3Overview
3.1 SystemFunction
TheMVA‐003,aself‐poweredthermostaticradiatorvalve,isanelectronicactuatorforconvection
radiators(standardvalvetypeM30x1.5).Itisdesignedforsingleroomtemperaturecontrol.
Forthispurpose,theactuatorismountedontheradiatorvalveandlinkedbyradio(EnOcean868
MHz) to a suitable room controller. A connection process is used to pair the devices and a
calibrationcycleallowstheactuatortoautomaticallyadaptitspositioningrangetotheindividual
radiatorvalve.
Withtheroomcontrollersetuptocontroltheactuator,theusercanconvenientlyconfigureroom
temperatureprofilesusingtheroomcontroller.Byloweringtheroomtemperatureduringperiods
ofabsence,heatingcostcanbereducedwithoutlossofcomfort.
Theactuatorcanbeoperatedin2modesasdescribedintheEnOceanequipmentprofileA5‐20‐
01.EitherwithSetpointvalue(%)orSettargettemperature(°C)usingitsinternaltemperature
controllerandambienttemperaturesensor.Itqueriestheroomcontrollerevery10minutesand

0%(valveclosedalltheway)and100%(valveopenalltheway)oranewSettemperaturevalue

Theactuatorgeneratestheenergyitneedsforoperation(running the motor and radio
communication)withabuilt‐inthermoelectricgenerator(TEG).Thisgeneratordrawsitsenergy
fromthedifferenceintemperaturebetweentheradiatorheatandambientairandthereforedoes
notneedanexternalpowersource,suchasabatteryorawallsocket,foroperation.

4.1 Defaultsettingondelivery
Onleavingthefactory,theself‐poweredactuatorisinmountingposition(valvepinisretractedor
canbepushedinallthewaywithoutforce).
Itsinternalenergystorageunitisfullycharged,sothereismorethanenoughenergyforsetting
theunitup.Whentheheatingsystemisrunning,theactuatorisautomaticallypoweredbythe
heatfromtheheatingcircuit.
4.2 Settinguptheactuatortoconnecttotheroomcontroller
Theactuatormustbecontrolledbyasuitableroomcontroller(supportingEnOcean
Equipment Profile EEP A5‐20‐01). The link between the two is established by a
bidirectionalconnectionprocess:
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.
SuccessfulcompletionoftheconnectionprocessisconfirmedbyasingleLEDflash.
Iftheconnectionoperationfails,theLEDflashesmultipletimes.Inthiscase,repeattheoperation.
Ifmultipleconnectionattemptsfail,checkwhethertheroomcontrollerisreadytoreceive,then
repeattheconnectionoperation.
NOTE:Double‐pressingthebuttonalwayscausesaconnectionrequesttobesent.Atthesame
time,itmakestheactuatormovetothemountingpositionandstopsnormalradiocommunication.

4.3 Settingthemountingposition
Pressingthebuttontwicewillalwaysbringtheactuatorintothemountingposition(valvepin
fullyretractedorcanbepushedinallthewaywithoutforce).
This is also the default‐position for storage and shipping, with power consumption being
minimizedsinceradiocommunicationisdisabledinthismode.
Theprimaryuseofthemountingpositionhowever,isattachmentandremovaloftheactuator
to/fromtheradiatorvalve(seeSection4.4).

1. Ifnecessary,removethemountedthermostatbyturningitsunionnutcounterclockwise.
Toloosenthenut,itcanbehelpfultosetthethermostattomaximum.
2. Removeanycontamination(dust,paint)thatmaybepresentonthepartofthevalvethat
