▪ 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.

▪ Make sure the desired room temperature is NEVER too high (in

according to your actual needs. Each saved degree can save up
to 6% of heating/cooling costs.

▪ 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 and electric tariffs
may be 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:

Overview: Maintenance and

Symptom: The water at the tap is
too cold
Possible cause
The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.
You ran out of domestic hot
water because of unusual high
consumption.
The desired DHW tank
temperature is too low.
As end user, you have to:
Corrective action
If you immediately need domestic
hot water, activate the DHW tank
booster mode. However, this
consumes extra energy.
If you can wait, overrule
(increase) the active or next
scheduled desired temperature
so that more hot water will be
produced exceptionally.
▪ Keep the user interface clean with a soft damp cloth. Do NOT use
any detergents.
▪ Regularly check if the water pressure indicated on the manometer
is above 1 bar.
Refrigerant
If the problems recurs daily, do
one of the following:
This product contains fluorinated greenhouse gases covered by the
Kyoto Protocol. Do NOT vent gases into the atmosphere.
▪ Increase the DHW tank
temperature preset value.
Refrigerant type: R410A
Global warming potential value: 1975
▪ 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.
Periodical inspections for refrigerant leaks may be required
depending on the applicable legislation. Please contact your installer
for more information.
