2.6.6 Chimney sweeper function
This function aids the performance of legally-required
emissions testing.
Note!
The chimney sweeper function cannot be started in “solid
fuel/buffer mode”. The chimney sweeper function must
not be started if an installed solid fuel boiler is operating
(heated up). The chimney sweeper function may be star-
ted if there is no solid fuel boiler installed or if this is not
operating but only the accumulator tank is active. In this
case, first set the operating mode switch on the WVF+ to
relay test 2 or on the B-PLM+ to relay test 1 (see WVF+ or
B-PLM+ operating manual).
A short press of the
Manual operation/chimney
sweeper function
button switches on the lighting and
display. Pressing the button again starts the chimney
sweeper function – Fig. 24. The boiler temperature is
set to approx. 60 °C for 45 minutes.
Pressing the corresponding button enables the boiler
to be operated with 30 % or 100 % output – Fig. 25. The
lighting is switched off after the lighting timer has coun-
ted down (10 minutes); the function or display remains
unchanged. Only the lighting is switched on when the
button is first pressed.
The operating time is reset to 45 minutes. when the
Manual operation/chimney sweeper function
button is
pressed again.
The chimney sweeper function ends
– when the
Cancel
button is pressed – Fig. 26.
– automatically after about 45 minutes.
