Input output voltage line.
Icm condenser fan speed control.
Line voltage single phase monitor.
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.
Low speed cutoff field adjustable.
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.
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.
Icm fan speed control.
120 208 240 277 480 and 600 vac control.
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.
I removed the icm and the motor ran fine.
Cut phase controllers in master or slave version designed for adjustable voltage 3 ph motors from 8a to 60a.
The control monitors the head pressure by sensing the sub cooled liquid line temperature.
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.
I replaced a condenser fan motor about a year ago with a oem from trane.
Install a fan speed control from grainger in a standard wall box for efficient control of ceiling attic kitchen or bathroom fans.
Line voltage three phase monitor.
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.
A single desired temperature pressure setpoint adjustment will result in precise.
Line voltage accessories.
By adjusting the condenser fan speed the icm330 controls the airflow through the condenser.
Identify the speed wires the remaining wires generally capped off with wire nuts are speed wires.
Fan coil relay controls.
Rotary fan controls have manual low speed trim adjustment to ensure proper restart after power.
