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/decrease the desired room temperature to
speed up space heating/cooling. The space will NOT heat up/cool
down faster.
▪ When your system layout contains slow heat emitters (example:
underfloor heating), avoid large fluctuation of the desired room
temperature and do NOT let the room temperature drop too low/
rise too high. It will take more time and energy to heat up/cool
down 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 until the next scheduled action.
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.
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 (
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
(
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.

equivalent.
Formula to calculate the quantity in CO
2
equivalent
tonnes:
