INFORMATION
It is recommended NOT to use the selection of ([6
‑
0D]=0,
[A.4.1] Domestic hot water Setpoint mode=Reheat only) in
case of a domestic hot water tank without internal booster
heater.
The risk of space heating (cooling) capacity shortage/
comfort problems is significant (in case of frequent
domestic hot water operation, frequent and long space
heating/cooling interruption will happen).

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
▪ Make sure the number (available hot water for x persons) on the
DHW tank temperature home page is NOT higher than your actual
needs.
