▪ Which heat emitter types are used in each room and what is their
design leaving water temperature?
Once the space heating/cooling requirements are clear, we
recommend to follow the setup guidelines below.
NOTICE
If an external room thermostat is used, the external room
thermostat will control the room frost protection. However,
the room frost protection is only possible if [C.2] Space
heating/cooling=On.
INFORMATION
In case an external room thermostat is used and room frost
protection needs to be guaranteed in all conditions, then
you have to set Emergency [9.5] to Automatic.
NOTICE
An overpressure bypass valve can be integrated in the
system. Keep in mind that this valve might not be shown
on the illustrations.

▪ For more information about connecting the electrical wiring to the
unit, see "8.2Overview of electrical connections for external and
internal actuators"[435].
▪ The underfloor heating or radiators are directly connected to the
indoor unit.
▪ The room temperature is controlled by the dedicated Human

Configuration
Setting Value
Unit temperature control:
▪ #: [2.9]
▪ Code: [C-07]

operation is decided based on
the ambient temperature of the
dedicated Human Comfort
Interface.
Setting Value
Number of water temperature

0 (Single zone): Main
Benefits
▪ Highest comfort and efficiency. The smart room thermostat
functionality can decrease or increase the desired leaving water
temperature based on the actual room temperature (modulation).
This results in:
▪ Stable room temperature matching the desired temperature
(higher comfort)
▪ Less ON/OFF cycles (more quiet, higher comfort and higher
efficiency)
▪ Lowest possible leaving water temperature (higher efficiency)
▪ Easy. You can easily set the desired room temperature via the
user interface:
▪ For your daily needs, you can use preset values and schedules.
▪ To deviate from your daily needs, you can temporarily overrule
the preset values and schedules, or use the holiday mode.
