Line voltage three phase monitor.
Icm condenser fan speed control.
Controls feature split capacitor shaded pole motors and are suitable for ganging.
Line voltage accessories.
Identify the speed wires the remaining wires generally capped off with wire nuts are speed wires.
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.
Fan coil relay controls.
I removed the icm and the motor ran fine.
120 208 240 277 480 and 600 vac control.
I replaced a condenser fan motor about a year ago with a oem from trane.
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.
Single or three phase fan speed controllers.
Locate the identification tag for the fan motor which will be somewhere on the fan or motor block.
I had to install a fan cycling control.
By adjusting the condenser fan speed the icm330 controls the airflow through the condenser.
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 fan speed control.
The control monitors the head pressure by sensing the sub cooled liquid line temperature.
Line voltage single phase monitor.
A single desired temperature pressure setpoint adjustment will result in precise.
Install a fan speed control from grainger in a standard wall box for efficient control of ceiling attic kitchen or bathroom fans.
Input output voltage line.
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.
