Ventilationhastobeconstantfortheindoorairtostayhealthy
forthebuilding’soccupants.Evenforlongerholidays,itisnot
advisabletostoptheventilation,becausetheindoorairwillbecome
stuffyandduringtheheatingseason,theindoorairhumiditymay
condenseintheventilationductworkandstructures,causing
moisturedamage.
Youcancontrolandautomatetheventilationunitoperationinthe
following ways:
• ByusingaDigitalControllerinstalledinthebuilding
• ThroughtheAdroitHomelocalnetworkconnectionandthe
Webinterface
• ThroughtheAdroitCloudServiceandtheWebinterface
• Througharemotemonitoringserviceorbuildingautomation
system(BMS)byusingvoltagesignalsorModbusmessages
Therequiredventilationmayalsobeadjustedautomaticallywith
theoptionalroommountedbetweencarbondioxideandhumidity
sensors.Inthiscase,ventilationremainsoptimalevenifthe
dwellingisunoccupied.
Byusingtheweekclock,youcancreatejusttherightventilationfor
yourindividuallifestyle.
WARNING
Theunitisnotintendedforusebychildren(under8years)orby

INTRODUCTION
INTRODUCTION
Each ventilation unit has two control settings
available,basicandexpert.Thebasicsettingsare:
• Userinterfacelanguage.
• Timeanddate.
The expert settings are:
• Systemadministratorpassword.Theinstaller
has given you the system administrator
password.
• Possibleparentalcontrols.
• Fansettings.
• Userprolesettings,suchasthetemperature.
Settingscanbechangedatalaterdateifrequired.
STARTING THE UNIT
Ifyouarestartingtheventilationunitforthersttime
orafteranymaintenanceprocedure,whentheunit
startsup,thediagnosticdisplaywillappearfora
fewsecondsuntiltheAthomeprolemainscreenis
opened.
Iftheunitisswitchedofffromthecontroller,youcan
restarttheventilationunitbypressinganybuttonon
thecontroller.
We recommend that the latest version always to
beused.Checkanddownloadthelatestversionat
https://www.airowadroitcontrol.com/eitherbeforeor
immediatelyaftersetup.
The current software version of the ventilation unit
is shown on the controller display when the unit
is connected to the mains or factory settings are
restored.Alternatively,thecurrentsoftwareversion
canbecheckedfromtheUnitinformationdisplayof
theServicemenu.
UPDATING THE UNIT SOFTWARE
Disconnecttheventilationunitfromthemains
electricalsupply.orturnoffthefuse.
Connectthecomputertothedigitalcontrollerofthe
ventilationunitusingaUSBMicroBconnector.
Starttheventilationunit.AUSBsignwillappearon
thedisplayofthecontroller.Thecontrollercannotbe
usedwhenitisconnectedtothecomputer.
NOTE
Therstlaunchoftheunitmaytakeawhile,
as the controller will format its software and
verifythatithasthelatestsoftwareversion.
NOTE
However,itisrecommendedthatthe
ventilationbekeptturnedON without
disruptions.
Transfertheupdateleyouhavedownloadedonto
theventilationunit.CopytheupdateleHSWUPD.
BIN
(Pleasenote!Donotalterthelename!)you
havedownloadedattherootofthecontroller(the
controllerwillbedisplayedonyourcomputerasa
massmemoryoraremovablediskdrive).Whenthe
lehasuploadedontothecontroller,removethe
USBcable.Next,thecontrollerwilltakeawhileto
loadtheupdate.Thecontrollerwillnowstarttoload
theupdateleontothemotherboard.Thiscantake
severalhours.Thecontrollerwillremainturnedon,
butitisrecommendedthatthecontrollerwillnotbe
usedduringthattime.Whentheupdateisready,the
unitwillrestartautomatically.
TURNING THE UNIT OFF
Ifyouwanttoturnofftheventilationunit,proceedas
follows:
1. Select Settings > Turn unit off.
2. PresstheOKbutton.
3. Thesystemasksforconrmation.
4. PresstheOKbutton.

WALL MOUNTING
Notethefollowingbeforemounting:
• DV145Shouldnotbepositionedinanareathatfallsbelow
+10°C.
• Avoidmountingtheunitonahollow,echoingpartitionwallor
onabedroomwall.Takingsoundtransmissionprecautionsis
recommended.
• Theminimumdistancebetweenthetopoftheunitandthe
nishedceilingsurfaceis30mm.Notethatduringmountingthe
unitrises10mmhigherthanthenalheight.
• It is recommended that the unit is not positioned in sound
sensitive areas unless some acoustic deadening measures are
taken.
MounttheDV145onthewallwithamountingbracket,asshownin
theadjacentgure.Makesurethattheunitishorizontallylevelafter
mounting.
MEASURING TUBES
Theaccessorybagwiththeunitincludesfourairowmeasuring
tubes.Thesecanbeinsertedintheductstoallowforeasier
ventilationadjustment.
NOTE
MountDV145ontheoorrack,oronthewallwithamounting
bracket.

CONDENSING WATER
Intheheatingseason,theextractairhumidity
condensesintowater.Waterformationmaybe
abundantinnewbuildings,oriftheventilationislow,
comparedtothehumidityproductionofresidents.
Condensedwatermustbeabletogetoutofthe
unitwithoutobstruction.Checkinconjunctionwith
maintenance,forexample,duringtheautumnbefore
theheatingseasonbegins,thatthecondensate
collectiontraypositionedinsidetheunitatitsbase
isnotcloggedandthatthereisnoleakage.Youcan
checkitbypouringalittlewaterintothecondensate
collectiontraypositionedinsidetheunitatitsbase.
Clean,ifnecessary.Watermustnotbeallowedto
entertheelectricalsystem.
MOUNTING THE CONDENSING
WATER OUTLET
1. Pushthemainbodyofthecondensingwater
outletdownwardfromabove,throughtheholein
