Differential Pressure Switch Alarm
This error seems to occure randomly and we are not sure yet, what the issue is.
Problem: Differantial Pressure Switch Alarm on screen
It means differential pressure between high pressure side and low pressure side is not correct.
This usually happens when there are excessive temperature differences or when the compressor does not have enough power.
Solution:
Please restart the system and check the compressor pipes and the evaporator to see if it is completely frozen.
