Push the servo motor onto the rotation axis of the air
regulator lever.
First, align the rotation axis with the air regulator le-
ver so that the servo motor can be pushed on and
simultaneously snaps into place in the motor retain-
ing clamp.

Operation
Function
When the furnace chamber door opens and closes
again, the electronics receives the signal to start a
new combustion cycle.
→
The air regulators open up completely
→
Display = 100 (air regulators open 100%)
If setup to display the air regulator setting.
The
P
or
M
buttons can be used to change between
the fire chamber temperature in °C and the air regu-
lator setting in %.
After approx. 1 minute, the display goes into stand-by
mode to save energy.
Press the
P
or
M
function button to activate it again.
The starting process can be initiated by pressing the
R
button.
After 15 minutes of burning, the air regulator changes
to 50% or 40% depending on the fire chamber tem-
perature that has been reached.
→
The primary air is then shut off completely
→
Display shows 50 or 40
If setup to display the air regulator setting.
The secondary air regulator is shut down gradually to
20% as the combustion cycle continues.
An acoustic signal sounds when 280 °C is reached
and the temperature in the display flashes as a
prompt to "Replenish fuel".
*(Control curve 2+3 = 280°C, Control curve 1 =
200°C)
This prompt to replenish the fuel only serves as ori-
entation information. Depending on the fuel or chim-
ney draught, it is quite possible that it makes sense
to add fuel sooner or later.
When fuel has been added, the control cycle starts
again from the beginning.
If no fuel is added, then the combustion air supply is
completely shut off after approx. 20 minutes.
If a fire chamber temperature of 280 °C is not rea-
ched during the combustion cycle, then the electron-
ics rates the combustion cycle as an abnormal con-
trol procedure. The air regulators remain 100% open.
Only after dropping below 100 °C, will the air regula-
tors close completely in a closing procedure without
any intermediate steps.
If the furnace chamber door is opened during the
combustion cycle or the
R
button is pressed, then a
new combustion cycle is started.
→
The air regulators open completely once again
and the closing process is recalculated
The fire chamber temperature serves as a command
variable. Since it is not measured in the hot gas flow,
it is not to be regarded as the measured flue gas
temperature, but merely as a reference temperature
for controlling the electronics.
Ignition
For ignition, place the fuel as described in the chim-
ney stove's instructions.
The opening procedure of the air regulators is initi-
ated by opening the furnace chamber door and put-
ting in the fuel.
Ignition does not wait until there are glowing embers;
rather the first quantity of fuel is added after approx.
2/3 of the combustion cycle.
If 15 minutes of primary air is insufficient during firing
up, the primary air regulator can then be completely
reopened by opening the furnace chamber door
again or by pressing the
R
button.
