THERMOSTAT INDICATOR LAMPS
The red lamp marked “Check” will come on if there is any
problem that prevents the compressor from running when it
is supposed to be.
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 high head pressure, etc., that will
prevent compressor from operating will cause red lamp to
activate. This is a signal to the operator of the equipment to
place system in emergency heat position.
