Icm Condenser Fan Speed Control

By adjusting the condenser fan speed the icm330 controls the airflow through the condenser.

Icm condenser fan speed control.

Single or three phase fan speed controllers. Rotary fan controls have manual low speed trim adjustment to ensure proper restart after power. I had to install a fan cycling control. Identify the speed wires the remaining wires generally capped off with wire nuts are speed wires.

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. 120 208 240 277 480 and 600 vac control. Cut phase controllers in master or slave version designed for adjustable voltage 3 ph motors from 8a to 60a.

Fan coil relay controls. I replaced a condenser fan motor about a year ago with a oem from trane. I replaced the icm but the motor had the same problem. Controls feature split capacitor shaded pole motors and are suitable for ganging.

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. Install a fan speed control from grainger in a standard wall box for efficient control of ceiling attic kitchen or bathroom fans. Low speed cutoff field adjustable. Line voltage single phase monitor.

This electronic head pressure control modulates condenser fan motor speed thereby varying the air volume through the condenser. 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. 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. Line voltage three phase monitor.

The control monitors the head pressure by sensing the sub cooled liquid line temperature. Icm fan speed control. Input output voltage line. A single desired temperature pressure setpoint adjustment will result in precise.
