Compressor Time Delay
A time delay of approximately three

The time delay occurs
automatically after a mode is selected
or a power event occurs to ensure
pressure in the compressor is equalized
appropriately, to prevent damage.

conditioner or controller is interrupted,
the system will restart automatically
with the last status and operational
parameter set-points once the power is
restored.
