6 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.
TipsaboutDHWtanktemperature
▪ Makesurethenumber(availablehotwaterforxpersons)onthe
DHWtanktemperaturehomepageisNOThigherthanyouractual
needs.
▪ 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andelectrictariffs
maybe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
