3.4.2 Scheduled mode
In scheduled mode the DHWtank produces hot water corresponding
to a schedule. The best time to allow the tank to produce hot water is
at night, because the space heating demand is lower.

3.4.3 Scheduled + reheat mode
In scheduled + reheat mode, the domestic hot water control is the
same as in scheduled mode. However, when the DHW tank
temperature drops below a preset value (=reheat tank temperature –
hysteresis value; example: 35°C), the DHW tank heats up until it
reaches the reheat set point (example: 45°C). This ensures that a
minimum amount of hot water is available at all times.

4 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 the desired room temperature to speed up
space heating. The space will NOT heat up faster.
▪ When your system layout contains slow heat emitters (example:
under floor heating), avoid large fluctuation of the desired room
temperature and do NOT let the room temperature drop too low. It
will take more time and energy to heat up 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. 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. Example:
When you stay at home during your holiday, or when you go
away during your holiday.
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.
5 Maintenance and service

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
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
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

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.

6 Troubleshooting
6.1 To display the help text in case of
a malfunction
In case of a malfunction, the following will appear on the home
screen depending on the severity:
▪ : Error
▪ : Malfunction
You can get a short and a long description of the malfunction as
follows:
1Press the left dial to open the main menu and go to
Malfunctioning.
Result: A short description of the error and the error
code is displayed on the screen.
2Press in the error screen.
Result: A long description of the error is displayed
on the screen.
6.2 Symptom: You are feeling too cold
(hot) in your living room
Possible cause Corrective action
The desired room temperature is
too low (high).
Increase (decrease) the desired
room temperature. See "3.3.2To
change the desired room
temperature"on page6.
If the problem recurs daily, do
one of the following:
▪ Increase (decrease) the room
temperature preset value. See
the user reference guide.
▪ Adjust the room temperature
schedule. See "3.6 Schedule
screen: Example"on page7.
The desired room temperature
cannot be reached.
Increase the desired leaving
water temperature in accordance
with the heat emitter type. See
"3.3.3To change the desired
leaving water temperature"on
page6.
Possible cause Corrective action
The weather-dependent curve is
set incorrectly.
Adjust the weather-dependent
curve. See the user reference
guide.
6.3 Symptom: The water at the tap is
too cold
Possible cause Corrective action
You ran out of domestic hot
water because of unusual high
consumption.
If you immediately need domestic
hot water, activate the DHW tank
Powerful operation. However,
this consumes extra energy. See
"3.4.4Using DHW powerful
operation"on page6.
If the problems recurs daily, do
one of the following:
▪ Increase the DHW tank
temperature preset value. See
the user reference guide.
▪ Adjust the DHW tank
temperature schedule.
Example: Program to
additionally heat up the
DHW tank to a preset value
(Eco setpoint = lower tank
temperature) during the day.
See "3.6 Schedule screen:
Example"on page7.
The desired DHWtank
temperature is too low.
6.4 Symptom: Heat pump failure
When the heat pump fails to operate, the backup heater can serve
as an emergency heater and either automatically or non-
automatically take over the heat load.
▪ When auto emergency is set to Automatic and a heat pump
failure occurs, the backup heater will automatically take over the
heat load and the domestic hot water production.
▪ When auto emergency is set to Manual and a heat pump failure
occurs, the domestic hot water and space heating operation will
stop and need to be recovered manually via the user interface. To
recover operation manually, go to the Malfunctioning main
menu screen, where the user interface will then ask you to confirm
whether the backup heater can take over the heat load or not.
When the heat pump fails, or will appear on the user
interface.
Possible cause Corrective action
Heat pump is damaged. See "6.1To display the help text
in case of a malfunction"on
page11.
INFORMATION
When the backup heater takes over the heat load,
electricity consumption will be considerably higher.
6.5 Symptom: The system is making
gurgling noises after
commissioning
Possible cause Corrective action
There is air in the system. Purge air from the system.(a)

Possible cause Corrective action
Various malfunctions. Check if or is displayed
on the home screen of the user
interface. See "6.1To display the
help text in case of a
malfunction"on page11 for more
information about the
malfunction.
(a) We recommend to purge air with the air purge function of
the unit (to be performed by the installer). If you purge air
from the heat emitters or collectors, mind the following:
WARNING
Air purging heat emitters or collectors. Before you
purge air from heat emitters or collectors, check if or
is displayed on the home screen of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room where you want to
purge air is sufficiently ventilated. Reason: Refrigerant
might leak into the water circuit, and subsequently into
the room when you purge air from the heat emitters or
collectors.
7 Disposal
NOTICE
Do NOT try to dismantle the system yourself: dismantling
of the system, treatment of the refrigerant, oil and other
parts MUST comply with applicable legislation. Units
MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.
