5 Use and operation
i
Domestic hot water heating in summer
If the boiler s used for heating domestic hot
water, then the required chimney pull 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
head (greater than 30°C); as a result the cooler
air does not rise (~ 20°C air temperature when
the burner starts) in the chimney.
Remedy: Set the burner time release from
00:00 to 07:00 or from 21:00 to 23:59.
Burner release outdoor 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 suction
extraction, i.e. the suction turbine cannot start. (e.g.
for manual filling of the intermediate pellet store
through the inspection flap
5
).
DANGER
- Pellets falling down next to the con-
tainer
6
may remain on the top side
7
of the pel-
let burner. Risk of uncontrolled ignition.
►
Avoid pellets falling down, e.g. use a stain-
less steel hopper when filling.
►
Remove pellets, which have fallen down,
from the top side of the pellet burner (the
cover on the front of the boiler must be
removed in order to do this).

Optional, i.e. the button of the same name and the
screen are only visible when if this item has been obtai-
ned.

Probe switching
8
Automatic
(recommended setting): After three suc-
cessful suction procedures at a probe, the system swit-
ches to the next probe. An even reduction of the level
in the pellet storage area is achieved.
Selectively
: the probes are successively sucked
empty.
Only probe
….: suction is performed without exception
at the preset probe. Switching to the next head must
be performed manually at the control.
