FEATURES
Temperature The microprocessor maintains the temperature by sensing the return air temperatures
and manages the compressor loading.
The microprocessor also monitors and displays the following measured parameters:

Liquid Pressure of each circuit
Alarms The following conditions will be detected, triggering a visual display:
Common for both circuits (Dual Circuit units):

Phase Rotation (Optional)

Emergency Stop
Individual for each circuit:
Individual alarms will isolate the affected circuit only.

Compressor Trip

Low Suction Pressure for each circuit

High Liquid Pressure for each circuit

Volt Free Contact Alarm Indication

Low Pressure Cut-out

Compressor Overload

High Compressor Discharge Temperature
