Air pressure differential sensor fault during pre-ventilation (after 4
restarts).
Check the following:
- Is the air pressure differential switch defective
- Has the wiring short circuited
- Check for signs of external thermal draught in the flue gas discharge
duct.
Check:
- The heating pump is operating
- There is sufficient water flow through the boiler
- The water pressure is > 0.8 bar.
Short circuit of boiler block sensor.
Boiler shut-off sensor not connected or defective.
Check:
- The heating pump is operating
- There is sufficient water flow through the boiler
- The water pressure is > 0.8 bar.
Proceed as follows with all non-listed codes:
- Press reset once
