Hi All. I have 30RQ120 Chiller with AquaSnap Control System.
In cooling mode, the unit is working fine.
In the heat pump:
1. The unit starts up and gets into position EXV 27% and off for high pressure
EXV on the sensor does not respond - only 27%
I heated the sensor - no reaction - 27%
and off for high pressure
In what could be the reason?
Thanks in advance for your help
