1.2
Recommendations
The system may only be operated for the purpose of the intended use as described in the present document.
Combined heat and power units (CHP) are appliances that produce electricity and heat at the same time
according to the principle of cogeneration. The Dachs works according to this principle, but is planned for the
local operation and usage of the produced energy inside buildings.
Another or usage going beyond the norm is regarded as unintended use. SenerTec GmbH shall not assume any
liability for any damage resulting from this unintended use. The operator bears the entire risk.
Danger:
Operate the system for the purpose of its intended use only.
Any unintended use may lead to personal injury or damage to the machine.
The following situations are regarded as improper operation:
●● The operation with fuels other than those described and admitted.
●● Operation with machine settings changed by the operator.
●● Operation with supply connections changed by the operator.
●● Operation outside of building.
●● Operation outside the permitted ambient conditions is not allowed.

4 Description of the product
4.1
General description
The Dachs is a micro CHP system to cover heating, electricity and domestic hot water demand. The
output, reliability and funtionality is suitable for small buildings with high heat demand as well as
for commercial, office, public and multi apartment buildings.
The Dachs can operate as a single unit as well as in a multi module system with up to 10 modules.
Each Dachs unit can provide 5.5 kW electrical and up to 14.8 kW thermal (with condensing unit).
4.2
Operating principle
The Dachs is a typcial CHP product. A special 4-stroke single cylinder Sachs engine is connected
to a water cooled asynchronous generator. The generated mechanical energy is directly
transformed to electricity. At the same time the produced heat is captured and used, for example,
in a heating or DHW system, and not dumped as in conventional power plants.
By the combination of heat and power the energy (e.g. fuel oil, natural gas) is used more efficient
ly in conventional seperate generation. The transformation of the primary energy is realised within
a cycle means that 25 to 30 % of the input energy is transformed into mechanical movement.
The other 70 to 75 % is transformed into heat and is captured via heat exchanger and used for
heating and DHW. The total efficiency is more than 90 %, the efficient use of the primary energy
is optimised comparison with seperate generation of heat and electricity and therefore 30 % of
primary energy can be saved.
During the operation of one Dachs unit 5.5 kW electrical and 14.8 kW thermal can be produced
simultaneously.
The unit is controlled by the MSR2 controller. The MSR2 controller is designed especially to meet
the requirements of the Dachs CHP unit:
●● Start and operation of the Dachs.
●● Feed-in of the electrical energy to the building´s grid or the public grid.
●● Supply of the thermal energy for the heating or for the domestic hot water system.
●● Supervision of the operating parameters of the Dachs.
●● Monitoring of the feed-in.
●● Monitoring of the operating safety in case of grid or phase failure (safety chain).
●● Control of the combustion supply.
14/4798.232.106
Description of the product | 29
Dachs with MSR2
It is possible to combine 10 units to a multi module system as a cascade. Any controller can be the
master to control the other 9 slave units of the multi module system. The following features are
available by the master controller:
●● Synchronisation of the operating hours of all modules. All units reach the maintenance
interval at the same time.
●● Optimised re-start of modules which are still at operating temperature.
●● Activation of an additional heat appliance (dual mode) according to heat demand.
●● All controllers can be master or slave controllers.
●● Activation or deactivation from 1 to 10 units with additional release of another heat
appliance.
●● Independet operation of the slave units in case of fault or deactivation of the master unit.
●● Only one flow (VF), return (RF) and outside (AF) temperature sensor necessary.
●● Data transfer of operation status between slave units ot master unit via BUS cable. Data
transfer of all units by modem installation only at master controller.
●● Display of master function at the controller and via the service program.

The nominal electrical power of the Dachs is to be reduced with the
increasing installation height, due to the low air pressure. The MSR2
control software enables a configuration of the installation height of
0 - 3500 m in steps of 100 m. Starting at a height of 800 m above sea level,
the output will be reduced. At 800 m it starts in steps of 100 m the output
will be reduced by 83 W.
Note:
See Operating and adjusting instructions
MSR2 (art. no.: 4798.234.xxx),
menu 1/8/5 Height above sea level.
5.2.2 Remote monitoring
For the Dachs, a remote monitoring system is available. The current
operating status or upcoming maintenance work on your Dachs may be
transmitted to the SenerTec server via Ethernet module. This enables a
short response time in the case of errors. For using the remote monitoring
function, the following framework conditions are to be fulfilled:
In the event of an unfavourable reception at the installation location,
an external antenna may be installed. The external antenna and the
extension cables are available in electronics stores. Please ensure that

pH-value of the filling and recharge water:
For the Dachs products, SenerTec allows for a pH-value between 7.0 and 8.5. The SenerTec recommendation is limited to
a range between 8.0 - 8.5, however.
For a comprehensive survey of the heating system, especially with larger heating systems or multi-boiler systems, reference
values are to be adhered to, i.e. pH 8.2 - 8.5.
!
Attention:
The pH-value may not exceed the admissible maximum value of 8.5.
If, in special cases, inhibitors and/or additives are required in mixed applications (e.g. hardness stabilisers, antifreeze, sealants
etc.), it is to be ensured that the agents are compatible with each other and that the pH-value is not altered. Please observe
the instructions provided by the manufacturer of the given additive.
Currently, the following inhibitors have been approved for the Dachs:
●● GENO-safe A Full heating protection by the company Grünbeck.
●● Protector F1 (full heating protection) by the company Fernox.
●● Sentinel X100 by the company Sentinel Performance Solutions.
!
Attention:
If you use agents which have not been approved, the warranty becomes null and void.
Please note:
●● Heating water may only be used for the purpose of heating in a closed circuit.
●● Heating systems with underfloor heating must contain a mud trap (oxygen diffusion).
●● Underfloor heating systems made of plastic tubes which are not oxygen tight according to DIN 4726 must contain
a heat exchanger as system separator.
●● The heating water (filling water of the buffer vessel) must be softened and desalinated if required.
●● The operating pressure must amount to a minimum of 1 bar.
14/4798.232.106
Dachs with MSR2
The following operational protective measures are recommended:
●● Keep the volume of recharging water low by installing isolating valves in case repair work needs to be carried out
as well as to allow for the regular inspection of the expansion vessel.
●● The addition of chemicals in order to stabilise the hardness should be avoided since calcium carbonate may fall
out as mud.
●● The safest methods for avoiding the formation of limescale are softening and desalination in the cation exchange
procedure, the ion exchange procedure or the reverse osmosis.
5.2.4 Heating system and return temperatures
Heating system:
●● The installation shall comply with the Dachs installation instructions and the local regulations.
●● The connection to the heating water system must be according to local regulations (Germany: DIN 4751/T2) with
an absolute temperature of the boiler less than 100 °C.
Maximum and minimum return temperature (Dachs G/F: 6 in Fig. 3; Dachs HR: 4 in Fig. 4):
●● Permitted return temperatures during normal operation between are 20 °C and 70 °C. Temperatures below 20 °C
may not be used during continuous operation.
●● Temperatures below + 10 °C are not permitted.
5.2.5 Gas installation
!
Attention:
The gas installation is to be carried out in accordance with the technical rules of the local gas supply companies
and the applicable local regulations for gas installation and may only be carried out by specialist staff with the
respective authorisation to carry out work involving gas.
i
Notice:
The gas pressure of the supply line is to be checked as early as possible in the planning phase.
If the pressure of the gas duct exceeds a value of 54 mbar, a pressure reducer is to be installed
in order to reduce the gas pressure at rest to a maximum value of 50 mbar.
The pipe diameter of the gas duct to be used depends on the length of the gas supply line.

5.2.10 Multi module system
Precondition for multi module systems:
To create a multi module system with MSR2 controller, a minimum of 2 Dachs units are necessary. An extension of the system
is possible up to 10 Dachs units.
The control of the modules is done by a master controller. All other Dachs units are connected as module M2 to M10 and
receive all information from the master controller. The contoller of the each Dachs transfers all its operation and status data
to the master controller.
To establish a multi module system with the Dachs units it is necessary to create a serial connection between the units. There
are multi module cable in 5 and 15 meters available. On each end of the cable are grommets to fit into the controller.
For each Dachs unit a connection cable is necessary. The first and the last module must be installed with a terminating
resistor on the controller board. The resistor is installed by default on each MSR2 controller.
All external sensors (return sensor [RF], flow sensor [VF], outside sensor [AF] and sensor 1 [F1] are connected to the Master
controller L1. No sensor has to be installed at the other slave units.
If a thermostatic pump is installed, please note that only max. 3 units can be connected to one pump. Depending on the
number of the units, the thermostatic pump has to be connected according following description:
●● 2 - 3 Dachs units: Connection of thermostatic pump at master controller L1.
●● 4 - 6 Dachs units:
L1, M2 and M3: Thermostatic pump connected to L1.
M4, M5 and M6: 2nd thermostatic pump connected to M4.
●● 7 - 9 Dachs units:
M7, M8 and M9: 3rd thermostatic pump connected to M7.
●● 10 Dachs units:
M7, M8 and M9: 3rd thermostatic pump connected to M7.
M10: 4th thermostatic pump is connected to M10.
Note:
The electrical connection of the thermostatic pump is shown in the hydraulic booklet MSR2

The Dachs can be connected in different ways. In general the inlet water
should be supplied from the return flow of the heating circuit. The outlet
of the Dachs can be connected either into the flow of the heating system
or into the return of the heating system (then a distance of at least 30 cm
must be between inlet and outlet connection).

Refrigeration connections
Notice:
The connection of a refirgeration circuit is only necessary to dump excessive heat, that can not
be used inside the building.
The connection of a refrigeration circuit is a mandatrory requriement for an off-grid system. The
off-grid system is not connected to the public grid. The described Dachs units in this manual are
not suitable for an off-grid system.
In normal operation it is necessary to ensure that the produced heat is used in the building. If not
the Dachs does not meet the requirements of a high efficient CHP unit.
Please consider that the heat of the Dachs unit is always used in the building, if not, in some
countries it might be not allowed to connect the unit to the grid.

Notice:
Please check the local regulations for the installation of an assembly of fuel pipes and storage tanks. The
following possible connections are examples and are permitted in some European countries.
Checking the fuel supply:
The oil supply is to be carried out in accordance with local regulations. The outer diameter of the feed pipe at the oil filter is
8 mm. During operation, a max. intake pressure of 0.2 bar is allowed. The end of the suction intake pipe in the tank should
have a minimum distance of approx. 10 cm from the tank floor. Tank geometry permitting, the installation of a floating intake
is preferable.
If a booster pump is used, the max. supply pressure ahead of the filter must not exceed 0.2 bar. If higher oil pressures are
expected, a pressure reducer must be used in the supply flow line with a set output pressure of 0.1 or 0.2 bar.

Checking the fuel pipes are leakage proof:
The pressure check of the oil supply must not be carried out on the pressure connection of the oil vent, since the non-return
valve built into the appliance prevents the pressure being transmitted to the intake pipe.
The oil vent with filter is therefore not to be included in the pressure check.
Installing the fuel vent:

Notice:
Install the oil vent in such a way that when carrying out
maintenance work the filter insert can be replaced easily,
or a container can be placed underneath it.

The accessories include two oil connection hoses, the oil vent unit with
filter, and a mounting bracket.
►► Screw the mounting bracket to the wall or a suitable location.
►► Mount the oil vent to the mounting bracket using the
preassembled screws.
●● The ambient temperature must not exceed 60 ° C. The float
housing must be vertically upwards.

Attention:
Ensure that the sealing areas are clean to guarantee total
tightness. During commissioning, check the tightness of the
connections.
Fig. 80: Connection of fuel supply line to filter
Venting the fuel pipe (if start was unsuccessful):
To successfully run the system, vent the fuel supply. With longer suction pipes it is recommended to aspirate the fuel by
means of a hand pump or with a suction canister for lubricating oil at the flow supply-vent (Figure 8b-5). With short suction
pipes it is sufficient, if the existing fuel pump in the Dachs is hand-operated (see operating- and adjusting instructions
MSR2). The activation can be effected after the first test start for max. 10 min via Service-Menu (11/8/7/1 or 11/8/7/2) at the
controller.
This function helps to fill the heating oil filter. After confirming the menu with yes, and after a short delay, the tick is shown.
Now the fuel valves and the internal heating oil pump are activated. The activation will end after leaving the menu or changing
to automatic mode or independently after 2 minutes. An external heating oil pump will not be activated automatically. If
necessary it can be done in menu 11/8/7/2.
!
Attention:
The manual activation can be repeated not more than 3 times.
Mind that the fuel pump does not run dry for any length of time to avoid damage.
But if the fuel supply is carried out via booster pump no special venting is necessary.
Options for fuel supply:
The following options are possible:
1. Running a separate intake pipe for the Dachs up to the oil tank and a separate connection at the tank. This layout
prevents any interaction.
2. Changing the boiler to a single-leg connection and using the common oil intake pipe for boiler and Dachs.
Therefore, the reduced flow volume during operation (only consumed oil volume) is to be taken into account.
3. Running a separate intake pipe for the Dachs up to the oil tank. Dachs connection with separate shutoff valve
behind the shut-off valve for the boiler. This layout is possible if no separate tank connection is possible for the
Dachs.
4. Connection to the boiler intake pipe in the installation room. The intake pipe must be suitable for the sole
operation of the Dachs (flow approx. 2 l/h). In particular, the non-return valve in the boiler return flow pipe must
close absolutely tightly to ensure that there is no air intake. This solution should only be used if implementing the
other solutions (1st to 3rd) requires a disproportionate effort.
i
Notice:
SenerTec recommends the 1st option with separate intake pipe to the oil tank.
Tank geometry permitting, the installation of a floating intake pipe is preferable.

Notice:
The requirements for the Dachs oil supply are basically the same as the oil supply of a heating boiler.
In general, the permitted oil pressures at the Dachs inlet (pressure max. 0.2 bar, underpressure min. 0.2 bar)
must be maintained.

6.9.2 Power factor correction of the Dachs
Every MSR2 controller is equipped with a capacitor to comply with the country specific requirements of a lagging operation.
The capacitor is installed behind the power board and protected by the fuses F8, F9 and F10.
i
Notice:
In the lagging operation the generator takes inductive reactive power from the public grid. In this way the
voltage rise is reduced when the generator feeds into the grid. The positive effect is a stabilisation of the
voltage network of the public grid.

Fitting the internal cable harness:
►► Feed the cable harness located inside the Dachs through the
access hole in the controller housing.
grommet
Tip ►► Feed all plugs from the cable harnes individually through the
insulation / grommet.
!
Attention:
Ensure that the edge protection of the access hole is still
correctly seated after feeding the cable harness through. No
cables should lie directly on the sheet metal edge, as the wire
insulation could get damaged during operation.

In accordance with local regulations (VDE 0116 or EN 57116) an emergency stop switch may be required to be installed
outside the installation room. Emergency shutdown is done either directly via a 4-pole or a 1-pole emergency stop switch
with double-throw contact, which is integrated in the safety chain of the Dachs. By using the safety chain, the emergency
shutdown can also be carried out via the contactor of an existing emergency shutdown circuit.
If the Dachs is installed in its own room, a new emergency stop switch must be fitted.

characteristics, definitions.
!
Attention:
The connection according to DIN VDE 0100 551 is not possible to a final circuit. The installation of the
connection must be realised fix (without plug) e.g. in a sub distribution and over a isolator device with min.
3 mm contact distance (e.g. fuses, circuit breaker). Other electrical devices are not allowed to be connected in
the supply.
Note:
Also see Instructions for the installation and operation of the immersion
heater for the Dachs SE (only MSR2 V2.0) (art. no.: 4798.212.xxx).
Note:
Detailed information about the connection are available at the connection diagram (art. no.: 4798.415.xxx)
in the MSR2 controller door as well in following chapter Connection MSR2 controller.
Protection devices and cable length:
The mains supply connection of the Dachs should be ensured with
3 × 20 Amp, type C or K circuit breakers in the supply line 1.
To reduce voltage losses and shut downs because of over voltage,
ensure a correct design of the supply line with minimum voltage drop.
Furthermore the supply line must be designed for a circuit breaker of
20 Amps, cable length and type of cable conduit. The cable size must be
at least 5 × 2.5 mm².

7.4.2 Adjust the gas flow control (Dachs G/F)
The servo motor of the gas flow control is in its operating position if the
unit is at operating temperature.
►► Check if the gas flow control is in the middle of the
possible range. Future variations in the gas quality must be
compensated.
At the drive shaft of the servo motor 1 you can see the scale wtih the set
point mark 2 and the set point is indicated by the pointer of the housing
3.
►► Check if position is at set point.
In the case that the pointer is not on the set point mark, the main jet
of the gas mixer must be exchanged in accordance with the following
instructions.
1
Adjustment of gas mixer:
Adjust the gas mixer only if unit is at operating temperature.
The default setting of the gas track is for natural gas type H.
►► In the case that the pointer is right of the set point mark, install
a smaller main nozzle (e.g. 2.7 mm with natural gas type H).
►► In the case that the pointer is left of the set point mark, install a
bigger main nozzle (e.g. 2.9 mm with natural gas type H).
i
Notice:
The step range of the main nozzle is 0.1 mm.
The change of one step changes the angle about 5-8°.
Please always have some main nozzles in your toolbox.
If necessary you can order them from SenerTec.

Attention:
With multi-module systems, the master controller should not be deactivated when it is planned to
continue to operate the other Dachs modules.
Frost protection
For systems in which temperatures of less than +5 °C might occur, the frost protection of the complete system is to be
guaranteed at all times. This can be done by implementing suitable installation measures, such as filling glycol into the
heating system or by means of appropriate heating.
!
Attention:
The subject of frost protection is to be handled in a detailed manner for systems which
are not operated throughout the whole year. The required measures should already be
clarified between operator and installer when planning the system.

10.2 Maintenance messages
There are three different ways with which the Dachs notifies the operator about the requirement of maintenance:
●● Red maintenance LED on the membrane keypad of the MSR2 controller.
●● Relay contact Maintenance in the MSR2 controller for external display.
●● Message sent via the remote control to the SenerTec server.
Precondition: GSM or Ethernet modem installed.
Notice:
On the display, in the Operating data menu, the maintenance interval can be read:
1 Operating data
1/08 Dachs data
i
1/08/07 Service interval
In the Service menu, the operating hours until the next maintenance is due to be carried out as well as the date of the last service was carried out are indicated:
11 Service
11/01 Service due in xxxx h
11/02 Last Service dd.mm.yy
142 | Maintenance
14/4798.232.106
Dachs with MSR2
Red service LED:
●● The LED flashes if there are less than 300 operating hours and/or less than 30 days (twoyear period) left until the next maintenance of the Dachs is due to be carried out.
●● The LED is illuminated continuously when the maintenance is overdue.
!
Attention:
The Dachs will deactivate with the service code 177 Service required.
Service relay contact:
●● The relay contact is closed if there are less than 300 operating hours and/or less than 30 days
(two-year period) left until the next maintenance of the Dachs is due to be carried out.
i
Notice:
With multi-module systems, the relay is activated at the master controller if one of the modules is less than 300
operating hours and/or less than 30 days away from the next maintenance due to be carried out.
At the master controller, the Service message can thus be centrally accessed for the multi-module system.
Message via remote monitoring:
●● The message is sent when the next maintenance of the Dachs is due in less than 30 days.
●● The message is sent each time the next maintenance of the Dachs is due in less than 300,
200 and 100 operating hours.
i
Notice:
With multi-module systems, the messages (master controller and module controller) are centrally
transmitted by the master controller to the SenerTec server. The server forwards the messages to the stored
recipients via email, SMS or fax.
10.3 Standard inspection and maintenance operations
The Dachs and the dedicated SenerTec components have to be maintained regularly by a specialist engineer authorised specifically for this purpose in accordance with the maintenance protocol and the recommended maintenance
measures as specified in the Service Booklet for Dachs G/F, art. no.: 4798.167.xxx, and Servicing instructions for the Dachs,
art. no.: 4798.255.xxx.
Such maintenance is to be carried out in intervals of a maximum of 3500 operating hours but at least every two years.
10.4 Specific maintenance operations

11 Troubleshooting
11.1 Error codes
The MSR2 controller of the Dachs differentiates between two types of error codes, i.e. between service codes and warning
codes. Service codes lead to a deactivation of the Dachs, while the Dachs may continue to run in the event of warning codes.
Depending on the service code, there is a defined number of automatic fault clearances. If all automatic fault clearances have
been unsuccessful, a manual fault clearance is required after the deletion of the errors.
There are three ways for error codes to appear at the Dachs:
●● Red service code LED on the membrane keypad of the MSR2 controller.
●● Relay contact Fault in the MSR2 controller for external display.
●● Message sent via the remote control to the SenerTec server. Precondition: GSM or Ethernet module installed.
Red service code LED:
●● The LED flashes when a warning code is present.
●● The LED is permanently illuminated if a service code is present.
i
Notice:
Manual fault clearance required.
Relay contact fault:
●● The relay contact is closed if a service code is present and a manual fault clearance is required.
i
Notice:
With multi-module systems, the relay at the master controller is activated even if a service code is present
at one of the other modules.
At the master controller, the error code can thus be centrally accessed for the multi-module system.
Message via remote monitoring:
●● The message is realised if a warning code is present.
●● The message is sent if a service code is present which is to be cleared manually.
i
Notice:
With multi-module systems, the messages are centrally transmitted by the master controller to the
SenerTec server. The server forwards the messages to the stored recipients via email, SMS or fax.
Note:
An overview of the service and warning codes can be found in:
144 | Troubleshooting

11.2 Error memory
In menu 10/3 Service code on the display, the last service and maintenance codes can be obtained.
10 Service code
10/1 Data of last S.Code
10/2 Warnings
10/3 Service codes
Furthermore, under 10/2/10 Reset warning codes current warning codes can be reset. For this purpose, the authorisation level Operator advanced level is required.
11.3 Fault finding
Common service codes are listed in a table in the document Operating and adjusting instructions MSR2
(art. no.: 4798.234.xxx).

12.2 Recommissioning procedure
i
Notice:
If the Dachs is out of operation for a longer time probably the internal water pump is blocked.
Please check before commissioning mobility of the pump.
After some time out of operation it is possible that at the recommissioning that dried oil deposit blocks the
outlet valve. In this case the engine probably can not start (service code 189). You can confirm this situation by
turning the fly wheel easily (no compression).
Note:
To remove the deposits act according to SenerTec training or contact SenerTec helpline.
1. Open valves for heating water in- and outlet.
