Operation
2.5.4 Solid fuel/buffer mode
If the FireWIN pellet central heating boiler for living areas is combined with a
solid fuel boiler or an buffer tank, the WVF or BUL module automatically swit-
ches over between pellet and solid fuel/buffer mode.
Combustion of the FireWIN is stopped when the WVF or BUL module sends
the request to switch over to solid fuel/buffer mode – Fig. 19.
Following this, the system switches over to solid fuel/buffer mode and the Fire-
WIN burner is locked – Fig. 20
If the pellet central heating boiler for living areas is switched off using the
ON/OFF button on the InfoWIN, an automatic switchover to solid fuel/buffer
mode is performed in conjunction with a WVF module. Once the InfoWIN unit
is switched on, the pellet central heating boiler may be locked for a maximum
of 15 minutes due to the switch-over delay. This is displayed by InfoWIN –
Fig. 20.
After an hour in solid fuel/buffer mode, the display is shut down fully and only
the green LED is lit up. The display is switched back on by pressing a button
or when there is a heating requirement.
