Firewood start I
Upon elapse of the 'Hybrid start' the furnace switches to this operating phase. Here it is en-
sured that all pellets combust in the combustion bowl and that the firewood continues to
be inflamed.
If the firebox door is opened and closed again when the stove is idle (and the question
"Have you inserted firewood?" is answered with "Yes" on the display), the stove also
changes to the operating status "Firewood start I".
In this operating phase, all air dampers are fully open and the flue gas fan rotates at a given speed. After at-
taining a specific firebox temperature and the elapse of a specific time, a switch to 'Firewood start II' is per-
formed.
If no temperature increase is detected, the stove automatically switches to the 'OFF'
state again. However, the stove remembers that firewood has been inserted. (A small
green icon appears on the display.) After the next pellet ignition, the stove automatically
switches over to 'Hybrid start'.
Firewood start II
In this operating status, the riddling grate is opened after approx. 2 minutes. As a result,
the primary air damper is closed and the firewod continues to be fanned until a certain
temperature in the firebox is reached (depending on the selected heat output). Once
this temperature has been obtained, the stove switches to the status "Firewood mode".
Firewood mode
In this operating status, the stove automatically controls combustion of the firewood.
Depending on the output setting, the stove will attempt to maintain a specific firebox
temperature. If this cannot be achieved, automatic switching to the next lower output
level is performed in the background (not visible on the display). This achieves optimal
combustion and ember maintenance of maximum duration in the burn-out process.
Power setting 1 is not suitable for burning newly inserted firewood.
This level is intended only for the purpose of achieving maintenance of the embers for as long as pos-
sible.
If the heat output is changed on the display, the combustion control is restored to the preset output.
If you change the heat output on the display, the combustion control is reset to the output setting.
If the firebox door is opened and closed again, the query 'Have you inserted fire-
wood?' is shown on the display.
If you answer this with a 'Yes', a switch back to the status 'Firewood start II' is performed.
This ensures the lighting-up of the new firewood.
If you answer this with a 'No', the stove remains in firewood mode status. Automatic con-
trol is continued without having to light new firewood.
If no further firewood is put on, the stove automatically switches to burn-out and finally closes the dampers.
If the stove is not yet turned on at this point in time and the room temperature setting has not yet
been attained, the stove will start automatically again in pellet mode.
Firewood mode with non-electrical operation
In an emergency the stove can be heated with firewood, without any electricity. In this emergency mode, the
secondary damper is fully open at all times. Manual control is not possible.
