How combi mode works

Switching off the boiler

3.3.6 Regulating the boiler

30
The boiler is controlled as a system with automatic feed in combi mode. The boiler is
ready for operation as soon as it is switched on and automatically starts combustion
when heat is required or at a set starting point. If there is firewood loaded at this time,
the firewood is ignited by pellet burner. If the firewood has burnt out, pellets are
automatically used to continue heating depending on the heat requirements.
Heating with firewood in combi mode:
❒ Open insulated door
➥ If the door is opened in pellet mode, wait approx. 5 minutes for the pellet unit to
shut down to prevent flue gas from escaping when you open the fuel loading
chamber door
❒ Open the fuel loading chamber door and fill according to output
Heating the boiler with firewood
NOTICE! If the firewood is to be ignited by the pellet burner, ensure when filling the
firewood boiler that a piece of firewood is inserted diagonally on top of the first layer to
allow air to flow freely up to the burn-out opening. Instead of a diagonal piece of
firewood, you can use a layer of cardboard which should be inserted in such a way
that the flame has a direct path to the burn-out slot of the firewood boiler.
❒ After loading, the fuel can be lit manually, or automatically by the pellet burner
later on when heat is required
❒ Press the standby key
➥ The boiler follows the shutdown program and switches to "Off" status
➥ The combustion unit is switched off, the chamber discharge unit and the entire
hydraulic system remain active
❒ Switch the boiler off by tapping "Pellet unit Off"
➥ The boiler follows the shutdown program and switches to "Off" status
➥ The combustion unit is switched off, the chamber discharge unit and the entire
hydraulic system remain active
Please see the relevant operating instructions for the "Lambdatronic SP 3200" boiler
controller for the necessary control steps, as well as displaying and modifying
parameters
