Condenser Fan Motor Speed Control

Some p266 controls provide optional control of up to three auxiliary fixed speed fans or fan stages.

Condenser fan motor speed control.

Variable speed ecm condenser fan motors are used in condensers for the high efficient models so that the fan speed for the condenser can be modulated according to the load of the system. They are also used in condensers that have two compressors or a two stage compressor. The johnson controls condenser fan speed control is a cost effective weather resistant durable motor speed control. How to connect the fan wire easy to understand fan coil connector 5 wire condenser fan motor wiring diagram simplest.

The ecm variable speed fan motors are used in condensers that have a modulating compressor. The fan speed control utilizes a liquid line temperature sensor or a high pressure transducer to control the fan speed. Approved for single phase psc motors commonly used in many refrigeration and air conditioning condenser fan applications. Cut phase controllers in master or slave version designed for adjustable voltage 3 ph motors from 8a to 60a.

Wide adjustable pressure throttling range. There are two temperature inputs and three outputs pwm 0 10 vdc and 10 0 vdc to control the ecm or vfd variable speed fan motor. As the condenser pressure or liquid line temperature starts to fall the fan motor will slow down. The control monitors the head pressure by sensing the sub cooled liquid line temperature.

3 speed ac fan running capacitor. This electronic head pressure control modulates condenser fan motor speed thereby varying the air volume through the condenser. Single or three phase fan speed controllers. Instead of slamming the condenser fan off and on the fan speed control will slow the fan down.
