Circuits are always started and stopped to guarantee the balancing of running hours and number or starts in
multiple circuits units. This strategy optimizes the lifetime of compressors, inverters, capacitors and all the
others circuit components.
5.1.4 Alarm Settings
If glycol is present in the water circuits, factory defaults values for the Alarm Limits listed below must be adjusted:
Parameter
Description
Low Press Hold
Set the minimum refrigerant pressure of the unit. It is generally recommended to set to a value whose saturated
temperature is 8 to 10°C below the minimum active setpoint. This will allow a safe operation and a proper control
of compressor suction superheat.
Low Press Unload
Set lower than the hold threshold enough to allow a suction pressure recovery from fast transients without
unloading the compressor. A 20 kPa differential is generally appropriate for most applications.
Evap Water Frz
Stops the unit in case the leaving temperature falls below a given threshold. To allow a safe operation of the
chiller, this setting must be adequate to the minimum temperature allowed by the mixture water/glycol present in
the evaporator water circuit.
Cond Water Frz
Stops the unit in case the leaving temperature falls below a given threshold. To allow a safe operation of the
chiller, this setting must be adequate to the minimum temperature allowed by the mixture water/glycol present in
the condenser water circuit.
When glycol is used in the plant, always disconnect antifreeze electric heater.
