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.

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.

6 Troubleshooting
6.1 Symptom:Youarefeelingtoocold
(hot)inyourlivingroom
Possiblecause Correctiveaction
Thedesiredroomtemperatureis
toolow(high).
Increase(decrease)thedesired
roomtemperature.
Iftheproblemrecursdaily,do
oneofthefollowing:
▪ Increase (decrease) the room
temperaturepresetvalue.
▪ Adjust the room temperature
schedule.
Thedesiredroomtemperature
cannotbereached.
Increasethedesiredleaving
watertemperatureinaccordance
withtheheatemittertype.
6.2 Symptom:Thewateratthetapis
toocold
Possiblecause Correctiveaction
Youranoutofdomestichot
waterbecauseofunusualhigh
consumption.
Ifyouimmediatelyneeddomestic
hotwater,activatetheDHWtank
boostermode.However,this
consumesextraenergy.
Ifyoucanwait,overrule
(increase)theactiveornext
scheduleddesiredtemperature
sothatmorehotwaterwillbe
producedexceptionally.
Iftheproblemsrecursdaily,do
oneofthefollowing:
▪ Increase the DHW tank
temperaturepresetvalue.
▪ Adjust the DHW tank
temperature schedule.
Example: Program to
additionally heat up the
DHW tank to a preset value (
Storage eco = lower tank
temperature)duringtheday.
ThedesiredDHWtank
temperatureistoolow.

6.3 Symptom:Heatpumpfailure
Whentheheatpumpfailstooperatethebackupheatercanserveas
an emergency heater and either automatically or nonautomatically
take over the heat load. When auto emergency is activated and a

over the heat load. When a heat pump failure occurs and auto
emergency is not activated, the domestic hot water and space
heatingoperationswillstopandneedtoberecoveredmanually.The
userinterfacewillthenaskyoutoconfirmwhetherthebackupheater
cantakeovertheheatloadornot.Whentheheatpumpfails, will
appearontheuserinterface.
Possiblecause Correctiveaction
Heatpumpisdamaged. ▪ Press toviewadescription
oftheproblem.
▪ Press again.
▪ Select  to allow the backup
heater to take over the heat
load.
▪ Call your local dealer to get
theheatpumpfixed.
INFORMATION
When the backup heater takes over the heat load,
electricityconsumptionwillbeconsiderablyhigher.
