OPERATING SETTINGS FOR THE ELECTRONIC CONTROLLER
All work on the chiller may only be carried out by specialist personnel!
The chiller is supplied pre-adjusted for normal operating conditions and normally does not require any modifica-
tions, except for the setting the temperature of the cooling medium to the desired value. Checking and any possi-
ble adaptation of the operating parameters is carried out via the controls on the front of the chiller and via the co n-
trol panel. The chillers are equipped with an operating thermostat to maintain the cooling medium te mperature at a
constant value. The various models may be equipped with two types of operating thermostats:
