About space operation modes
This unit is a heating only model. The system can heat up a space,
but NOT cool down a space.
However, if the kit EKHVCONV3 is installed, the system can cool
down a space, and you have to tell the system which space
operation mode to use: heating or cooling.
To tell the system which space operation to use, you can do the
following:
You can… Location
Check which space operation mode is
currently used.

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

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 (Storage
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
(Storage 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
5.1 Overview: Maintenance and
service
The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.
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
NOTICE
Applicable legislation on fluorinated greenhouse gases
requires that the refrigerant charge of the unit is indicated
both in weight and CO2 equivalent.
Formula to calculate the quantity in CO2 equivalent
tonnes: GWP value of the refrigerant × total refrigerant
charge [in kg] / 1000
Please contact your installer for more information.
WARNING: FLAMMABLE MATERIAL
The refrigerant inside this unit is mildly flammable.
WARNING
The appliance shall be stored in a 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.

number
Prerequisite: You switched the permission level to Advanced end
user.
1Go to [6.3.2]: > Information > Error handling >
Contact/helpdesk number.
6 Troubleshooting
6.1 To check the error history
Prerequisite: Only available if is displayed on the home pages.
1Go to [6.3.1]: > Information > Error handling > Error
history.
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Room thermostat control -
Using the room temperature
home pages"[47].
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 "3.5Schedules:
Example"[48].
The desired room temperature
cannot be reached.
Increase the desired leaving
water temperature in accordance
with the heat emitter type. See
"3.3.3Room thermostat control -
Using the leaving water
temperature home pages"[48].
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
booster mode. However, this
consumes extra energy. See
"3.4.5Using the DHWtank
booster mode"[48].
If you can wait, overrule
(increase) the active or next
scheduled desired temperature
so that more hot water will be
produced exceptionally. See "To
read out and overrule the active
or next scheduled desired
temperature (in scheduled mode
or scheduled + reheat
mode)"[48].
If the problem 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
(Storage eco = lower tank
temperature) during the day.
See "3.5 Schedules:
Example"[48].
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 activated and a heat pump failure
occurs, the backup heater will automatically take over the heat
load.
▪ When auto emergency is not activated and a heat pump failure
occurs, the domestic hot water and space heating operations will
stop and need to be recovered manually. 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, will appear on the user interface.
Possible cause Corrective action

▪ Press again.
▪ Select to allow the backup
heater to take over the heat
load.
▪ Call your local dealer to get
the heat pump fixed.
INFORMATION
When the backup heater takes over the heat load,
electricity consumption will be considerably higher.
