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.
WARNING

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.

4.5 Domestic hot water control
4.5.1 About domestic hot water control
Depending on the DHW tank mode (installer setting), you use a
different domestic hot water control:
▪Reheat only
▪Schedule + reheat
▪Schedule only
INFORMATION
In case of error code AH and no interruption of the
disinfection function occurred due to domestic hot water
tapping, following actions are recommended:
▪ When the Reheat only or Schedule + reheat mode
is selected, it is recommended to program the start-up
of the disinfection function at least 4 hours later than
the last expected large hot water tapping. This start-up
can be set by installer settings (disinfection function).
▪ When the Schedule only mode is selected, it is
recommended to program an Eco action 3hours before
the scheduled start-up of the disinfection function to
preheat the tank.

INFORMATION
When the DHW tank mode is reheat, the risk for capacity

frequent reheat operation, space heating/cooling function
is regularly interrupted.
4.5.3 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.

▪ Initially, the DHW tank temperature is the same as the
temperature of the domestic water entering the DHW tank
(example: 15°C).
▪ At 00:00 the DHWtank is programmed to heat up the water to a
preset value (example: Comfort = 60°C).
▪ During the morning, you consume hot water and the DHW tank
temperature decreases.
▪ At 14:00 the DHWtank is programmed to heat up the water to a
preset value (example: Eco = 50°C). Hot water is available again.
▪ During the afternoon and evening, you consume hot water again
and the DHWtank temperature decreases again.
▪ At 00:00 the next day, the cycle repeats.
4.5.4 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.

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 or for the tank. When the maximum
or minimum setpoint is reached, the curve flattens out.

5 Energy saving tips
Tips about room temperature
▪ Make sure the desired room temperature is NEVER too high, but
ALWAYS according to your actual needs. Each saved degree can
save up to 6% of heating 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:
underfloor 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 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 leaving water temperature
▪ In heating mode, a lower desired leaving water temperature
results in lower energy consumption and better performance.
▪ Set the desired leaving water temperature in accordance with the
heat emitter type. Example: Underfloor heating is designed for
lower leaving water temperature than radiators and heat pump
convectors.
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.
6 Maintenance and service
6.1 Overview: Maintenance and
service
