Design Features & Information
FEATURES
Temperature
The microprocessor maintains the set supply Chilled Water temperature by sensing the
return and supply water temperatures and manages the compressor loading.
The microprocessor also monitors and displays the following measured parameters:
Supply Chilled Water Temperature
Return Chilled Water Temperature
Return Condenser 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
