2.6.5 Manual operation
Note!
Manual operation cannot be started in “solid fuel/buffer
mode”. Manual operation must not be started if an ins-
talled solid fuel boiler is operating (heated up). Manual
operation may be started if there is no solid fuel boiler in-
stalled 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).
Pressing one of the six buttons switches the lighting
and display on. Manual operation starts if the
Manual
operation/chimney sweeper function
button is pressed
for more than five seconds – Fig. 20. This sets the boiler
temperature to the setpoint fixed for manual operation
(standard value 60 °C). The current automatic setting
is not affected by this (see also section 2.10). The ligh-
ting is switched off after the lighting timer has counted
down (10 minutes); the function or display remains un-
changed.
Pressing the
Cancel
button terminates the function –
Fig. 21. The boiler returns to automatic operation.
Setpoint adjustment for manual operation
By pressing the – or + button the display switches to
the setpoint adjustment mode – Fig. 22. Using the – or
+ button can change the setpoint in 1 K steps. The tem-
perature set in this mode is not permanently saved. The
original set temperature is used once manual operation
ends.
After pushing the
Back
button (Fig. 23) or after waiting
10 minutes, the screen returns to its previous display.
