YOUR THERMOSTAT IMPORTANT!
Choose the Fan Setting (Auto or On)
Set the FAN Switch 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

simultaneously to change to the other mode.
The programs per week can be changed to P2 or P0 by
pressing the
or keys. A selection of 0 Days for
non-programmable will eliminate the need for EMR, and
that step in the menu will be skipped.
19 & 20) Select Automatic Schedule – 1F85 only, with just
one touch of the Auto Schedule key this feature allows
you to program a desired comfort temperature into all the
program periods along with a 6° set back for night peri-
ods of both Heat and Cool programs. Factory default is
“On” for both. When Heat AS On and Cool AS On are
activated while in Heat or Cool mode, select desired
setpoint temperature and press Auto Schedule. This
value will be copied into all the morning, day and evening
program periods. The night program periods will have a
6°F set back.
21 & 22) Select Fast Second Stage ON or OFF – Heat
pump or Multi-stage only, in the run mode, with the fast
Heat feature enabled (FA Heat On), if the Heat setpoint
temperature is manually raised by 3°F (2°C) or more
above the actual temperature using
the second
stage will energize immediately. With FA OFF, second
stage will not energize until the setpoint temperature is
1°F or more above actual temperature for more than ten
minutes. The Fast Cool feature (FA Cool) provides the
same controls when the setpoint temperature is lowered.
23) 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.
24) Select Daylight Saving Time Calculation – 1F85 only,
this feature will allow the thermostat to calculate the DST
automatically and apply it to the Real Time Clock display.
Default On. Use
or touch keys to select the
feature OFF.
25 & 26) 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.
27) 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.
