Icm Condenser Fan Speed Control

Line voltage single phase monitor.

Icm condenser fan speed control.

Cut phase controllers in master or slave version designed for adjustable voltage 3 ph motors from 8a to 60a. This electronic head pressure control modulates condenser fan motor speed thereby varying the air volume through the condenser. Icm fan speed control. Single or three phase fan speed controllers.

Low speed cutoff field adjustable. Controls feature split capacitor shaded pole motors and are suitable for ganging. User may set the minimum rpm level at which the condenser fan should operate high temperature bypass applies full voltage to the condenser fan under normal conditions rohs compliant lead free design or global use f. Input output voltage line.

On the other end one wire will go to the terminal block labeled neutral or line 2 and a wire going to the fan relay will control fan speed. Line voltage accessories. 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. I had to install a fan cycling control.

This unit had a icm fan speed control and worked with the original motor but the new motor was drawing high amps and going off on overload. I removed the icm and the motor ran fine. The control monitors the head pressure by sensing the sub cooled liquid line temperature. A single desired temperature pressure setpoint adjustment will result in precise.

Identify the speed wires the remaining wires generally capped off with wire nuts are speed wires. Locate the identification tag for the fan motor which will be somewhere on the fan or motor block. I replaced the icm but the motor had the same problem. 120 208 240 277 480 and 600 vac control.

Line voltage three phase monitor. By adjusting the condenser fan speed the icm330 controls the airflow through the condenser. I replaced a condenser fan motor about a year ago with a oem from trane. Fan coil relay controls.
