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 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 (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.
