temperature. 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 flashing, the compressor lockout feature is

Choose the Fan Setting (Auto or On or Prog)
There are two fan features on the 1F95-1291:
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 Comfort 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.
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
configured in HP1 or HP2 mode.
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.
