UNIT OPERATION
COOLING OPERATION
During cooling operation, the main outdoor control will receive a
communicated demand signal along with the current space
temperature and setpoint. The control algorithm will then utilize
these signals to communicate the proper compressor speed,
OD fan speed, and ID blower CFM to match system output for
the required space load.
