Domestic hot water heating in summer
If the boiler is used for heating domestic hot
water, then the required chimney draught of 5
Pa may not be present in the summer months
(or outside the heating period). This may
result in smoke escaping in the boiler room.
Reason: High temperature on the chimney
stack (greater than 30°C); as a result the coo-
ler air does not rise (~ 20°C air temperature
when the burner starts) in the chimney.
Remedy: Set the burner release time from
00:00 to 07:00 or from 21:00 to 23:59.
Burner release outside temperature
2
The burner may not start if the outside temperature
exceeds this value.
External boiler release
3
On
switches the function to standby. I.e. a connected
external boiler may only start when it receives the
release from the SOLARFOCUS boiler (e.g. on the
basis of a lack of fuel, operating fault).

Release
1
Within the release times, the pellet suction turbine
can start. A release time from 00:00 to 23:59 means
that no restriction is pending and suction can start at
any time.
Intermediate pellet store filling
2
Pressing the button starts the suction turbine and the
tank is filled once. (i.e. current level and release times
are not considered). Prerequisite: the boiler must
have the status
Switched off
or
Standby
.
Manual filling
4
Pressing the button deactivates the automatic
vacuum output, i.e. the suction turbine cannot start.
(e.g. for manual filling of the intermediate pellet store
through the inspection flap).
Automatic diverter for suction heads
3
Optional, i.e. the button of the same name and the
screen are only visible if this item has been bought.

Probe switching

Automatic
(recommended setting): After three suc-
cessful suction procedures at a head, the system swit-
ches to the next head. An even reduction of the fill
level in the pellet storage area is achieved.
Selectively
: The heads are successively sucked
empty.
Only probe
….: Suction is only performed at the set
head. Switching to the next head must be performed
manually at the boiler control.
Storage area filled

–
Pressing the button marks all suction heads
10
again as full (e.g. after filling the storage area).
Pressing the Status button changes the head sta-
tus (colour red: Head is empty; colour
green: Head is full).
–
Red marking means: Head is sucked empty.
–
Green marking means: Head is full.
–
The arrow

above the heads shows the
currently used head. Position
C
means that the pel-
let hose has been sucked empty (happens auto-
matically, lasts a few seconds).
