Mode of Operation
The
Amana
®
2246008
is a programmable, manual or auto changeover, 2-stage heat, 2-stage cool thermostat. It
functions with air conditioning, heat pumps, gas, oil or electric heat systems. An outdoor sensor can be used to
monitor the outdoor temperature.
The thermostat activates the heating appliance when the room temperature is below the set heat temperature (by
the differential temperature). The
Amana
®
2246008
will stop outputting when the call for heat has been satisfied.
With heat pumps, the thermostat will not let the compressor come on for 4 minutes after it turns off. This protects
your compressor.
When the room temperature is greater than the set cool temperature (by the differential temperature), the cooling
device is activated.. The
Amana
®
2246008
will stop outputting when the call for cooling is satisfied. The thermostat
will not let the compressor come on for 4 minutes after it turns off. This protects your compressor.
The

®
2246008
has five possible operating modes:
OFF
,
Heat
,

mode. In
off mode, the thermostat will not turn on heating or cooling devices. The manual fan can be turned on in all operating
modes using the fan button. In heat mode, the thermostat controls the heating system. In the cool mode, the
thermostat controls the cooling system. In heat & cool mode, the thermostat controls both the heating and cooling
systems. In program mode, the thermostat will automatically be controlled by the set program. Program mode can
function with heat mode, cool mode, or heat & cool mode. The clock display alternates with the set temperature
display for heat & cool mode.
The program schedule can be overridden by changing the set temperature (up or down button). This puts the
