Icm Condenser Fan Speed Control

This electronic head pressure control modulates condenser fan motor speed thereby varying the air volume through the condenser.

Icm condenser fan speed control. Install a fan speed control from grainger in a standard wall box for efficient control of ceiling attic kitchen or bathroom fans. The control monitors the head pressure by sensing the sub cooled liquid line temperature. Single or three phase fan speed controllers. Low speed cutoff field adjustable.

Identify the speed wires the remaining wires generally capped off with wire nuts are speed wires. By adjusting the condenser fan speed the icm330 controls the airflow through the condenser. I replaced the icm but the motor had the same problem. I removed the icm and the motor ran fine.

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. Fan coil relay controls. A single desired temperature pressure setpoint adjustment will result in precise. Cut phase controllers in master or slave version designed for adjustable voltage 3 ph motors from 8a to 60a.

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. Icm controls icm330 icm330 single phase head pressure control 120 480 vac the icm330 head pressure control helps maintain the correct condensing temperature pressure which results in a constant head pressure. Rotary fan controls have manual low speed trim adjustment to ensure proper restart after power.

Icm fan speed 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. 120 208 240 277 480 and 600 vac control. Line voltage accessories.

I replaced a condenser fan motor about a year ago with a oem from trane. Controls feature split capacitor shaded pole motors and are suitable for ganging. Line voltage three phase monitor. Locate the identification tag for the fan motor which will be somewhere on the fan or motor block.
