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:

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 heating circuit extension board can only be used with the BRUNNER heating center BHZ or EWP Basis.
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 'Heating circuits' (EWP HK) from this documentation.
3.2 Conformity
We, the manufacturer, hereby declare that Extension board 'Heating circuits' (EWP
HK) complies with the basic directives concerning the placing on the market in the
EU.
3.3 Functional description
The heating circuit extension board is responsible for the heat management of the additionally connected
heating circuits.
The heat consumers can be radiators, convectors, wall heating, underfloor heating or swimming pool heat-
ing.
The heating circuit is equipped with an outdoor temperature-controlled control system. 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 individually from different heating systems for each heating circuit or make an individual set-
ting.
The EWP heating circuit is the control in the event that additional heating circuits are installed. So if there are
already 2 (usually existing) heating circuits, the extension board controls the 3rd or 4th heating circuit; how-
ever, this is also possible for a 5th or 6th etc. heating circuit. heating circuit.
There is the option of heating operation with outside temperature control and the option of heat dissipation.
When using the expansion board, the software version on the system must be Rel. 5.0 or higher.

3.4 Special adjustable functions
Frost protection
The Extension board 'Heating circuits' (EWP HK) 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 inactive circulation pumps of the heating circuits are automatically switched on. If the circulation pumps
are already 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.
