Note:
The flue cleaning function cannot be started in „solid fuel/buffer mode“. The flue cleaning function must
not be started if an installed solid fuel boiler is operating (heated up). The flue cleaning function may be star-
ted if there is no solid fuel boiler installed or if this is not operating and only the buffer tank is active. In this
case, first set the operating mode switch on the WVF module to relay test 2 or on the BUL module to relay test
1 (see WVF or BUL module operating manual).
Pressing the corresponding menu button enables the boiler to be ope-
rated with 30 % or 100 % output – Fig. 26. The lighting is switched off
after the lighting timer has counted down (10 min); the function or
display remains unchanged. When the button is first pressed only the
lighting is switched on.
When the
Manual operation / flue cleaning function button is pres-
sed again the operating time is reset to 45 min.
