5 Energy visualisation
The user interface is able to graphically display energy statistics for:
▪ produced energy: energy produced by the heat pump.
▪ consumed electricity: recorded by an electricity meter or, when
none is installed, calculated by the interface itself based on an
internal calculation.
▪ consumed gas: only recorded when an external gas meter is
installed. Note that the values recorded by the meter may differ
from those shown on the boiler.

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.

Maintenance and service

7.1 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 indicated on the gas boiler is
above 1 bar. Switch off the boiler to see the pressure on the main
display of the gas boiler. Ignore the error that appears on the user
interface. When you turn the gas boiler back on, the error will
disappear.
▪ Make sure that electricity and gas prices defined in the user
interface are up-to-date.
Refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent
gases into the atmosphere.
Refrigerant type: R410A
Global warming potential (GWP) value: 2087.5
NOTICE
In Europe, the greenhouse gas emissions of the total
refrigerant charge in the system (expressed as tonnes
CO -equivalent) is used to determine the maintenance
2
intervals. Follow the applicable legislation.
Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in
kg] / 1000
Please contact your installer for more information.
