Introduction
FanTrol
The FanTrol, provided on all units, is a method of head
pressure control that automatically cycles the condenser
fans in response to ambient air temperature. This feature
maintains head pressure and allows the unit to run at low
ambient air temperatures.
RPS/RDT and RCS units have two independent refrigerant
circuits with one to four condenser fans being controlled
independently by the ambient air temperature of each circuit.
