Control Condenser Fan Run
In all models except the 700TF/I-3, the microprocessor senses the 115 volt output supplied to both compressors. If
either compressor is running, a signal is sent to the condenser fan relay on the control board to close, supplying
power to the condenser fan. If both compressors are off, the condenser fan is off. (See Figure 3-22)
NOTE: There is only one compressor on the model 700TF/I-3. The condenser fan cycles with this single compressor,
which along with the evaporator fan, will cycle off during defrost and may also cycle off for short periods of time if
the ambient temperature is low enough.
