4.7 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.
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. 2-1: Position of the overtemperature reset
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. 2-2: 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 boiler
room in a safe place that is easy to access.

4.9 Efficient and low-emission operation
Please note the following recommendations from the
EU Energy Efficiency Directive:
Use of a buffer tank
As the most complete combustion of wood pellets is
possible only when the boiler is in normal operation
and as greater losses and higher emissions occur
during the warm-up and burn-out phases, the 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.

5 Use and operation
iDomestic 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).
5.4.2 Vacuum output
Fig. 2-9: Vacuum output
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).
Automatic suction probe switch unit 3
Optional, i.e. the button of the same name and the
screen are only visible when if this item has been obtai-
ned.
Fig. 2-10
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.
Storage area filled 9
nPressing the button marks all suction probes 10
again as full (e.g. after filling the storage room).
Pressing the Status button changes the probe sta-
tus (colour red: Head is empty; colour green:Head
is full).
nRed marking means: Probe is suctioned empty.
nGreen marking means: Probe is full.
nThe arrow 11 above the heads shows the currently
used head. PositionCmeans that the pellet hose
has been suctioned empty (happens automatically,
lasts a few seconds).

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 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.
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. 2-16
–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 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.
5.4.6.3 Sending e-mails
Function: The boiler control ecomanager-touch auto-
matically sends status e-mails and alarm e-mails (to
stored addresses) if required.
Status e-Mail: An automatic e-mail (e.g. sent daily) pro-
vides information on the current boiler status.
Alarm email: a message is sent when a fault occurs.
iInstallation and configuration of this function
must be performed by the customer (i.e. not

6.1.1 Heating circuit operating mode
Heating mode
The heating circuit pump is activated. A shutdown
occurs whenever
–the external shutdown temperature for heating
mode is reached
–when a room temperature sensor is used and
where room nominal temperature for heating mode
has been reached.
The heating circuit is supplied with the calculated inlet
nominal temperature > Fig. 2-25.
Reduced mode
Heating circuit pump is activated. A shutdown occurs
whenever
–the external shutdown temperature for reduced
mode is reached.
–a room temperature sensor is used and where
room target temperature for reduced mode has
been reached.
The heating circuit is provided with the reduced tem-
perature, i.e. calculated inlet nominal temperature
minus reduction;> Fig. 2-25.

6 Heating circuit
Time switching
In this operating mode, the timed switch-over between
Heating mode and Reduced mode is defined. You can
enter the times for heating mode Daily or In blocks.
Usage example: Heating mode should be active during
the day, but be changed to reduced mode at night.
Switch off heating circuit
The heating circuit pump and heating circuit mixing
valve are switched off. The anti-freeze function for the
heating circuit is enabled (i.e. the heating circuit pump
is switched on whenever the ambient temperature
drops below the anti-freeze temperature).
Holiday mode
Holiday mode deactivates the active operating mode
for the entered duration.
activates the frost protection mode for the hea-
ting circuit for the duration of the holiday.
activates the reduced mode for the heating cir-
cuit for the duration of the holiday.
This icon indicates an activated holiday mode in
the heating circuit screen.
6.1.2 General settings
Cutoff temperature
If the outdoor temperature exceeds the value set here,
the heating circuit pump is switched off and the hea-
ting circuit mixer closes.
Cutoff temperature for heating mode: 18°C
Cutoff temperature for reduced mode: 5°C
iThis means: the heating circuit is normally auto-
matically switched off during the summer
month due to the outdoor temperature.
You can also switch the heating circuit off
manually (=operating mode: Switch off heating
circuit).
Anti-freeze temperature
If the outdoor temperature drops below the value set
here, the heating circuit pump is switched on.
Buffer difference
The burner starts when the tank temperature top falls
below the required flow temperature minus the buffer
difference.
Example:
- Current flow required temperature = 50°C
- Buffer difference = 5°C
The burner starts as soon as tank temperature top <
45°C.
A negative buffer difference value is added, i.e. the bur-
ner starts earlier.
Example:
- Current flow required temperature = 50°C
- Buffer difference = - 5°C
The burner starts as soon as tank temperature top <
55°C.
Ext. temperature delay
The delay set here is used to determined an average
value for the outdoor temperature (= Average outdoor
temperature).
The heating circuit pump switches on if the Average
temperature and the Current outdoor temperature fall
below the cutoff temperature (within the heating
period), or below the reduced mode cutoff temperature
(outside the heating period).
The heating circuit pump switches off again as soon
as the current outdoor temperature rises above the
value of the cutoff temperature.
Heating circuit name
Individual naming of the heating circuit is possible.
6.1.3 Heating curve
The heating circuit flow temperature is controlled by
the heating circuit operating mode > 6.1.1 and by the
outdoor temperature. The heating curve represents the
relationship between these two temperatures. I.e. the
control unit uses the outdoor temperature to calculate
the temperature (=calculated nominal flow tem-
perature) with which the heating circuit is supplied.
In heating mode the heating curve for heating mode 4
(red) is used.
In reduced mode the heating curve for reduced mode 5
(= heating curve for heating mode minus reduction) is
used.
The heating curve must be adapted to suit each buil-
ding and its heating system.

6 Minimum heating circuit flow temperature[1]
7 Flow temperature at outside temperature -15°C
8 Flow temperature at outside temperature +15°C
!1) CAUTION - This temperature is system-spe-
cific and must be agreed with the heating engi-
neer. If there is a risk of the boiler overheating,
the hot water is discharged to the heating cir-
cuits at the Maximum heating circuit flow tem-
perature 1. Only to be set by qualified
personnel.
The desired heating circuit nominal flow temperature in
heating mode is set for an outside temperature of -
15°C 7and +15°C 8. Between these outside tem-
peratures, the nominal flow temperature is calculated
from the characteristics of the heating curve (inter-
polated).
Example for calculation of nominal flow tem-
perature (see the following illustration):
Flow temperature at outside temperature of -15°C =
45°C
Flow temperature at outside temperature of +15°C =
22°C
Current external temperature =-5°C
In the heating circuit operating mode Heating mode,
this applies:
> The computed flow nominal temperature (Pos.9) is
37.4°C
> The heating circuit is supplied with 37.4°C.
In the heating circuit operating mode Reduced mode,
this applies:
Reduction =10°C
> The computed flow nominal temperature (Pos.10) is
27.0°C
> The heating circuit is supplied with 27.0°C.

Adaptation of the 2-point heating curve (in hea-
ting mode)
iNote the currently set temperature before you
change the values.
A change in heating curve cannot be felt immediately.
Instead, this depends largely on the kind of heat dis-
tribution system (e.g. underfloor heating) and the buil-
ding standard (brick, lightweight construction etc.). It
is advisable to adapt the heating curve in small incre-
ments (+/- 2°C) with corresponding pauses (1 to 2
days). Depending on the current outside temperature,
different adjustments need to be made.

iFunction must be activated by qualified per-
sonnel.
Depending on the standard of building and insulation, it
is advisable to change over from the 2-point to a 3-
point heating curve. In contrast to the 2-point heating
curve, it is possible to stipulate a third temperature 11,
i.e. the heating curve can include a sharp deflection or
bend.

7 DHW heating
DHW can be heated up in two ways:
–With a DHW tank > 21
the energy source of the DHW tank is the heating
boiler or a buffer tank[1])
–With a fresh water module > 22
(The energy source of the fresh water module is a
buffer tank[1])
i[1]DHW area in the buffer tank
Warm water rises and collects in the upper-
most area of the buffer tank (= thermal stra-
tification). The DHW tank or the fresh water
module draws the required energy for DHW
heating from this uppermost area. Therefore,
this (held at an adjustable temperature level)
area in the buffer tank is also referred to as the
DHW area.

Drinking water area priority
Automatic:The DHW area is supplied with power at
the same time as the heating circuits.
On: Supply to the DHW area takes priority over sup-
plying the heating circuits. The heating circuit pumps
switch off as soon as a charging request is received
from the DHW area.
Reduced: The DHW area is supplied with power at the
same time as the heating circuits, but the heating cir-
cuits are supplied at the reduced temperature.
