Pressing one of the six buttons switches the lighting and display on.
Manual operation starts if the Manual operation / flue cleaning func-
tion button is pressed for more than five seconds – Fig. 21. This sets
the boiler temperature to the setpoint fixed for manual operation
(standard value 60 °C). The control system is not affected by this. The
lighting is switched off after the lighting timer has counted down
(10 min.); the function or display remains unchanged.
Note:
Manual operation cannot be started in „solid fuel/buffer mode“. Manual operation must not be started if
an installed solid fuel boiler is operating (heated up). Manual operation may be started 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 modu-
le operating manual).
