OPERATING YOUR THERMOSTAT
If at any time during testing your system does not operate
properly, contact a qualifi ed service person.
Fan Operation
If your system does not have a G terminal connection, skip to
Heating System.
1. Turn on power to system.
2. Press FAN key to ON position. The blower should begin
to operate.
3. Press FAN key to AUTO position. The blower should
stop immediately.
To prevent static discharge problems, touch side of
thermostat to release static build-up before touching
any keys.
NOTE
Check Thermostat Operation
Do not allow the compressor to run unless the com-
pressor oil heaters have been operational for 6 hours
and the system has not been operational for at least
5 minutes.
CAUTION !
Heating
1. Press SYSTEM key to select HEAT. If the auxiliary heating
system has a standing pilot, be sure to light it.
2. Press to adjust thermostat setting to 1° above the room
temperature. The heat pump system should begin to oper-
ate. The display should show "System On". However, if
the system confi guration is set to HP1 or HP2 and setpoint
temperature display is fl ashing, the 5 minute compressor
lockout feature is operating (see Confi guration menu, item
11).
3. Adjust temperature setting to 3° above room temperature.
If your system configuration is set at MS2, HP1 or HP2,
the auxiliary heat system should begin to operate and the
display will show "System On +2".
4. Press to adjust the thermostat below room tempera-
ture. The heating system should stop operating.
Emergency Mode
Applies only to Heat Pump Systems
Emergency Heat (System EM Position) bypasses the Heat
Pump to use the heat source wired to terminal W/E, W2 on
the thermostat. EM is typically used when compressor opera-
tion is not desired, or you prefer back-up heat only.
1. Press SYSTEM key to select EM. “EM Heat Mode” will
fl ash on the display.
2. Press to adjust thermostat setting above room tem-
perature. The Emergency heating system will begin to
operate. The display will show “System On” fl ashing “EM
Heat Mode” and “Heat” to indicate that the Emergency sys-
tem is operating.
3. Adjust temperature setting to 3° above room temperature.
Any additional stages of auxiliary heat should begin to
operate and the display will show "System On +2".
4. Press to adjust the thermostat below room tempera-
ture. The heating system should stop operating.
Cooling
1. Press SYSTEM to select COOL.
2. Press to adjust the thermostat setting below room tem-
perature. The blower should come on immediately on high
speed, followed by cold air circulation. The display should
show "System On". If the setpoint temperature display is
fl ashing, the compressor lockout feature is operating (see
Confi guration menu, item 5).
3. Adjust temperature setting to 3° below room temperature.
The second stage cooling should begin to operate and the
display should show "System On +2".
4. Press to adjust the temperature setting above room
temperature. The cooling system should stop operating.
Choose the Fan Setting (Auto or On or Prog)
There are three fan features on the 1F95-1280:
1. Fan Auto/On – Traditional Fan Settings
Press Fan to select Auto or On. The most commonly
used setting is Auto. Fan Auto runs the fan only when
the heating or cooling system is operating. Selecting Fan
On runs the fan continuously for increased air circulation
or to allow additional air cleaning if the system is equipped
with an Electronic Air Cleaner.
2. FAN Prog – Comfort Circulating Fan Feature
Pressing FAN until FAN Prog appears activates the Com-
fort Circulating Fan Option. This causes the thermostat to
cycle the fan on for 10 minutes and off for 20 minutes if the
thermostat has not called for heat or cool during the past
60 minutes. This assures moderate air circulation even
when the heating and cooling equipment is not cycling.
3. FAN On Prog. – Programmable Fan
FAN On Prog indicates that a time period has FAN Prog
selected in the Set Schedule mode (see Programmable
Fan Option). The fan will run continuously through the pe-
riod until the next period begins. To override FAN On Prog,
press the FAN key to select Auto for the fan to run only
when the heating or cooling system is operating.
Tip: Running the fan more frequently will increase your
energy consumption. Most systems use a 1/2 or 1/3 HP
electric motor to power the fan.
Choose the System Setting
(Cool, Off, Heat, Em, Auto)
Press the SYSTEM key to select:
Cool: Thermostat controls only the cooling system.
Off: Heating and Cooling systems are off.
Heat: Thermostat controls only the heating system.
Em: Setting is available only when the thermostat is confi g-
ured in HP1 or HP2 mode.
To prevent compressor and/or property damage, if the
outdoor temperature is below 50°F, DO NOT operate
the cooling system.
