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 Water Temperature

Return Water Temperature

Suction Pressure of each circuit

Liquid Pressure of each circuit

Suction Temperature at each circuit (when the EEV option is fitted)

Superheat for each circuit (when the EEV option is fitted)
Alarms The following conditions will be detected, triggering a visual display:
Common for both circuits (Dual Circuit units):

Low Supply Temperature

Emergency Stop

Water Flow

Pump(s) status

Pump(s) remote start
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. There is also the facility to allow the
connection of either a computer or modem for local or remote monitoring.
