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.

▪ Adjust the room temperature
schedule.
Thedesiredroomtemperature
