Access Level Required:
ADMIN
Special order R134a chillers are allowed to operate at
higher than standard condenser temperatures. The result-
ing higher operating pressures require higher condenser
warning and safety shutdown thresholds than standard
applications. These chillers are equipped with a special
High Pressure Cutout Switch (HPCO) that can be set to
trip at a higher pressure.
This setpoint allows for either standard or higher tem-
perature condenser temperature operation. It is set at the
factory and requires an ADMIN password to change it. It
is only visible when set to “Extended”. It is set to “Ex-
tended” for those chillers equipped for high condenser
temperature operation. Otherwise, it is set to “Standard”.
For R134a chillers, the thresholds are as follows:
