Daikin EHYHBH08AA Operating instructions

  • Hello! I've reviewed the operation manual for the Daikin Altherma hybrid heat pumps, models EHYHBH05AA, EHYHBH08AA, and EHYHBX08AA. This manual covers everything from basic operations like controlling heating and cooling to more advanced features like scheduling and energy visualization. I'm ready to answer your questions about your device and its features.
  • How do I switch between heating and cooling modes?
    How do I adjust the desired room temperature?
    How do I set the schedule?

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
