General safety instructions

These instructions are intended for the user of the heating
system
▶ Read the instructions (for heat source, modules etc.)
before use and keep them handy.
▶ Pay attention to the safety and warning instructions.
Intended use
▶ The product should only be used to control heating systems
in one-family houses.
All other use is not suitable. We cannot accept liability for
damages resulting from unauthorised use.
Inspection and maintenance
Regular inspection and maintenance are prerequisites for safe
and environmentally compatible operation of the heating
system.
▶ Have work carried out only by an approved contractor.
▶ If any faults are discovered, have them remedied
immediately.
Damage caused by frost
If the system is not in operation it can freeze:
▶ Follow the instructions to ensure protection from freezing.
▶ Always keep the system switched on for additional
functions, such as heating hot water or protection from
blocking.
▶ Rectify operating faults immediately.
Risk of scalding at the hot water draw-off points
▶ If hot water temperatures above 60 °C are set or if thermal
disinfection is activated, a mixer must be installed. If in
doubt, ask your contractor.

CLIMATE CONTROL SYSTEMS

The HPC 400 user interface makes it easy to operate your heat
pump.
Turn the selector to set the required room temperature in your
home. The thermostatic valves at the radiators or the room
thermostats for the underfloor heating system also control the
room temperature. If a room temperature-dependent
controller is present in the reference room, the thermostatic
valves in this room must be replaced by throttle valves.
The optimised way in which they work allows the system to be
operated in an energy-efficient manner. This method of
controlling the heating or cooling system optimises comfort
whilst minimising energy consumption.
DHW heating can be adjusted conveniently and controlled
efficiently.
2.1
The functional scope and thus the menu structure of the user
interface are determined by the structure of the system:
• Settings for a variety of heating/cooling circuits are only
available if two or more heating/cooling circuits are
installed.
• Information about solar systems is only displayed if a solar
system is installed.
• Certain menu items are specific to certain countries and
are only displayed if the country in which the heat pump is
installed has been set accordingly on the user interface.
Your attention is drawn to the importance of the system
structure in the relevant places. The setting ranges and basic
settings are determined by the local system conditions and
may deviate from the information provided in these
instructions.
Consult your contractor if you have further questions.
2.2
The user interface can control up to a maximum of four heating/
cooling circuits. For each heating circuit, either weather-
compensated control or weather-compensated control with
room temperature influence can be set on the user interface.
The main control modes for the heating system are as follows:
• Weather-compensated:
– The room temperature is controlled based on the
– The user interface sets the flow temperature in
• Weather-compensated with influence of room
temperature:
