To change the desired room temperature
During room temperature control, you can use the room temperature
setpoint screen to read out and adjust the desired room temperature.
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.
Example:
1 Go to the [1]: Room menu.
Tt
You can read out the desired and actual room
temperature in the center of the setpoint screen.
To change the desired leaving water
temperature
The leaving water is the water that is sent to the heat
emitters. The desired leaving water temperature is set by
your installer in accordance with the heat emitter type.
Only adjust the leaving water temperature settings in case
of problems.
You can use the leaving water temperature setpoint screen to read
out and adjust the desired leaving water temperature.
1 Go to the 2: Main zone or 3:Additional zone menu.
You can read out the desired and actual leaving
water temperature in the center of the setpoint

In scheduled + reheat mode, the domestic hot water control is the

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

▪ 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.

Tips about DHW tank temperature
System
▪ Use a weekly schedule for your normal domestic hot water needs
(only in scheduled mode).
Indoor unit type (read only)
Backup heater type [9.3.1]
▪ Program to heat up the DHW tank to a preset value (Storage
comfort = higher DHW tank temperature) during the night,
because then space heating demand is lower.
Domestic hot water [9.2.1]
Emergency [9.5]
Number of zones [4.5]
▪ If heating up the DHW tank once at night is not sufficient,
program to additionally heat up the DHW tank to a preset value
(Storage eco = lower DHW tank temperature) during the day.
Backup heater
Voltage [9.3.2]
Configuration [9.3.3]
▪ 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.
Capacity step 1 [9.3.4]
Additional capacity step 2 [9.3.5]
(if applicable)
▪ 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.

This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Energy saving tips
Global warming potential (GWP) value: 675
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO2-equivalent) is used to determine the maintenance
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Tips about room temperature
Please contact your installer for more information.
▪ 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.
WARNING: FLAMMABLE MATERIAL
▪ 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.

WARNING
6.3
▪ 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.
Symptom: The water at the tap is
too cold
Possible cause
You ran out of domestic hot
water because of unusual high
consumption.
The desired DHW tank
temperature is too low.
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.
If you can wait, overrule
(increase) the active or next
scheduled desired temperature
so that more hot water will be
produced exceptionally.
If the problems recurs daily, do
one of the following:
Turn off any combustible heating devices, ventilate the
room, and contact the dealer from which you purchased
the unit.
▪ Increase the DHW tank
temperature preset value.
Do not use the unit until a service person confirms that the
portion from which the refrigerant leaked is repaired.
5.2
Corrective action
If you immediately need domestic
hot water, activate the DHW tank
Powerful operation. However,
this consumes extra energy.
▪ Adjust

Troubleshooting
6.1
To display the help text in case of
a malfunction
When the heat pump fails to operate, the backup heater and/or
booster 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:
▪ For EHVH/X: The backup heater will automatically take over the
heat load and domestic hot water production
In case of a malfunction, the following will appear on the home
screen depending on the severity:
▪
▪ For EHBH/X: The backup heater will automatically take over the
heat load, and the booster heater in the optional tank will
automatically take over the domestic hot water production.
