2 Safety information
2 Safety information
–Keep unauthorised personnel away: Risk of burns
from hot pipes and components. Do not leave child-
ren unsupervised and check that they cannot
access the boiler.
–If the electrical insulation on cables, plugs, swit-
ches becomes damaged, switch off the voltage
supply and have the insulation repaired. Protect
live parts against moisture.
–If visible damage is found (e.g. leakage of water,
thermal deformation, traces of flue gas or
scorching, mechanical damage, etc.), operation
must not be continued or the boiler started up
again. The system may only be operated if it is in
perfect technical condition.
–If the heating system is out of use for lengthy peri-
ods, it must be ensured that all parts carrying water
are fully protected against frost.
–Never decommission safety devices; should they
fail, have them repaired immediately.
3 Efficient and low-emission ope-
ration
Recommendation of the EU energy effi-
ciency 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.

4.8 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 switched on and the hea-
ting circuit mixer opened. In this way, energy is drai-
ned from the boiler and it may be possible to prevent
other safety devices tripping.
If the boiler temperature falls below the set Heat dis-
sipation maximum boiler temperature minus 1°C
again, the pumps and mixers will be operated in stan-
dard mode again.
Safety temperature limiter
The safety temperature limiter (STL) is a safety device
that prevents overheating of the boiler. Function: The
STL stops the heating process at a boiler temperature
~95°C (exclusively electrical function; fuel and air sup-
ply 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 indicated in the boiler control display.
Fig. 2-1_Position of the overtemperature reset
Thermal overload protection
The thermal overload protection prevents an uncon-
trolled increase in temperature and pressure inside the
boiler. When the boiler temperature is >95°C, it opens
a valve and feeds cold water into the boiler water cir-
cuit to reduce the boiler temperature.
Safety valve to protect against excess pressure in
the system
The safety valve 1is a safety device for protecting
against overpressure in the water circuit of the heating
system. Function: The valve opens when the system
pressure exceeds 3 bar. Water/steam are discharged
into an open drain via a discharge line, which avoids
consequential damage to the heating system. The
valve is closed during normal operation.

group.
Emergency OFF switch (X21)
The emergency OFF switch is a safety device that is
triggered manually (the burner and the burner feed are
switched off).
The switch must be installed outside the heating room
in a safe place that is easy to access.

4.10 Combustion principle
Air conveyance in the heating boiler
The air required for combustion:
–The primary air is sucked through the primary air
flaps 1into the filling chamber 2and exits into the
filling chamber at the point of the primary air ope-
nings 3(small drilled holes, arranged at the bottom
left and right of the filling chamber).
–The secondary air is sucked for the centrally arran-
ged secondary air flap 4, and the air exits into the
combustion chamber 5(i.e. below the stainless
steel combustion grate).
In the combustion chamber, the primary and secon-
dary air mix; this is where the combustion process
takes place (downfiring combustion technology).
The hot combustion air flows through the heat exchan-
ger 6and leaves the boiler through the flue pipe into the
chimney. The speed-controlled ID fan 7on the rear of
the boler sucks the air through the boiler.

5.4.6.2 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 on site (i.e. not included in
the commissioning and service activities).
The following points are helpful for setting up a PC/-
router to control the VNC server, which requires know-
ledge of networking technology.

–Select DHCPON.
ÄThe IP address is determined.
–Select the DHCP OFF + Apply button .
Fig. 2-15_02-031
nThe IP address must be unique in each Ethernet
network and is dependent on the other network
components (PC, modem/router, etc).
nIt is recommended to 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)
nDownload the free VNC Viewer from the Internet,
install it on the PC and start the application.
nEnter 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

nPress the Change VNC password button on the IP
setup view.
nTo change it, first enter the old password, then the
new password, then press the Accept button.
nThe new password must be used to log on after
restarting the VNC Viewer on the local PC.
nPress the Reset password button to reset the pass-
word to the default password solarfocus.
Version 2: Installation of VNC viewer for access
from an external PC (PC outside the home net-
work)
nThe user's local router does not always have the
same IP address on the Internet (it is allocated by
an Internet Service Provider – ISP).
nNevertheless, Dynamic Domain Name Systems,
also referred to as DynDNS or DDNS, allows
access to the router.
nThese 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.
nTo 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.

6.1 Preparations for the operating type.
Combustion grate
►Use this stainless steel combustion grate to heat
with log wood.
Fuel to be used
1Dry, easily combustible small piece of material
(e.g. small chopped logs, wood shavings, bush
wood chips).
2Split logs, medium-sized, dry
(recommended:0.5 m lang).
3Split logs, large, dry (recommended:0.5 m
long).
Select operating mode and start
►Select the Log wood operating mode and press
the Start button.

iStarting in Logs mode is possible only in the
status Burner switched off or Log burning is ter-
minated.
6.2 Stack the log wood in the filling cham-
ber and ignite
Basic information:Stack the log wood parallel to the
side wall of the boiler, in the filling chamber.
iNote regarding therminator-II 49 and
60:Due to the wide filling chamber, the space
can be better used if the log wood is stacked
transversely in the filling chamber.
►Stack the smaller pieces of wood 1and 2parallel
to the side wall of the boiler high enough that the
floor of the filling chamber is covered.

►Set up and ignite one layer of igniting material
(e.g. kindling, wood waste splits).
►When the kindling is burning, add a layer of
medium-sized log wood 2on top.
►Fill the boiler with log wood 3in accordance with
the temperature in the buffer tank, or the current
heat needed.
►Close the filling chamber door.
ÄThe residual oxygen content in the flue gas
(value is visible on the display) should fall
quickly.

6.3 Replenish with logs
►Before adding more wood, check whether suf-
ficient energy dissipation is ensured by the con-
sumer units (heating circuit, buffer tank, etc.).
Icon for Add more log wood
The icon indicates that more log wood needs to be
added (appears in the main screen > 11).
When the icon is displayed:
Option 1 - the boiler is currently burning log wood
(active burning):
–A heating request is pending on the boiler (from
connected devices, e.g. heating circuit, DHW
tank, buffer tank, etc.)
–And: the burn duration is> 2 hours
–And: the measurement parameter for exhaust tem-
perature and residual oxygen content indicate upco-
ming completed combustion.
Option 2 - boiler is switched off (STOP mode), or Log
wood combustion is completed status:
–If there is a heating request on the boiler.
End of burning
The combustion period that has passed so far is
shown in the boiler control display. The combustion
period differs depending on log wood quality and boiler
performance.
The boiler stops combustion, if
–the flue gas temperature falls below the Exhaust
cutoff temperature.
–the residual oxygen content in the flue gas
exceeds a predefined value for a long period of
time.
ÄMessage on the status line: Burn-off logs finis-
hed.

6.4 Glow holding function
iFunction must be activated by qualified per-
sonnel.
The log wood located in the filling chamber has not
been fully combusted. The embers or charcoal that
remain in this way can easily be re-ignited (manually or
automatically by the hut air blower).
Figure:Unburned, charred log residue after burning
with glow holding.
nThe time to wait between switching off glow hol-
ding and repeated ignition is unimportant. What is
important for straightforward ignition is the pre-
sence of the charred log wood residue.
nEach time the heat-up process is performed, you
will be asked whether you would like to start burn-
off with or without glow holding.

Manual ignition after combustion with Glow hol-
ding
►Push the charred pieces together on the stainless
steel combustion grate using the poker.
►In the boiler control, select the Log wood operating
mode and press the Start button.
►Ignite a sheet of paper and let it fall, burning, into
the filling chamber (the flame is sufficient to ignite
the rest of the material).
►Wait for a moment until the rest of the material is
visibly burning.
►As described above, add more log wood and close
the filling chamber door.

the next ignition process.
iRecommendation for your first (three to four)
ignition attempts with the automatic log wood
function:Only fill the boiler filling chamber with
log wood once ignition has been performed suc-
cessfully. This means that you will not have
clear out all of the filled material if you have a
failed attempt at ignition.
