18. Solid fuel/ buffer mode

If the pellet boiler is combined with a solid fuel boiler or a buffer, the buffer load function module automatically switches
over between pellet and solid fuel/ buffer mode.
Combustion of the pellet boiler is stopped when the buffer load function module sends the request to switch over to
solid fuel/ buffer mode – Fig. 58.
Following this, the system switches over to solid fuel/ buffer mode and the pellet boiler is locked – Fig. 59.
If the pellet boiler is switched off using the ON/OFF button on the InfoWIN Touch, an automatic switch-over to solid
fuel/ buffer mode is performed in conjunction with a buffer load/switching function module. Once the InfoWIN Touch
unit is switched on, the pellet boiler may be locked out for a maximum of 15 minutes due to switch-over delays. This is
indicated in the InfoWIN Touch with "Burner locked" – Fig. 59.
After 12 minutes in solid fuel/ buffer mode, the display is switched off completely. When the InfoWIN Touch is touched,
the display turns back on again.
