Important information
Additional symbols
1.2 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.
2 Product information
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 Range of functions
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 Function as controller
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
outside temperature
– The user interface sets the flow temperature in
accordance with a simplified or optimised heating
curve.
•Weather-compensated with influence of room
temperature:
This symbol indicates important information
where there is no risk to people or property.

Rule of thumb for weather-compensated
control with influence of room temperature:
the throttle valves in the reference room (the
room in which a remote control is installed)
must be fully open!
The HMC300 user interface is installed in the
appliance and cannot be used as remote
control. Ask your contractor for available
remote controls.

4 Getting started
An overview of the structure of the main menu and the position
of the individual menu items can be found on page 13.
Each of the following descriptions takes the standard display as
its starting point (page 2, Fig. 6 at left).
4.1 Selecting a heating circuit for the standard
display
The standard display only ever shows data for a single heating

5.2 Adapting settings for heating system
automatic mode
Menu: Heating/Cooling
Optimised operation (without a time program) is active for
each heating circuit by default. If required, the user can change
the setting and select the time-dependent automatic mode. A
constant room temperature value can be specified for cooling
mode.
Heating circuit 1 ... 4
If more than one heating circuit has been installed and
configured, the settings for heating circuits 1 ... 4 are changed
in the same way as for systems with one heating circuit.
However, changes are valid only for the selected heating
circuit. Assigning unique names to heating circuits makes it
much easier to make the right selection.
5.2.1 Heating temperature settings
The temperatures for the various operating modes can be set in
this menu. Depending on whether the user interface is working
in automatic mode or in optimised operation, the temperatures
have an effect on how the system is controlled.
Menu: Temperature settings
5.2.2 Adapting the Time program for heating system
automatic mode
The time program is only active for the heating system if
automatic mode is active (Chapter 4.2, page 8).
To set the same switching times for multiple days of the week:
▶ Set switching times for a group of days, e.g.
Mon-Sun or Mon-Fri.
▶ Adjust the time program for the specific days of the week
for which different settings are required under Monday ...
Sunday (detailed description Tab. 13, page 16).
Menu: Time program
The time program ensures automatic changeover between
operating modes at defined switching times. The user interface
has two time programs for each heating circuit. Two switching
times per day can be programmed, each with an operating
mode. The default settings for the time programs provide lower
heating overnight. Optimized mode provides the most
economic heating for both day and night.
If the settings, temperatures or switching times of the time
program do not meet your needs, you can adapt the time
program. If you do not require heating overnight, speak to your
contractor. He has access to additional settings for configuring
setback mode.
Menu item description
Heating If automatic mode is active, the room
temperature is maintained at the value
set here for the specified time slots with
the Heating operating mode.
Setback If automatic mode is active and a
temperature has been set here, the room
temperature is maintained at the value
set here for the specified time slots with
the Setback operating mode. If heating is
