the embers, the combustion chamber can be ventilated by opening the com-
bustion air for three minutes. This function allows the ember bed to reduce
further. After the venting process, the combustion air
is closed completely (0%) and the control shifts to standby mode (control
display off).
The correct operation of the S-Thermatik mini combustion control is indi-
cated by a maintenance-free signal lamp that is mounted behind the fire
symbol in the bottom flap and is displayed by the moving air adjustment
lever.
If the air adjustment lever does not move after opening the combus-
tion chamber door, the S-Thermatik Mini must be switched to man-
ual mode by hand using the mechanical unlocking device (rocker
switch). The selector switch is located in the supply air box and can be
seen when the front cover of the stove is opened. The combustion air
can be adjusted by hand via the air adjustment lever. Further details
on manual setting can be found in 4.1.1 Combustion air regulation.
The fireplace insert must never be put into operation with the
combustion air supply (combustion air lever all the way to the left)
closed!
Heat-up errors and the prompt for adding fuel are indicated by an audible
signal. The acoustic signal can be switched off using the rocker switched
mounted on the control housing.
3.2.2 FUNCTIONAL TESTING OF THE S-THERMATIK MINI
When commissioning the control each time (inserting the wall plug transformer
into the socket or when shifting the selector switch from manual to automatic),
this carries out a self test when the combustion chamber door is closed. In doing
so, the air adjustment lever moves from the left to the right and after a rest period
of max. 1 minute, back to the left again. The air adjustment lever only moves to
the left if the door contact and the flue gas temperature sensor are functional. The
self test should be carried out when the combustion chamber is cold. When the
combustion chamber is hot, the air adjustment lever does not move completely to
the left, it takes the respective position according to the current flue gas tempera-
ture. After this self test, the control shifts to stand-by mode with cold stoves and
"waits" until the combustion chamber door is opened.
Perform self-test:
•
Move the selector switch to manual
•
Insert the wall plug transformer into the socket
•
Position the air adjustment lever in the middle by hand (about 50%)
•
Move the selector switch to automatic
