10 Troubleshooting

10.1 Procedures for fault conditions

The combustion manager recognises irregularities of the burner and displays these
on the display and operating unit.

The following conditions can occur:

Display off [ch. 10.1.1],
Display OFF [ch. 10.1.2]
Display flashes [ch. 10.1.3].

10.1.1 Display off

The following faults may be corrected by the operator:

Fault

Cause

Rectification

Burner not operating

External fuse has tripped

Check fuse.

Heating switch is set to Off

Switch on heating switch.

Temperature limiter or pressure limiter
on heat exchanger has triggered

Reset temperature limiter or pressure
limiter on heat exchanger.

Low water safety interlock on heat ex-
changer has triggered

Top up water.
Reset low water safety interlock on
heat exchanger.

Notify your heating contractor or Weishaupt Customer Service if the problem occurs repeatedly.

10.1.2 Display OFF

The following faults may be corrected by the operator:

Fault

Cause

Rectification

Burner not operating

Temperature regulator or pressure regu-
lator on heat exchanger has been set in-
correctly

Adjust temperature regulator or pres-
sure regulator on heat exchanger.

Boiler or heating circuit control is not
functioning or has not been set correctly

Check function and setting of boiler
or heating circuit control.
