Operation

2.5.3 Pellet feed

Pellet feed – burnout
Pellet feed from the storage room into the reserve supply container has been
requested. Combustion is stopped. Pellet transport into the burner pot is
stopped, the Induced draught fan continues to run until all the remaining pel-
lets have been burned and the burner pot has cooled down – Fig. 12.
Pellet feed in operation
The pellet feed is in operation. Pellets are supplied from the storage room into
the reserve supply container. The burner is locked – Fig. 13.
2.5.4 Solid fuel / buffer mode
If the BioWIN pellet boiler is combined with a solid fuel boiler or an accumu-
lator tank, the WVF or BUL module integrated in the control panel automati-
cally switches over between pellet and solid fuel/buffer mode.
Combustion of the BioWIN is stopped when the WVF or BUL module sends
the request to switch over to solid fuel/buffer mode – Fig. 14.
Following this, the system switches over to solid fuel/buffer mode and the
BioWIN burner is locked – Fig. 15.
If the pellet boiler 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 boiler
can be locked out for a maximum of 15 minutes due to switch-over delays.
This is displayed by InfoWIN – Fig. 15.
After an hour in solid fuel/buffer mode, the display is shut down fully, only the
green LED is lit up. The display is switched back on by pressing a button or
when there is a heating requirement.
