FEATURES
Temperature The microprocessor maintains the set supply Chilled Water temperature by sensing the
return and supply water temperatures, compressor loading.
The microprocessor also monitors and displays the following measured parameters:

Supply Water Temperature

Return Water Temperature

Suction Pressure of each circuit

Liquid Pressure of each circuit

Suction Temperature at each circuit

Superheat for each circuit
Alarms The following conditions will be detected, triggering a visual display:
Common for both circuits:

Low Supply Temperature

Emergency Stop

Water Flow
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 Switch

Compressor Overload

High Compressor Discharge Temperature
Networking A Local Area Network ( ) can be used to connect a number of chiller controllers to
offer intercommunication and sequence control. This also allows the connection of
computers, printers and modems on the same communications ring. For further details
