at all times. In case of controller breakdown the low pressure switch could be used for
emergency operation (rewiring required).
A crankcase heater is directly connected to the controller. The crankcase heater will be
energized when the ambient sensor is below a given value (10°C) and the compressor has been
off for a period of time (5 minutes). The minimum off time does not apply at initial power up.
In addition to the above, the [ CF ] EASY condensing unit has the following features:
 Liquid line assembly (filter drier and sight glass/moisture indicator)
 Anti-corrosion treatment to the condenser fins
The electronic controller is also the base controller for the connection of many optional and
customer supplied functions such as:
 Main load controller (or thermostat)
 Evaporator electric defrost heater contactor
 Evaporator fan contactor
 Superheat controller for one electronic expansion device (not available on CFLE models)
NOTE: For additional features please contact your local Application Engineering
representative.
