Hints on energy saving

• Use the normal heating mode, thus the heating system will use the
least energy. Set the desired room temperature according to your
personal comfort needs.
• Open the thermostatic vents fully in all rooms. Increase the
temperature setting on the control only when the desired room
temperature has not been reached for some time. Close the
thermostatic valve in a specific room, only if that room is warmer then
the others.
• If there is a room controller installed, this can be used to set the
optimal room temperature. Avoid influence of external heating (i.e
sunlight or wood stove). Otherwise unwanted fluctuations in the
room temperature may occur.
• Avoid placing big objects e.g. a sofa in front of the radiators
(minimum 50 cm distance). This will block the circulation of the
heated air in the room.
• Do not set a too low temperature for cooling. Cooling will also
consume energy.
Vent the room correctly
Open the windows fully for a short period instead of leaving them ajar.
Leaving the windows ajar will let the heated air out of the room constantly
without increasing the air quality. Close the thermostatic valves or lower
the heating setting on the room controller while the room is vented.

WARNING
Material damage from frost!
The heating or auxiliary heater may be irreparably damaged by frost.
▶ Do not start the indoor unit if there is a possibility of the heating or
auxiliary heater being frozen.

Control unit

The user interface HPC 410 controls max. 4 heating circuits individually
in one of the respective control modes:
• Outdoor-temp.-compensated
– the flow temperature is adjusted based on the outside
temperature according to an optimised heating curve.
• Outdoor-temp.-compensated with low end
– the flow temperature is adjusted based on the outside
temperature according to a simplified heating curve.
For both of the control modes a room controller may be installed in the
reference room to allow the influence of the measured and required
room temperature. The heating curve is then adjusted accordingly.
The user interface HPC 410 is installed in the appliance and cannot be
used as room controller. Ask your contractor for available room
controllers.
Rule of thumb for outdoor-temp-compensated control with influence of
room temperature: the thermostatic valves in the reference room (the
room in which the remote control is installed) must be fully open!

The cooling function is not available in Belgium or Denmark.
The cooling menu items mentioned in this manual may be hidden if the
installed system is not suitable for cooling.
The electric booster or additional heater are not available for normal
operation in Denmark. The heater is however allowed to run in fault
mode, for extra DHW and thermal disinfection.
Depending on the software version of the user interface, the texts shown

At electric power failure or periods with disconnected heat source, no
settings are lost. The control unit will restart when the power is restored.
It is possible that time and date may need to be reset. No other settings
are needed.
