OUTDOOR UNIT CONTROLLER (OUC)
The Outdoor Unit Controller (OUC) includes
a temperature sensing head pressure
control which enables the system to com-
pensate for outdoor ambient temperatures
below 20°C on cooling cycle, and above
15°C on heating cycle. The OUC also has
features which protect against icing or
overheating of coils, rapid cycling of the
compressor and loss of refrigerant charge.
If the outdoor unit fans take some time
to begin rotating when the system is
powered on, or they don't appear to be
rotating appropriately while the compressor
is running, consult the OUC label on
the electrical box. If necessary, refer
to
temperzone
for further diagnostic
information.
