THERMOSTAT INDICATOR LAMPS
The red lamp will come on if there is any problem that
prevents the compressor from running when it is
supposed to be.
EMERGENCY HEAT MODE
The operator of the equipment must manually place the
system switch in this position. This is done when there
is a known problem with the unit, or when the red lamp
comes on indicating a problem.
COMPRESSOR MALFUNCTION LIGHT
Actuation of the red lamp is accomplished by a relay
output from the heat pump control board which is
factory installed. Any condition such as loss of charge,
high head pressure, etc., that will prevent compressor for
operating will cause red lamp to activate. This is a
signal to the operator of the equipment to place system
in emergency heat position.
