6 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.
Tips about DHW tank temperature
▪ Use a weekly schedule for your normal domestic hot water needs
(only in scheduled mode).
▪ Program to heat up the DHW tank to a preset value ( Comfort =
higher DHW tank temperature) during the night, because then
space heating demand is lower.
▪ If heating up the DHW tank once at night is not sufficient,
program to additionally heat up the DHW tank to a preset value
(
Eco
= lower DHW tank temperature) during the day.
▪ Make sure the desired DHW tank temperature is NOT too high.
Example: After installation, lower the DHW tank temperature daily
by 1°C and check if you still have enough hot water.
▪ Program to turn ON the domestic hot water pump only during
periods of the day when instant hot water is necessary. Example:
In the morning and evening.

▪ 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
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO
2
equivalent.
Formula to calculate the quantity in CO
2
equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
Please contact your installer for more information.
WARNING: MILDLY FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
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.
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.
