pressure switch-min fails
(terminal X5-01 pin 2 and 3)
Input gas pressure switch-min
If gas pressure switch-min fails, safety shutdown is triggered and startup prevented
until gas pressure switch-min closes again. During start prevention, the yellow LED is lit
and the safety circuit is active. Burner control operates in phase 90.
