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.
