INFORMATION
Maximum and minimum setpoints
You cannot configure the curve with temperatures that are
higher or lower than the set maximum and minimum
setpoints for that zone. When the maximum or minimum
setpoint is reached, the curve flattens out.
To fine-tune the weather-dependent curve: slope-offset curve
The following table describes how to fine-tune the weather-
dependent curve of a zone:

Energy saving tips

Tips about room temperature
▪ Make sure the desired room temperature is NEVER too high (in
heating mode) or too low (in cooling mode), but ALWAYS
according to your actual needs. Each saved degree can save up
to 6% of heating/cooling costs.
▪ Do NOT increase/decrease the desired room temperature to
speed up space heating/cooling. The space will NOT heat up/cool
down faster.
▪ When your system layout contains slow heat emitters (example:
underfloor heating), avoid large fluctuation of the desired room
temperature and do NOT let the room temperature drop too low/
rise too high. It will take more time and energy to heat up/cool
down the room again.

▪ Use a weekly schedule for your normal space heating or cooling
needs. If necessary, you can easily deviate from the schedule:
▪ For shorter periods: You can overrule the scheduled room
temperature until the next scheduled action. Example: When
you have a party, or when you are leaving for a couple of hours.
▪ For longer periods: You can use the holiday mode.

Maintenance and service

7.1 Overview: Maintenance and
service
The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.
1 Go to [8.3]: Information > Dealer information.
As end user, you have to:
▪ Keep the area around the unit clean.
▪ Keep the user interface clean with a soft damp cloth. Do NOT use
any detergents.
▪ Regularly check if the water pressure is above 1 bar.
Refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R32
Global warming potential (GWP) value: 675
Periodical inspections for refrigerant leaks may be required
depending on the applicable legislation. Contact your installer for
more information.
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
WARNING
▪ The refrigerant inside the unit is mildly flammable, but
normally does NOT leak. If the refrigerant leaks in the
room and comes in contact with fire from a burner, a
heater, or a cooker, this may result in fire, or the
formation of a harmful gas.
▪ Turn OFF any combustible heating devices, ventilate
the room, and contact the dealer where you purchased
the unit.
▪ Do NOT use the unit until a service person confirms
that the part from which the refrigerant leaked has been
repaired.
WARNING
The appliance shall be stored so as to prevent mechanical
damage and in a well-ventilated room without continuously
operating ignition sources (example: open flames, an
operating gas appliance or an operating electric heater).
WARNING
▪ Do NOT pierce or burn refrigerant cycle parts.
▪ Do NOT use cleaning materials or means to accelerate
the defrosting process other than those recommended
by the manufacturer.
▪ Be aware that the refrigerant inside the system is
odourless.
