INFORMATION
Auto emergency: By default, backup heater operation
during emergency operation is NOT allowed. This means
that when a heat pump failure occurs the user needs to
manually confirm that backup heater may operate during
emergency. If the house is unattended for longer periods,
we recommend that setting [A.5.1.2] Emergency shall be
set to Automatic.

4 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:
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 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.
