1 About this document
1.1 Target group of the instructions
These instructions for Extention board (EWP) Oil / Gas / Solar are intended for the operator of the system.
The PIN code for the operator is 9999.
1.2 Validity of the instructions
The documentation for the product Extention board (EWP) Oil / Gas / Solar is valid from November 2015.
Ulrich Brunner GmbH reserves the right to make technical changes insofar as they serve technical progress
or are required by safety regulations.
1.3 Storage of the documents

IMPORTANT
READ CAREFULLY BEFORE USE
KEEP FOR FUTURE REFERENCE
The operator is responsible for keeping these operating instructions and all other applicable documents.
1.4 Symbols used
A hazard is a potential source of injury or damage to health.
A risk is the combination of a probability and the severity of injury or damage to health that can occur in a hazardous
situation.
The danger zone is the area and radius in which the boiler with/without the heating system is located, in which the
safety or health of a person could be at risk.
A person at risk is a person who is wholly or partially located in a danger zone.
The operating personnel are the persons responsible for installing, operating, setting up, maintaining, cleaning, re-
pairing or transporting the system.
In this documentation, a distinction is made between:
Operating personnel as the operator of the system, i.e. the end customer who has been instructed by the specialist
personnel and does not need to have any additional qualifications.
Operating personnel as a specialist company are the qualified specialists who are authorized to carry out the speci-
fied specialist work.
The following symbols are used in this document:
DANGER
There is a high-risk hazard that will result in serious injury or death if this hazard is not avoided.
WARNING
There is a possible medium-risk hazard that can lead to serious injury or death if this hazard is not avoid-
ed.
CAUTION
There is a low-risk hazard that can lead to minor or moderate injury if this hazard is not avoided.

2.2 Warnings
Warnings in this document are emphasized by pictograms and signal words.
The pictogram and the signal word indicate the type, the source or causes of a certain action. The necessary
precautions or instructions to be followed are indicated.
The same applies to results or desired effect of an action.
These warnings refer to possible misuse of the system, which seems likely based on our experience.
Certain residual risks are also indicated.
The residual risks are inevitable:
- despite the safety measures considered in product design,
- despite the safety precautions,
- despite the complementary protective measures.
For certain points we have provided recommendations and instructions on how to use protective measures,
including personal protective equipment.
Special safety instructions and recommendations are applied for transport, handling and storage.
Instructions for safe set up and maintenance include separate protective measures too.
Structure of warnings
The warnings that precede each assembly step, are shown as follows:

3 Product description
3.1 Intended use
For all other types of application, please contact Ulrich Brunner GmbH.
Intended use also includes observing all information on personal and material hazards in these operating in-
structions. Also comply with all country-specific standards and safety regulations.
Read and observe all information and recommendations on installation, operation and maintenance for the
Extention board (EWP) Oil / Gas / Solar from this documentation.
3.2 Conformity
We, the manufacturer, hereby declare that Extention board (EWP) Oil / Gas / Solar
complies with the basic directives concerning the placing on the market in the EU.
3.3 Functional description
The Basic extension board is responsible for the heat management of the heating system.
Heat generators can be all natural gas boilers and stoves from BRUNNER and can be operated with an addi-
tional solar system, oil or gas boiler, etc. when an oil-gas-solar extension board is connected.
The heat consumers can be Radiators, convectors, wall heating, underfloor heating.
The mixer, which hydraulically connects the additional heating 3 directly to the heating circuits or the hot wa-
ter cylinder, is controlled via the EWP oil-gas-solar.
When using the expansion board, the software version on the system must be Rel. 5.0 or higher.

An important difference to conventional central heating systems is the direct charging of the hot water cylin-
der during operation of the solar thermal system. The relevant pipe is routed under the system cylinder di-
rectly to the hot water cylinder.
Once the hot water cylinder has been fully heated (temperature threshold in the upper area of the hot water
cylinder), the buffer is charged.

4.5.1 Auxiliary heating 3 of the EWP oil-gas-solar
An additional heating system, either an oil boiler or gas boiler, can be connected to the EWP oil-gas-solar ex-
tension board without measuring the heat quantities. The mixer, which hydraulically switches on the auxiliary
heating, is controlled via the EWP oil-gas-solar. Auxiliary heaters 1 and 2 of the EWP Basis are offered when
an EWP oil-gas-solar is connected on side 2 and side 3.

5 Information and error messages
Based on the highest industry standards, all BRUNNER expansion boards have a detailed safety concept.
The controller not only regulates and monitors the current operating status, but also independently and
continuously checks the function of all connected sensors, motors and mixers.
The safety concept
•Continuous electronic monitoring of all connected sensors, such as boiler and flue gas sensors, as well
as monitoring of connected electrical components;
•Automatic and permanent archiving of sensor values and error messages.
•Visual display of error messages.
Display of an information or error message
If a message or error message occurs, a corresponding mes-
sage window appears on each existing operating display within
the BRUNNER network environment, as well as a short signal
tone.
To confirm the message, proceed as follows:
•Tap O.K. to confirm
→ The message is deleted from the operating display and, in
the event of an error message, permanently saved in the histo-
ry.
Illustration 5: Note/error message
Display error messages
If there are active error messages, the Info button is highlighted in orange.
To display error messages, proceed as follows:
•tap Info in the top menu bar of the Home view
→ Error messages are displayed.
Error messages can only be acknowledged in the top menu bar of the Home view in the Info submenu.
5.1 Acknowledging error messages
To acknowledge an error message, proceed as follows:
1. tap the Info button;
2. in the lower half of the display, press Reset
→ The error message has been acknowledged.
If the error is still present, the error message appears again.
Error messages can only be acknowledged in the top menu bar of the Home view in the Info submenu.

The following error codes can appear on the oil-gas-solar expansion board and are shown on the display:
Error text Error text Description Note to the operator
Fehler EWP Sensor De-
fekt S-E08
= Error EWP
Sensor defect S-E08
The temperature sensor in the collector field of the collector
circuit is defective or not connected. Contact a specialist company
Fehler EWP Sensor De-
fekt S-E10
= Error EWP
Sensor defect S-E10

Fehler EWP Sensor De-
fekt S-E11
= Error EWP
Sensor defective S-E11
The temperature sensor in the bottom of the hot water cylin-
der is defective or not connected. Contact a specialist company
5.3 Troubleshooting
Switch emergency program
In the event of faults during the heating period, the query appears on the display:
Switch emergency program (= Notprogramm schalten) with the selection options: Yes/No (= Ja/Nein)
In this case, contact a specialist immediately.
The radiators should also heat up in winter if sensors are faulty. However, there is a protective function for
the underfloor heating.
The system display is in the heating circuit emergency program (= Notprogramm).
The reset for the error can be ended here or under Info.
