Flex Fuel Owner’s Manual
Release Mode “acc. to date”
Select release mode “acc. to date” if the furnace should be started on a particular day. The screen “BM
AUTO CONTROL – acc. to date” is shown on the display:
One can now set the exact date and time on which the ignition process should start. The ignition process
always requires a heating circuit demand to be present.
12.5 Activating “Bulk materials auto control”
Once you have filled the furnace with bulk materials and set the required release mode, furnace
operating mode “Bulk materials auto control” can be activated by following the instruction in section 10.
12.6 Status Lines for Operating Mode “Bulk materials auto control”
Boiler is switched off!
Furnace operating mode “Bulk materials auto control” has been set, however the furnace is still switched
off. Press and hold the control knob for 3 – 4 seconds to switch on the furnace.
Bulk materials auto control waiting for time release!
Automatic ignition of the furnace is delayed until the preset time window is active. If the time release is
active, the furnace will automatically start up (automatic ignition).
Availability!
The furnace automatically starts when there is a call for heat and the furnace temperature
is lower than the set “furnace target temperature” less the set “starting difference”.
Automatic ignition!
The furnace will automatically start up (automatic ignition) as soon as a heating circuit demand is
present and a time release has been issued. This will continue until the flue gas temperature exceeds the
factory default flue gas start temperature.
12.7 Automatic Change-Over of Furnace Operating Mode From “Bulk materials auto
control” to “Bulk materials”
The furnace operating mode is automatically changed from “Bulk materials auto control” to “Bulk
materials” when the factory default flue gas start temperature is exceeded. Re-activate operating mode
“Bulk materials auto control” if the material has fully burned and you want to recommence heating in this
furnace operating mode.
Combustion has been completed when the flue gas temperature falls below the factory default
switch-off temperature and the air factor value is above the factory default setting over a long
period (factory default setting 10 minutes). The status then switches to “Stop system!”.
