5.6.14 High Pressure alarm
This alarm is generated in case the Condensing saturated temperature rise above the Maximum condensing saturated
temperature and the control is not able to compensate to this condition. The maximum condenser saturated temperature
is 68.5°C but it can decrease when the evaporator saturated temperature become negative.
In case of water-cooled chillers operating at high condenser water temperature, if the Condensing saturated temperature
exceeds the Maximum condenser saturated temperature, the circuit is only switched off without any notification on the
screen as this condition is considered acceptable in this range of operation.

Solution
Circuit status is Off.
