4.6 Safety devices
Heat dissipation
–This function of the boiler control is a safety device
that prevents overheating of the boiler.
–Functioning: If the boiler temperature exceeds the
set Heat dissipation maximum boiler temperature
(in the service menu - General Settings), all pumps
relating to the energy consumer units (e.g. heating
circuit, DHW tank, buffer tank, etc.) will be swit-
ched on and the heating circuit mixer opened. In
this way, energy is drained from the boiler and it
may be possible to prevent other safety devices
tripping.
–If the boiler temperature falls below the set Heat
dissipation maximum boiler temperature minus
1°C again, the pumps and mixers will be operated
in standard mode again.
Operation manual maximus 5

4 Product information
Overtemperature reset (OTR)
The safety temperature limiter (STL) is a safety device
that prevents overheating of the boiler.
Functioning: The STL stops the heating process at a
boiler temperature ~95°C (exclusively electrical func-
tion; fuel and air supply are interrupted).
After tripping, the STL must be manually released
again by unscrewing the black sealing cap 1and pres-
sing the button as soon as the boiler temperature falls
below 60°C.
If the safety overtemperature reset trips, this is indi-
cated in the boiler control display.
Fig. 2-2:Unscrew the closure cap
Thermal overload protection
–The thermal overload protection prevents an uncon-
trolled increase in temperature and pressure of the
boiler.
–Functioning: At a boiler water temperature > 95°C,
the valve opens and directs cold water through the
two series-connected safety heat exchangers.
This lowers the temperature of the boiler and avo-
ids the need for further safety precautions or equip-
ment damage.
Safety valve (to protect against excess pres-
sure in the system)
–The safety valve 1is a safety device for protecting
against overpressure in the water circuit of the hea-
ting system.
–Functioning: The valve opens when the system
pressure exceeds 3 bar. Water/steam are dischar-
ged into an open drain via a discharge line, which
avoids consequential damage to the heating sys-
tem. The valve is closed during normal operation.
–For normative specification see EN 12828.
Fig. 2-3: Safety valve integrated into boiler safety group
EMERGENCY OFF switch
–The EMERGENCY OFF switch is a manually ope-
rated safety device. The burner and the fuel supply
to the boiler are stopped. Circulation pumps remain
in operation to dissipate heat and cool the boiler.
–The switch must be installed outside the heating
room in a safe place that is easy to access.
Temperature monitor in the fuel storage
room (TM)
–Required according to guideline TRVB 118 H for
wood chips, depending on system design, heating
capacity and fuel storage quantity.
–Functioning: On the channel of the fuel delivery
auger, a temperature sensor of a protected design
must be installed in the area of the wall penetration
(inside the storage room). When a temperature of
about 70°C is exceeded, the warning device is
(optically or acoustically)triggered.

Automatically triggered extinguishing
device (ATED)
Fig. 2-4
1 Pocket sleeve for temperature sensor
2 Connection for water discharge
–Functioning: If at the temperature sensor 1the
temperature exceeds 50°C (direct extraction) or 95
°C (downpipe extraction), the valve 2opens and
floods the feeder channel with water.
–This extinguishing device serves to automatically
suppress burn-back within the feeder. Due to the
proper nature and location of the fire detection
element, burn-back must be reliably detected and
the extinguishing device must be triggered instanta-
neously and automatically (this must be ensured
even in the event of a power failure).
–The extinguishing device must be connected either
directly to a pressurised water supply or to a water
reservoir (Note: Domestic waterworks may also be
affected in case of power failure).
–The water supply must be equal to three times the
volume of the feeder equipment, but at least 20
litres. The container must be equipped with a fill
level monitor, including connection to the warning
device (temperature monitor > 6). The extinguis-
hing water inlet opening in the feeder is to be
arranged and executed so that blockage by
delivery operation is not possible and this can
easily be checked at any time. The routing of the
extinguishing system must be made as a non-
combustible version.
–Art. No.: 63260 and 6553
–Specification yes/no see TRVB 118 H
Manually triggered extinguishing device
(MTED)
–This extinguishing device is used to combat a fire
source in the fuel storage room, or fuel storage in
the area of the extraction/delivery line. The trig-
gering must be done manually.
–This device consists of an empty pipe with a mini-
mum nominal size of DN 20 and is to be installed in
the fuel storage as specified by the manufacturer
of the firing system directly above the delivery line
in front of the wall or ceiling passage in such a way
that the greatest possible success can be achie-
ved in extinguishing. The empty piping must be
connected directly to a pressurized water supply
and provided with a shut-off valve arranged in the
boiler room. Mark this valve with a sign "Extin-
guisher - Fuel Storage Room".
–The execution of the extinguishing system must be
done so that damage during fuel feed or from the
extraction device is not possible. In addition, make
sure that the fuel supply to the delivery line is not
affected.
–Specification yes/no see TRVB 118 H.
Rotary valve
The rotary valve fulfils all normative requirements for
the approved fuels regarding fire protection, burn-back
safety, backflow of gases:
Fig. 2-5:Rotary valve
–Complies with requirements regarding burn-back
protection devices (BPD) according to TRVB 118
H.
–Prevents backflow of flammable products of com-
bustion into the fuel supply or into the intermediate
store (according to EN 303-5).
–Prevents spreading of fire into the fuel supply or
into the intermediate store (according to EN 303-5).

Safety switch on the channel cover
Opening the channel cover interrupts the power supply
to the motor of the extraction auger.
4.7 Efficient and low-emission operation
Please note the following recommendations from the
EU Energy Efficiency Directive:
Use of a buffer tank
Since maximum combustion is possible only in stan-
dard operation of the boiler, and greater losses and hig-
her emissions occur during the warm-up and burn-out
phases, use of a buffer tank is recommended.
This tank stores the water heated by the boiler, allo-
wing the connected devices (e.g. heating circuit, DHW
tank, fresh water module, etc.) to access it as requi-
red. This ensures sufficiently long, uninterrupted com-
bustion periods for the boiler.
Use of high-efficiency heating pumps
When using external heating pumps (e.g. return tem-
perature rise, heating circuit pumps, etc.), high-effi-
ciency pumps with energy efficiency class A should
preferably be used.
This delivers savings potential of up to 80 % in drive
energy (compared to conventional heating pumps) with
identical feed results.

2 Feeder unit 6 Ash container 10 Combustion chamber temperature sensor
3 Push grate 7 Rotary drive for primary air 11 Flue gas recirculation line
4 Ash scraper 8 Primary air outlet
Fuel path
–The fuel falls through the rotary valve 1into the channel of the feeder unit 2. The auger delivers the fuel to the
feed grate 3.
–During combustion, the fuel is transported on the feed grate, and the resulting ash falls down through the grate.
–The ash pusher 4push the ashes to the ash auger 5, and auger takes over the transport into the ash box 6.
Airflow
–Primary air is sucked in at the opening 7, forwarded in a space on the left and right side of the boiler; at the holes
8the primary air openings under the combustion grate, and makes it through the feed grate into the combustion
chamber.
–Secondary air is sucked in at the opening 9, and passes through openings in the fire brick (left, right, back) above
the combustion grate in the combustion chamber.
–Flue gas recirculation: If the sensor measures 10 too high a combustion chamber temperature, then flue gas from
the flue gas pipe 11 is introduced here and added to the primary air. This leads to the cooling of the feed grate and
the combustion chamber and thus to lower stress on the components.

De-ashing
–The ashes falling on the feed grate are transported from the transverse ash auger into the ash container 13.
–The ashes falling on electrostatic dust separator 14 are transported forward by the ash auger 15 into the ash con-
tainer.
Flue gas guide
–The flue gas from the combustion chamber flows past the heat exchanger 15, on the electrostatic dust separator
into the flue gas pipe and into the chimney.

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 heating 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).

5.4.5.1 Service menu
In theService menu there are technical (factory pre-
defined) settings for an optimum combustion process
in the boiler. These can only be accessed by qualified
personnel (code input required).
5.4.5.2 IP VNC (for remote access)
The control unit ecomanager-touch allows access to the
control unit screens from a PC or mobile device (e.g.
smartphone). This is effected via VNC (Virtual Net-
work Computing) software. The control has an inte-
grated VNC server, while the VNC Viewer, which is
available free of charge on the Internet, is required for
remote access.
A cable connection is required on site for the connec-
tion of the control unit to the router. Use the Ethernet
socket (type RJ45) on the rear of the control panel
(Touch display).
iInstallation and configuration of this function
must be performed by the customer (i.e. not
included in the commissioning, service and sup-
port activities).
The following points are helpful for setting up a PC/-
router to control the VNC server, which requires know-
ledge of networking technology.

5 Use and operation
IP configuration
►To access the IP-VNC icon, select it in the control
–Selection menu screen
–Customer menu screen
–Trained qualified personnel button
►Enter the data for your router. Recommend pro-
cess:
–Select DHCPON.
ÄThe IP address is determined.
–Select the DHCP OFF + Apply button .
Fig. 2-19.
–The IP address must be unique in each Ethernet
network and is dependent on the other network
components (PC, modem/router, etc.).
–Recommendation: Set a fixed IP address (=DHCP
OFF), i.e. the control unit has a constant IP
address.
Version 1: Installation of VNC viewer for access
from a local PC (PC in the home network)
►Download the free VNC Viewer from the Internet,
install it on the PC and start the application.
►Enter the previously defined IP address of the con-
trol.
–As soon as the VNC Viewer is able to access
the control unit, a password must be entered.
–The password predefined by the manufacturer
is solarfocus
–After login, the screen view of the control unit is
available.
Changing the VNC password
Fig. 2-20
►Press the Change VNC password button on the
IP setup view.
►To change it, first enter the old password, then the
new password, then press the Accept button.
►The new password must be used to log on after
restarting the VNC Viewer on the local PC.
►Press the Reset password button to reset the
password to the default password solarfocus.
Version 2: Installation of VNC viewer for access
from an external PC (PC outside the home net-
work)
–The user's local router does not always have the
same IP address on the Internet (it is allocated by
an Internet Service Provider – ISP).
–Nevertheless, Dynamic Domain Name Systems,
also referred to as DynDNS or DDNS, allows
access to the router.
–These systems allow a unique host name to be
assigned on the Internet; the unique name is then
also entered in the router. If the router is then assi-
gned a different address by the ISP, it enters the
updated IP address as the defined host name on
the DynDNS server. The router and therefore the
home network can then be reached using this host
name.
–To create a connection with the control unit, a port
diversion is required from the external port of the
router[1] to the IP address and to VNC port 5900 of
the control unit.
[1] Port 5950 is recommended
iAvoid any port forwarding from external port
5900 of the router to IP address and VNC port
5900 of the control.
