Errors


Boiler type FS-120LP

Error code FAULT 37 =

Cause:

The water pressure in the CH installation is too low

Solution:

Low water pressure error can be caused by the low water pressure in the central heating system. This can be detected in 2 ways: via low water pressure switch and via water pressure sensor ( with a confirming time of 10 seconds). In error mode, the heat demand and the pumps are switched off. See Pressure supervision of the central heating installation paragraph
