1 About this document
1.1 Target group of the instructions
These instructions for Extension board 'Performance' (EWP L) 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 Extension board 'Performance' (EWP L) 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
These instructions for Extension board 'Performance' (EWP L) are kept by the operator of Extension board
'Performance' (EWP L) after use for future reference.
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
The power extension board is used to measure the power of heat generators.
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
Extension board 'Performance' (EWP L) from this documentation.
3.2 Conformity
We, the manufacturer, hereby declare that Extension board 'Performance' (EWP L)
complies with the basic directives concerning the placing on the market in the EU.
3.3 Functional description
The power expansion board measures the flowing energy.
Monitoring the sensors is essential for safe operation of the system. It is also helpful for servicing to obtain
precise data on the operating status.
The following sensors and flow rates are used for heat measurement: Flow and return sensors and volume
flow Huba Control. These sensors are used for every existing heat generator.
The EWP output can be used to determine the yields for two heat generators;
- auxiliary heater 1 and auxiliary heater 2 of the EWP base
- tiled stove (using EOS) and auxiliary heater 1 (EWP base).
When using the expansion board, the software version on the system must be Rel. 5.0 or higher.

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 9: 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.

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.
