The restoking alarm
When the combustion progresses to the ember phase, a restoking alarm will go off.
The alarm will light up three times with a ten second interval and it is supported
by sound.
Three different amounts of wood are recommended for restoking:
A small amount of wood (1000 - 1600 g)
A medium amount of wood (1400 - 2200 g)
A large amount of wood (2000 - 3600 g)
You must use at least two pieces of firewood at a time, even if you only want to use
a small amount of wood. The temperature causes the wood to gasify. Two pieces of
firewood heat up each other and increase their temperature faster.
A reminder of the restoking alarm
If a restoking alarm has gone off, and no restoking has been carried out, this symbol
will flash on and off in the upper left corner.
If the symbol has been displayed for a long time, the temperature in the flue gasses
can be so low that you have to light up again in order to give the stove more air
(this is done by pressing the remote control twice, causing the lighting up symbol
to appear in the display).
Always be aware that the status line changes from the burning out phase to the
combustion process phase when the stove is relit. Thereby you ensure that the
stove has registered that you have added new firewood which requires an adequate
amount of air. The oxygen level in the combustion compartment increases when
the door is opened. This sends a signal to the stove that new firewood has been
added to the fire. Towards the end of the burning out phase, the oxygen level in the
combustion compartment can be so close to the oxygen level in the room that the
increase in the oxygen level in the combustion compartment due to the opening
of the door cannot be registered. If, shortly after relighting, the status line does not
alter from burning out phase to combustion process phase, you should press the
remote control twice until the lighting up symbol (the matchbox) appears.
Updating
When the Air box is updated with new software (by a service technician), this will
be displayed graphically.
Advanced menu
The remote control has a menu in which more advanced settings, etc. can be changed.
By pressing the button on the remote control for more than five seconds, you get
into the advanced menu:
These are the main menus:
• Sound (turn the sound on and off)
• Self-test (initiate the "Self-test", for instance when a service technician visits)
• System info (which version of the software is in the Air box and in the remote
control respectively)
• Link to stove (should be applied when a remote control is matched with an Air
box. This should be done at the factory)
