3Overview
3.1 SystemFunction
TheMVA‐003,aself‐poweredthermostaticradiatorvalve,isanelectronicactuatorforconvection
radiators(standardvalvetypeM30x1.5).Itisdesignedforsingleroomtemperaturecontrol.
Forthispurpose,theactuatorismountedontheradiatorvalveandlinkedbyradio(EnOcean868
MHz) to a suitable room controller. A connection process is used to pair the devices and a
calibrationcycleallowstheactuatortoautomaticallyadaptitspositioningrangetotheindividual
radiatorvalve.
Withtheroomcontrollersetuptocontroltheactuator,theusercanconvenientlyconfigureroom
temperatureprofilesusingtheroomcontroller.Byloweringtheroomtemperatureduringperiods
ofabsence,heatingcostcanbereducedwithoutlossofcomfort.
Theactuatorcanbeoperatedin2modesasdescribedintheEnOceanequipmentprofileA5‐20‐
01.EitherwithSetpointvalue(%)orSettargettemperature(°C)usingitsinternaltemperature
controllerandambienttemperaturesensor.Itqueriestheroomcontrollerevery10minutesand
reportsitscurrentvalvepinSetpointvalue.ItalsoreceiveseitheranewSetpointvaluebetween
0%(valveclosedalltheway)and100%(valveopenalltheway)oranewSettemperaturevalue
between0°Cand+40°C.Theactuator’sservomotorthenmovesthevalvepintothenewtarget
position.
Theactuatorgeneratestheenergyitneedsforoperation(running the motor and radio
communication)withabuilt‐inthermoelectricgenerator(TEG).Thisgeneratordrawsitsenergy
fromthedifferenceintemperaturebetweentheradiatorheatandambientairandthereforedoes
notneedanexternalpowersource,suchasabatteryorawallsocket,foroperation.

3.2 Properuseofthedevice
Theself‐poweredthermostaticradiatorvalveissuitablesolelyforcontrollingwater‐filled
heatingradiators.Anyotheruse–includingcontroloffloorheatingsystems‐isnot
permittedandcanresultindamage.
Donotdisassembleormodifyanypartoftheproduct.Itisimportanttocomplywiththe
safetynoticeincludedintheseoperatinginstructions.


UserGuide_MVA-003_V1_0517 Page 6
4Usage
4.1 Defaultsettingondelivery
Onleavingthefactory,theself‐poweredactuatorisinmountingposition(valvepinisretractedor
canbepushedinallthewaywithoutforce).
Itsinternalenergystorageunitisfullycharged,sothereismorethanenoughenergyforsetting
theunitup.Whentheheatingsystemisrunning,theactuatorisautomaticallypoweredbythe
heatfromtheheatingcircuit.

4.2 Settinguptheactuatortoconnecttotheroomcontroller
Theactuatormustbecontrolledbyasuitableroomcontroller(supportingEnOcean
Equipment Profile EEP A5‐20‐01). The link between the two is established by a
bidirectionalconnectionprocess:
First set the room controller to setup mode, as described in the instructions for the room
controller. Then double‐press the button on the actuator. After approximately 2 seconds, the
actuator will send a telegram to the room controller, which in turn confirms the reception.
SuccessfulcompletionoftheconnectionprocessisconfirmedbyasingleLEDflash.
Iftheconnectionoperationfails,theLEDflashesmultipletimes.Inthiscase,repeattheoperation.
Ifmultipleconnectionattemptsfail,checkwhethertheroomcontrollerisreadytoreceive,then
repeattheconnectionoperation.
NOTE:Double‐pressingthebuttonalwayscausesaconnectionrequesttobesent.Atthesame
time,itmakestheactuatormovetothemountingpositionandstopsnormalradiocommunication.
ForitsusewithRemoteManagementandCommissioningpleasegetintouchwithMicropelt(EH4
GmbH)
4.3 Settingthemountingposition
Pressingthebuttontwicewillalwaysbringtheactuatorintothemountingposition(valvepin
fullyretractedorcanbepushedinallthewaywithoutforce).
This is also the default‐position for storage and shipping, with power consumption being
minimizedsinceradiocommunicationisdisabledinthismode.
Theprimaryuseofthemountingpositionhowever,isattachmentandremovaloftheactuator
to/fromtheradiatorvalve(seeSection4.4).


UserGuide_MVA-003_V1_0517 Page 7
4.4 Attaching/removingthevalveactuatortotheradiator
Youdonotneedtointerruptthehotwatercircuitandwaterdoesnothavetobedrained,when
mountingorremovingtheactuator.Instead,theradiatorvalveremainsattachedtotheradiator
whiletheactuatorisscrewedontothevalve,typicallyinlieuofatraditionalthermostatichead.
Followthestepsbelow:
1. Ifnecessary,removethemountedthermostatbyturningitsunionnutcounterclockwise.
Toloosenthenut,itcanbehelpfultosetthethermostattomaximum.
2. Removeanycontamination(dust,paint)thatmaybepresentonthepartofthevalvethat
isgoingtoattachtotheactuator.
3. Besuretheactuatorisinmountingposition,e.g.thepiniseitherfullyretractedorcanbe
pushedinallthewaywithoutforce.Ifnot,thenpressthebuttontwiceandwaituntilthe
pinhasfullymovedinandthemotorstopsrunning.
4. Nowplacetheactuatorontheradiatorvalve.Screwontheconnectionnutandtightenit.
Notethatthisstepiscriticaltotheenergyharvestingperformance.
5. Theactuatorshouldnowrestfirmlyagainstthecontactsurfaceoftheradiatorvalve,
whichisthetransferpointoftheheatfluxtothethermoharvester.Aftermountingthe
actuator,trytogentlyrotateitbackandforthonthevalve.Itshouldnotmove.

4.5 Calibrationcycleandwirelessoperation
Afterattachingtotheradiatorvalve,theactuatorshouldbeinthemountingpositionwithwireless
communicationstopped.
Enternormaloperationoftheactuator,bypressingitsbuttononce.Thisinitiatesacalibration
cycle,inwhichthe0%positionofthevalveisdetermined.Followingthis,theactuatorrequestsa
positionfromtheroomcontroller,immediatelysettingthevalveopeningaccordingly.Wireless
operationisnowactive,withtheactuatoraskingtheroomcontrollerfornewinstructionsevery
10minutes.TheMVA‐003operatesin10secondscommunicationcycleimmediatelyfollowingis
mounting and activation. For this allows for quicker feedback and response for the first 10
minutes.Avoiddoublepressingthebuttonnow,sincethismayreturn the actuator to the
mountingposition,disruptingoperation.
During normal wireless operation, bidirectional communication with the room controller and
correctionofthevalveopeningtakesplaceevery10minutes.TheLEDremainsoff,unlessradio
communication fails, e.g. because the room controller is down. In this case, the LED flashes
multipletimes.Animmediateresponsecanbeextortedatanytimethroughpressingthebutton
onlyonce.
NOTE:Thepushbuttononthedeviceisneededforsetupandmounting/removalonly.
Frequentpressingofthebuttonresultsinexcessivevalveactuationwhichcandischarge
theenergystoragedeviceandsendtheunitintoalow‐powersleepmode.

5AdditionalInformation
5.1 PoweredbyEnergyHarvesting
Powertothe actuatorissuppliedby athermoelectricgenerator(TEG). This extractselectrical
energyfromthedifferenceintemperaturebetweentheheatingwaterflowandtheambientair.
Duringperiodsofradiatoractivity,excessenergyisbufferedintheinternalenergystoragedevice.
Theenergystoredduringthecoldermonthsoftheyearisusedtosupplementorreplacethe
harvester output in summer aswell as the spring and autumn transition periods. The storage
deviceissizedtopowertheunitthroughouttheyear,underconditions of normal heating
behavior.
Inraresituations,thereservoirmayrunlow.Theactuatorthenreportsthisconditiontotheroom
controllerandmovesthevalveintoaprotectedposition(50%valveopeningorcurrentposition,
ifthisisgreater).Theactuatorthenenterssleepmodeandwaitsforthestorageunittorecharge
from the thermoelectric generator. Once sufficient electrical energy has been gathered, the
actuatorresumesoperation.
Theabove‐mentionedsafepositionensuresthattheradiatorvalvedoesnotcalcifyinoneofits
endpositions,thatpipesdonotfreeze,andthatthethermoelectricgeneratorisbeingheatedonce
hotwaterstartsflowingagain.Whileinthesafeposition,theroomtemperaturemayfluctuate
slightly.

5.2 StatusindicatorsandLEDflashpatterns

5.3 Notesonradiooperation
5.3.1 Transmissionrange
Theradiotransmissionrangeislimitedbyboththedistancebetweentransmitterandreceiver,
andbyinterference.Indoors,buildingmaterialsplayanimportantrole.Majorreflectionsand
signallossesareduetometallicparts,suchasreinforcementsinwallsandmetallizedfoils,
whichareusedonthermalinsulationproducts.
Penetrationofradiosignals:

Inaddition,theangleatwhichthesignalentersthewallhastobeconsidered.Ashallowangle
increasestheeffectivewallstrengthaswellastheattenuationofthesignal.Wheneverpossible,
signalsshouldenterwallsperpendicularly.Alcovesshouldbecircumvented.
NOTE:Foradditionalinformation,refertotheEnOceanWhitePaper“EnOcean
WirelessSystems–RangePlanningGuide”.

5.3.2 Otherinterferencesources
Common sources of interference are devices that generate high‐frequency signals. These are
typicallycomputers,audio‐/videosystems,electronictransformersandballasts.Thedistanceof
theactuatortosuchdevicesshouldbemorethan0.5m.
5.3.3 Lossofcommunicationwiththeroomcontroller
Iftheactuatorcannotestablishadependableradiocommunicationwiththeroomcontroller,i.e.
more than 3 times in sequence the room controller does not receive a radio signal, then the
actuatorswitchestoareducedradiopattern.Thetypical10minuteradioperiodisextendedto
onetransmissioneveryhour,reducingtheenergyconsumptionwhileradiocontactisinterrupted.
Inaddition,theactuatorentersthesafepositionasdescribedinSection5.1.
Oncetheradiocontacttotheroom controller recovers, the actuator reverts to requesting
instructionsfromthecontrollerevery10minutes.
