Control Condenser Fan Run
The microprocessor senses the 115 volt output supplied to both compressors. If either compressor is running, a sig-
nal 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 3-13)
NOTE: There is only one compressor on the model 700TF/I-2 and 700TF/I-2V. The condenser fan cycles with this sin-
gle compressor. In the model 700TF/I-2V, the condenser fan along with the compressor and evaporator fan will only
cycle off during defrost and may also cycle off for short periods of time if the ambient temperature is low enough.
