McQuay inverter hp chiller

[waseem naamo]

Dear All

I have a problem with chiller made by McQuay
Air cooled - inverter - heat pump

the problem : chiller did not stop at outlet water temp setpoint ( 7 C ) , it is still working down to antifreeze setpoint ( 3 C )

Please advise asap

Recalibrate thermostat to switch at correct point.

Hi
check what sensor is set to regulate your water temp.
ewt or lwt , the sensor could be out of cal as brian said or your settings are wrong.
good luck

water sensors are calibrated , i set it as water leaving temp
the problem that 3 units have same fault ????
