1 About this document
1.1 Target group of the instructions
These instructions for Extension board 'Basic' (EWP Basis) 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 'Basic' (EWP Basis) 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 'Basic' (EWP Basis) are kept by the operator of Extension board 'Ba-
sic' (EWP Basis) after use for future reference.
IMPORTANT
READ CAREFULLY BEFORE USE
KEEP FOR FUTURE REFERENCE

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 Extension board 'Basic' (EWP Basis) can only be used in conjunction with other BRUNNER units. For
example, with BRUNNER log boilers (Scheitini, Scheitikus or Scheitikum), BRUNNER pellet boilers (Pelletini,
Pelletikum, Pelletikus) or the electronic stove control (EOS).
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 'Basic' (EWP Basis) from this documentation.
3.2 Conformity
We, the manufacturer, hereby declare that Extension board 'Basic' (EWP Basis) com-
plies with the basic directives concerning the placing on the market in the EU.
3.3 Functional description
The Basic expansion board is responsible for the heat management of the heating system.
It controls the heat generation according to the operator's requirements. The heat generators can be: log
boilers, pellet boilers, wood chip boilers, but also wood-burning stoves, connected to an EOS (electronic
stove control). All BRUNNER natural energy boilers and stoves can be operated with or without solar sys-
tems, oil or gas boilers. The heat consumers can include Radiators, convectors, wall heating, underfloor
heating.
The heating circuit is equipped with an outdoor temperature control. In heating mode, the flow temperature
for the controlled heating circuit is determined from the outside temperature and the set heating curve. The
base point and the design point can be entered separately for each heating circuit. The user can choose indi-
vidually from different heating systems for each heating circuit or make an individual setting.
When using the expansion board, the software version on the system must be Rel. 5.0 or higher.
3.4 Special adjustable functions
Disinfection of the hot water tank
The thermal disinfection of the hot water storage tank serves to prevent the formation of legionella. This dis-
infection takes place automatically at the time and temperature you set.
© 2023 Brunner GmbH Instructions for use EWP Basis (2.33) 9

Frost protection
The Extension board 'Basic' (EWP Basis) is equipped with heating circuit frost protection. This has priority
over all selected settings. As soon as the specified outside temperature (frost protection) is reached, the in-
active circulation pumps of the heating circuits are automatically switched on. If the circulation pumps are al-
ready active, this function is omitted.
Summer/winter changeover
If the outdoor temperature exceeds the summer switchover threshold, the heating circuit pumps are de-
activated. An individual summer/winter switchover value can be set for the heating circuit. There is also
the option of setting summer or winter permanently. If the outside temperature falls below the summer off
switchover threshold by more than 1°C, winter mode is started automatically.
Standard programs for the heating circuits
The 3 standard programs can be used separately for each individual heating circuit. Three time intervals
can be selected for each day of the week. You can easily enter the standard programs on the display, in the
home view, without a PIN code and also name them individually. The switching times of a standard program
can be changed or added to. Three further program levels are available for other individual program requests
(New 1, 2 or 3).
Dry screed
If a heating circuit is equipped with underfloor heating, a special drying program can be set. As soon as the
drying process is complete, the setting is automatically reset to “No”. The active drying program for the rele-
vant heating circuit is shown on the display. The necessary parameters are preset at the factory, but can be
changed.
Continuous operation
In this setting, the system automatically switches to day mode for an adjustable period of time (hours). The
continuous operation function starts immediately and is automatically deactivated after the preset time period
has elapsed. The day/night changeover takes place automatically.
Absence
With the absence program, the desired heating circuit or an existing external hot water cylinder can be oper-
ated in frost protection mode for an adjustable period of time (days) during absence. This means that the rel-
evant heating circuit is switched off, but frost protection is active as it has the highest priority. The absence
function starts immediately and is automatically deactivated after the preset period of time has elapsed. The
system switches to automatic heating mode. The absence program can be interrupted/cancelled or resumed.
An active vacation program is shown on the display. The vacation days or absence time are displayed and
counted down.
Calibration offsets
Carry out a calibration to guarantee a match between the measured values recorded and the measured val-
ues output by the sensors. If there is a temperature deviation of the sensor, a change in degree Celsius in-
crements is possible under Settings.
Corrosion protection
Corrosion protection of all pumps and mixers is very important to ensure a long service life for the entire
heating system.
10 Instructions for use EWP Basis (2.33) © 2023 Brunner GmbH

When corrosion protection is active, all pumps and mixers are monitored by the function modules for a short
time. During corrosion protection, the mixers and pumps are briefly activated and realigned on the first Mon-
day of each month at 1:01.
