If a fire chamber temperature of 100°C is not reached
during firing up after 10 minutes, the air regulators
close completely again.
Attention:
The fire grate must normally be open during heating,
otherwise no primary air can enter into the fire cham-
ber.

Shortened or extended combustion cycle
Since the operation of the chimney stove is primarily
dependent on the downstream chimney, you have
the possibility of reacting to different chimney condi-
tions by choosing different control curves.
Control curve 1:
→
Extended combustion cycle
→
Use, for example, with increased chimney
draught
→
Primary air shuts off after 10 minutes
→
Reduced secondary air supply
→
"Add fuel" signal if temperature drops
below 200 °C
Control curve 2:
→
Normal combustion cycle (factory setting)
→
Primary air shuts off after 15 minutes
→
"Add fuel" signal if temperature drops
below 280 °C
Control curve 3:
→
Reduced combustion cycle
→
Use for poor chimney draught
e.g. transition times with increased
outside temperatures
→
Primary air shuts off after 20 minutes
→
Increased secondary air supply
→
"Add fuel" signal if temperature drops
below 280 °C
Furthermore, there is the possibility of setting the
shut-off time of the primary air in a range of 5 to 60
minutes for the electronics in the operator menu.
