Handling
Thischapterisintendedforyou,theenduseroftheproduct,anddescribeshowyournewheating
systemfunctionsandyouroptionsforadjustingthesettingsinordertomakeyourhouseas
comfortableaspossiblewiththebestcost‐efficiency.
Askyourinstallertogothroughthesystemwithyou,andaskfortheregistrationformtofillinafter
theinstallationiscompleted.
How the Exotic Compact works
TheExoticCompactconsistsof2parts:atankcomponentandaheatpumpcomponent.Thetank
holdsthewaterwhichisusedtoheatyourhouseandtosupplyhotwaterforshowering,etc.Since
thewatertoheatyourhouse(radiators/underfloorheating)doesnotneedtobeequallyhotallthe
time,thetankisdividedintotwosections,alowersectionandanuppersection.Thereisaplate
betweenthesetwosections,whichensuresthatthetankcanmaintaintwodifferenttemperatures.
Lower tank section
Thelowertanksectionisusedprimarilytoheatthehouse,butalsotopreheatthecoldwaterthat
willbecomehotwaterintheExoticCompact.Dependingonyourheatingsystem,differentwater
temperaturesarenecessaryatdifferentoutdoortemperatures.Ifitiswarmoutside,thesystemdoes
notneedveryhotwater.Conversely,ifitisverycoldoutside,highertemperaturesareneededto
heattheinsideofthehouse.Thetemperatureofthewaterthatissenttoyourradiators/underfloor
heatingisdeterminedbytheso‐calledheatingcurve.Youcansetthiscurveyourself.Itisimportant
tomakesurethattheheatingcurveissetproperly‐foryourowncomfort,butalsotoensurethe
overallefficiencyoftheheatingsystem.
Upper tank section
Theupperpartofthetankisusedprimarilytoheatyourhotwater.Becauseyoualwayswanttohave
hotwateravailable,theheatpumpkeepsthissectionwarmregardlessoftheoutdoortemperature.
Youcansetthetemperatureinthispartoftankyourself.Thehigherthetemperature,thewarmer
thehotwater,buthotterwaterneedsmoreenergyandisthereforemoreexpensive.
Hot water
ExoticCompactusesaspecialtechniqueforheatingthehotwaterthroughaspecialexchanger.
Whenyoustarttolosehotwater,e.g.duringshowering,waterisdrawnfromboththelowerandthe
uppertanksectionsthroughtheexchanger,wherethecoldwatercomesinandisheatedintohot
water.Thereisnoriskoflegionnaires'diseasebecausethehotwaterisnotstored,ratheritis
produceddirectlyasneeded.
The heat pump
TheheatpumpisatthebottomoftheExoticCompactandisconnectedtoboththeupperandlower
tanksections.Thismeansthattheheatpumpheatseithertheuppertanksectionorthelowertank
section,dependingonrequirements.Theheatpumpisalsoconnectedtotheso‐calledbrinesystem.
Thebrinesystemisthesystemwhereenergyiscollectedtoheatthewaterinthetankusingtheheat
pump.Energycanbedrawnfromeitheraborehole,thegroundoralake.
Electric heater
ExoticCompacthasanintegratedelectricheaterintheuppersectionofthetank.Thisisusedifthe
energyfromtheheatpumpisnotsufficientorifthereisafaultintheheatpump.

Heating curve
Thischapterdescribeshowtheheatingforthehouseworksandhowyoucanadjusttheso‐called
heatingcurvetoachievemaximumsavingswithoutsacrificingcomfort.
Heating requirements for the house
Howyourhouseisbuilt,theclimateinyourarea,andwhattypeofheatingsystemyouhaveall
influencehowmuchenergyisneededtoheatit.
Therearemanyfactorsthataffectthetemperaturerequiredforyourheatingsystem.Forexample,if
itiscoldoutside,thehousewillneedmoreenergy/heating.Ifyouhaveanoldradiatorsystem,the
radiatorswillrequirewarmerwaterthanmodernradiatorstogenerateenoughheat.Ifyouhavean
underfloorheatingsystem,thewaterwillnotneedtobeashottoachievesufficientheating.
Basedonalloftheseparameters,whichvaryfromhousetohouse,thesettingswillbeuniqueineach
case.Wecallthistheheatingcurve.

Insimpleterms,theheatingcurvecanbedescribedastherelationshipbetweentheoutdoor
temperatureandthetemperature(flowline)thatyourheatingsystemrequires‐seethediagram
below.Youcanadjusttheheatingcurveinmanydifferentwayssothatitissuitedpreciselyforyour
house,andwewillreviewtheseinthischapter.

Remember!Ahouseheatingcurvethatissetproperlycansavealotofmoneyovertheyear.

Setting the curve
Thereare3basicsettingsfortheheatingcurve,pointsA,BandC.Withthese3points,youcanadjust
thegradientandverticalposition.
Theaimisalwaystosetthecurveaslowaspossible.

Point APointAdescribesthetemperatureofthewatertobesenttothe
radiatorsiftheoutdoortemperatureis‐15°C.Thefactorydefault
settingforthisitemis55°C.Inotherwords,whenitis‐15°Coutside,
theExoticCompactunitsends55°Cwatertotheradiators.
Whenyouadjustthispoint,youchangetheangleoftheentireheating
curve.Thebiggestchangesoccurwhenoutdoortemperaturesarecold‐
seethegraphbelow.

Ifyoufeelthatthereisn'tenoughheatwhenitisbelow‐5°Coutside,
buttherearenoproblemswhenitiswarmer,youcanadjustthispoint

thegradientforanyparticularoutdoortemperature,ratheryouadjust
thecurvefortheentireoutdoortemperaturerange.Thefactorydefault
settingis0°C,i.e.nomovementatall.Ifyouincreasethisvalue,the
curvemovesupwards,i.e.becomeswarmer,andifyoureducethis
value,thetemperaturedrops.
Thissettingisprimarilyusedwhenyoufeelthatitistoocold(orwarm)
regardlessoftheoutdoortemperature.

Limiting the heating curve
PointsA,BandCareallusedtosetthecurveindifferentpositions.Therearealso3otherwaysfor
adjustingthecurve.Basementheating,underfloorheatingandroomsensors.These3settingsdonot
affectthegradientorthepositionoftheheatingcurve.Instead,theyrestrictthecurveandallowyou
tosetaminimumandmaximumtemperaturethatissenttotheheatingsystem.
Basement heatingBasementheatingallowsyoutocancelthefunctiondescribedinpointC,
"heatoff",whichmeansthattheExoticCompactunitstopssending
watertoyourheatingsystem.Ifyouactivatebasementheating,Exotic
Compactwillcontinuetosendwateratthetemperatureyouset,evenif
theoutdoortemperatureishigh.
Activatebasementheatingifyoudon'twanttheheatingtobeturned
offevenifitiswarmoutside.Thisappliesprimarilywhenyouhavea
basementthatneedsacertainamountofheatingeveninthe
summertime,orabathroomwithunderfloorheatingcoilsthatyou
wanttokeepwarminthesummertimeaswell.

Room sensorAroomsensorisasensorplacedinacentrallocationinyourhouse,which
providesinformationtotheExoticCompactunitregardingtheambient
temperature.Dependingonhowyourhouseisdesigned,aroomsensormay
workmoreorlesseffectively.Ifyouhavealargehousewithmanysmall
rooms,itcanbedifficulttouseroomsensorsbecauseitmaybetoocoldor
hotintheroomsthatarefarwayfromthesensor.Ifyouhaveanopenplan
house,roomsensorsarerecommended,bothforthesakeofcomfortand
fromanenergyefficiencystandpoint.
Ifyouhavearoomsensorinstalled,youcandecidewhetheritshouldbe
usedtocompensatetheheating,i.e.beallowedtoaffecttheheatingcurve.
Ifitbecomeswarmerthanyouroriginalsetting,theExoticCompactwill
reducetheheattoyourradiators/underfloorheatingsystem.Thegreater
thedifference,thecoolerthewaterthatissentout.Thisadjustmentwill
takeplacecontinuously,whichmeansthattheappearanceoftheheating
curvewillbeconstantlychanging.Foreach1/10ofadegree(0.1°C)thatthe
currentroomtemperaturedeviatesfromthesettemperature,the
temperatureinyourheatingsystemdropsbyapproximately4°C.
Block temporarily Thebuttonplacedontheroomsensorcanbeusedfordifferentfunctionsof
yourownchoice.Oneofthesefunctionsistotemporarilyblockthesensors
impactontheheatingcurve.Thisfunctionisofinterestifyouforexample
haveanopenfireplaceplacedinthesameroomasthesensor.Whenyou
addheattotheroomwiththefireplacethesensorwillstoptheheattothe
completeheatingsystem,i.e.allroomswillbeaffected.However,ifyouuse
thisfunctionyoucansetatimedelayinhoursforblockingofthesensor
whenyouwanttousethefireplace.Whenyoupressthebuttonthe
activationwillbeconfirmedby2blinksfromthereddiode.Observethatyou
havetohavesetthisfunctionfirstinthemenu:”Settings”‐>”Forcustomer”‐

Remember!Theroomsensorcannotincreasetheheatingcurveifitbecomestoocold
insidethehouse.Ifitbecomestoocold,youneedtoincreasetheheatingcurve
manuallyaccordingtothepreviousinstructionsinthischapter.
Exampleoftheroomsensorfunction.Thesetvalueforroomtemperatureis21.0°C.Ifthe
temperatureinthehouserises,thetemperatureintheheatingsystemwillgraduallydecrease.

Why is the heating curve important?
Nowwehavegonethroughthesettingsfortheheatingcurve,andtheimportanceofproperlysetting
theheatingcurvehasbeenhighlighted.Whyisthissoimportant?
Well,theheatpumpdoesn'tactlikeaoil‐basedfurnace,woodstoveorelectricboiler,wherethe
temperaturedoesnothaveasgreatanimpactonefficiency.
Theeffectiveness/efficiencyoftheheatpumpiscalledtheCOPandisameasureofhowmuch
energyyougetbackinrelationtohowmuchyouputin.COP=3meansthatifyouputin1kWhof
energy,youget3kWhofenergybackout.
Theefficiency,COP,oftheheatpumpdependsonmanydifferentparameters,butthereisaclear
connectionbetweenthewatertemperatureintheheatpumpandCOP.Thehotterthewaterthat
theheatpumpmustproduce,thelowerthedegreeofefficiency,COP,andthelowerthecostsavings.
Thismeansthatinordertooptimiseyoursavings,theheatingcurveneedstobesetaslowas
possible.Iftheheatingcurveissettoohigh,theheatpumpgenerateswaterthatiswarmerthan
necessaryandthereforehasalowerdegreeofefficiency.

The best savings for your heating system come
from setting the water temperatures as low as
possible!

In practice
Itcantakealongtimetosetuptheperfecthouseheatingcurveforyourhouse,andyoumayneed
toadjustitanumberoftimes.Aboveall,itwillneedtobeadjustedwhentheoutdoortemperature
drops.
Thereareafewbasictipsthatshouldbefollowed.
Radiator thermostats
Allradiatorthermostatsshouldbecompletelyopenwhenyousetyouheatingcurve.Otherwise,the
riskisthattheExoticCompactunitwillsendoutwaterthatiswarmerthannecessary.
Adjustment
Withthethermostatscompletelyopen,tryreducingtheheatingcurveusingthesettingsinthis
chapter,e.g.heatingcurvepointB.Waitafewdaysandseewhetherthecomfortlevelissatisfactory.
Whenyoufindasettingwhereitissufficientlywarminthecoolestroominthehouse,youcanfine‐
tunethethermostatsontheradiatorsintheotherrooms.
Room sensors
Roomsensorsmakeadjustmenteasier,becausethesystemitselfdecreasestheheatingcurvewhen
necessary.
Rememberthatraisingtheroomtemperaturebyonedegreemeansthatapproximately3‐5°C
warmerwaterneedstobeproduced.


Hot water
Inadditiontoheatinginyourhome,havingdomestichotwateravailableisobviouslyalsoimportant.
TheExoticCompactprimarilyusestheheatpumpwithitsspecialexchangevalvetechnologyto
producehotwater.Youcaninfluencehowyourhotwaterisproduced,andyourchoicewillaffect
boththeamountofhotwaterandtheefficiencyoftheheatingsystem.
Justaswithheatforyourhouse,whichyoucanreadaboutinthepreviouschapter,thereisa
connectionbetweenthetemperatureofthehotwaterandthesavingsyoucanachieve.High
temperaturesalwaysmeanlowersavings.UsingExoticCompact'suniquehotwaterexchanger,you
canhaveagoodlevelofdomestichotwaterwithoptimalsavings.

How hot water is produced
TheExoticCompactdoesnothaveanycontainerorcoilswithhotwaterinsidethetank,butfreshhot
waterisproducedcontinuouslyusingaspecialhotwaterexchanger.Thisexchangeruseswaterboth
fromthelowertanksection,whichisoftensomewhatcooler,andfromtheuppertanksection,which
alwayshashotwater.Thelowertanksectionpreheatstheincomingcoldwater,andtheuppertank
sectionisusedtotopupthetemperaturesothatthewaterisreallyhot.TheExoticCompactonly
heatshotwaterwhenyouareusingit.Aflowmonitorsenseswhenthehotwaterisbeingusedand
startsapumpthatsendswaterfromthelowertanksectionthroughtheexchangerthatheatsthe
warmwater.Seethediagrambelow.

Hot water - settings
YoucanuseanumberofsettingstoinfluencehotwaterproductioninyourExoticCompact.
Economy or priority
Onebasicdecisiontobemadeiswhetheryouwanttohaveextradomestichotwaterorwhetheryou
wanttoprioritisesavingasmuchmoneyaspossible.Inmostcases,theeconomysettingprovides
enoughhotwater,butifyouhavelargebathtubs,ajacuzzi,etc.youmaywanttoselectthepriority
hotwatersetting.

Remember!Alwaysstartwiththeeconomysettingandseewhetherthisprovidesenough
hotwaterforyourneeds.

Economy
TheeconomysettingmeansthatthehotwaterpumpintheExoticCompactunithasmoretimetotry
toheatthewaterintheuppertank.WhenyouusehotwaterfromtheExoticCompactunit,primarily
whenshoweringorfillingthebathtub,thetemperatureintheupper(andlower)sectionwilldrop.
Theheatpumpwillstartwhenthetemperaturehasdroppedafewdegrees.Ifthetemperature
continuestodrop,theelectricheatermayalsoneedtostart.Ifyouusetheeconomysetting,the
temperatureisallowedtodropfurtherbeforetheelectricheaterisallowedtostart.Thisgivesthe
heatpumptheoptionofheatingupthewaterinstead,whichisthemosteconomicalsolution.
Priority
Theprioritysettingmeansthattheelectricheaterstartssoonerifthetemperatureintheupper
sectionofthetankdrops.Thisprovidesbetterhotwaterperformance,butitalsocostsmoretoheat
thewater.

Extra hot water
Thebuttonplacedontheroomsensorcanbeusedfordifferentfunctionsofyourownchoice.Oneof
thesefunctionsisthefunction“Extrahotwater”.Thefunctiongivesthepossibilitytotemporarily
increasethehotwaterperformanceoftheExoticCompact.Thisfunctioncanbeusedifforexample
manypeopleneedtoshowerquicklyaftereachother,manyshowersusedatthesametimeorifa
biggerbathtub/Jacuzzishouldbefilled.
Whenyoupressthebuttontheactivationwillbeconfirmedby2blinksfromthereddiode.Observe
thatyouhavetosetthisfunctionfirstinthemenu:”Settings”‐>”Forcustomer”‐>Functionbutton”.
Furtherinformationinthechapter“Menufunctionbutton”
Observethatitwilltakeatleast15‐30minfortheheatpumptoincreasethetanktemperature.
Noelectricheaterisusedforthisfunctionwhichimplieslowercosts.


Upper tank temperature
Youcansetthetemperaturethatyouwanttobemaintainedintheuppertankyourself.Asmentioned
previouslyinthischapter,ahighertemperaturesettingcostsmore,butthelevelofcomfortissomewhat
better.Ifyousetthetemperaturetoaveryhighlevel,above60°,thismaymeanthattheheatpumpcannot
managetoheattheuppertankbyitselfbutneedstheelectricheatertohelpout.
Thefactorydefaultsettingfortheuppertanktemperatureis55°C.Tryreducingthistemperaturesettinga
fewdegreesandseewhetherthehotwatertemperatureissatisfactoryforyourrequirements.Thisallows
youtosaveevenmoremoney.
Ifyourhouse(heatingsystem)needswaterthatiswarmerthanthetemperaturethatyousetontheupper
tanksection,theheatingcurvefortheuppertankwillbeapplied.
