7 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.

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 leaving water temperature

▪ In heating mode, a lower desired leaving water temperature results in lower

energy consumption and better performance. In cooling, the opposite is valid.

▪ Set the desired leaving water temperature in accordance with the heat emitter

type. Example: Underfloor heating is designed for lower leaving water

temperature than radiators and heatpump convectors.

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.
