Troubleshooting Checklist

n

Is the heat generator at the required temperature?

è

Read the heat generator’s thermometer.

n

Is the burner ready?
Is the burner failure lamp on?

è

If necessary, press the sup-

pressor.

n

Was the temperature selector set by mistake?
Setting of the selector knob

P1

n

Check the setting on the control unit.
Setting knobs

B C

and operating mode selector

S

.

n

Is the timer running? Is the displayed time correct?

è

Check the time and switch-on point.

If the problem still has not been solved after checking the settings,
position the setting knob

B

on

+7

The servomotor should now open the mixing valve and the

red

LED

L2

should light up. If this is not the case, the control system

has failed. Contact your heating technician.
