MONITORING The microprocessor also monitors and displays the following measured parameters:

Supply Water Temperature

Return Water Temperature

Evaporator Inlet water temperature

Ambient Air Temperature

Suction Pressure of each circuit

Liquid Pressure of each circuit

Suction Temperature at each circuit

Superheat for each circuit
ALARM HANDLING The controller logs and allows viewing of the last 100 conditions recorded in descending
chronological order through the keypad display.
The following conditions will be detected, triggering a visual display:
Common for both circuits:

Low Supply Temperature

Mains Phase Failure / Phase Rotation

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

Isolator Status

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. For further
details, please contact Airedale.
CAUTION When adding to an existing network, please consult Airedale to ensure
strategy compatibility.
