Checking the thermocouple

If the burner control unit cannot be
reset after a fault shutdown, although
the boiler water temperature is below
approx. 90 °C:

Pull the leads from
thermocouple

Check the continuity of the thermo-
couple with a multimeter.

Remove the faulty thermocouple.

Install a new thermocouple.

After commissioning, press reset
button

on the control unit.

Checking and replacing pressure differential sensor

Check the sensor in case of fault messages concerning the differential pressure
sensor:

correct installation

electrical connection

correct position of the O-rings inside the adaptor

are the test nipples closed with plugs?

Replace the sensor if fault messages persist.
