SETUP:
IMPORTANT:Makesuretoobservethecorrectpolaritywheninsertingbatteries.The"+"
markingsonthebatteriesmustlineupwiththediagramsinsidethebatterycompartments.
Insertingthebatteriesincorrectlymayresultinpermanentdamagetotheunits.Duringthe
setupprocess,placethewirelessdisplayandtheoutdoorsensorsonasurfacewith5‐10feet
betweenthesensorsandthedisplay.OnlyuseAlkalineBatteries,rechargeablebatteriesmay
notwork.
1. Itisimportanttoallowsufficientlighttoreachthesolarpanelwhile
activatingthewindsensor.Makesurethelightsareoninthesetup
roomandthesolarpanelisfacinga60Wlightbulborbrighter.Ensure
thepanelisnotcovered,andremovetheblackprotectivefoilonthe
solarpanel.Removethetapecoveringtheresethole.Usethe
providedplasticresetrodtogentlypresstheresetbuttononceinthe
holeonthebottomofthesensor.
2. Inserttwo"AA"sizebatteriesintotherainsensorwiththecorrect
polarity.
3. Inserttwo"C"sizebatteriesintothethermo‐hygrosensorwiththecorrectpolarity.
Waittwominutesforthesensorstotalktoeachother.
4. Insertthree"C"sizebatteriesintothewirelessdisplaywiththecorrectpolarity.Donot
pressanybuttonfor10minutes.
NOTE:Everytimethewirelessdisplayreceivesdatafromthesensors,thewirelessicons
willblinkonceandthenreturntosolidifthelasttransmissionwassuccessful.Awind
speedorrainfallamountthatreads"0"doesnotmeanreceptionfailure,itmeansthat
therewasnowindorrainatthetimeofthelastmeasurement.Thethermo‐hygro
sensorsyncswiththewindandrainsensorsandsendsalloutdoorsensordatatothe
display.Thethermo‐hygrosensortriesfor4minutestosynctothewindsensorand
then4minutesfortherainsensor.Ifnotsuccessfulwithin4minutes,thethermo‐hygro
sensorwillstoplookingfortheothersensors.

Page|8
5. Setuptroubleshooting:Ifthesensordatafailstodisplayforanyoftheoutdoorsensors
within10minutes,(“‐‐‐“isdisplayed),removethebatteriesfromallunitsfor1minute
andstarttheSetupprocedureagainatStep1.

MOUNTINGTHESENSORSANDPLACEMENTOFTHEWIRELESSDISPLAY:
IMPORTANT:Ensurethatallofthesensordatacanbereceivedattheintendedmounting
locationsbeforeyoudrillmountingholes.Thewindandrainsensorshaveawirelessrangeof
200‐feet&thethermo‐hygrosensorhasawirelessrangeof200‐feet.Keepinmindthatthe
rangesequatetoanopenairscenariowithnoobstructions.Eachobstruction(roof,walls,
floors,ceilings,etc.)willreducetherange.



Thethermo‐hygrosensormeasuresoutdoortemperature&humidityandcollectsthedata
fromthewindandtherainsensors.Itsendsalloutdoorweatherdatatothewirelessdisplay,
sothethermo‐hygrosensormustbewithinthe200‐footwirelessrangeofthewirelessdisplay.
Thisallowsthewindandrainsensorstobeplacedrelativetothethermo‐hygrosensorrather
thanthewirelessdisplay.SeeWirelessDataDiagramabove.
Thewindandrainsensorsmustbemountedwithinthe200‐footwirelessrangeofthe
thermo‐hygrosensorandonthesamesideofthehouse.
Thewirelessdisplaymustbewithinthe80‐footwirelessrangeoftheUSBtransceiverto
sendweatherdatatothePC.
Inaddition,915MHzsensorstransmitbetterataminimummountedheightof6feet.
Ifthesensorwirelessicons dropfromthedisplayasyoumovethemintotheirintended
locations,thesensorsmaybetoofarfromthewirelessdisplay.Trymovingthewirelessdisplay

Page|9
orthesensorscloserandwaitafewminutestoseeifthewirelessicons displayagain.Ifthe
wirelessicons arestillnotdisplayedafterre‐positioningthesensorsorthewirelessdisplay,
pressandholdthe▲UPARROWkeyfor2secondstore‐synchronizethewirelessdisplaywith
thesensors.
WINDSENSOR
Thewindsensormustbeinstalledwiththefrontofthesensor(thesolarpanel)facingtrue
South,orthereportedwinddirectionwillnotbeaccurate.Mountwithinthe200‐footwireless
rangeofthethermo‐hygrosensorandonthesamesideofthehouse.Theroofmayormaynot
beanidealmountinglocation.Securethemainunittotheshaftofthemastholder.Usethe
right‐angleadaptorifthewindsensorwillbemountedonahorizontalmastorsurface.
FastenthewindsensortoasuitablemastusingthetwoU‐bolts,washersandnutsincluded.
Note:Mountthewindsensorontoamast,ataminimumheightof6feet,sothewindcan
reachthesensorunobstructedfromalldirectionsforanaccuratereading.Theidealmastis
between0.62"and1.3”indiameter.ThewindsensorDOESNOThavereplaceablebatteries;it
consumessolarpowerandchargestheinternalbatterypackautomatically.
Note:Donotopenthewindsensor.Thiswillvoidthewarranty.
RAINSENSOR
Therainsensorshouldbemountedonalevelsurfaceinanopenareawithinthe200‐foot
wirelessrangeofthethermo‐hygrosensorandonthesamesideofthehouse.Mounttherain
sensoratleast6feetoffthegroundandlevelforoptimumwirelesstransmission.Therain
sensorshouldbeaccessibletoallowforperiodiccleaningofdebrisorinsects.
THERMO‐HYGROSENSOR
Thethermo‐hygrosensoris"weatherresistant",butnot"waterproof".Toensureanextended
lifeforthesensor,mountitinasemi‐coveredplaceoutoftheelementsataminimumheightof
6feet.Anideallocationforthethermo‐hygrosensorisundertheeavesontheNorthsideof
thehousetoavoidtheeffectsofsunlight.Mountthesensor18"downfromtheeavesto
ensureoptimumperformance.Thiswillassurethetemperatureoftheaircomingoutofthe
atticwillnotaffectdatacollectedbythesensor.
Towallmountthethermo‐hygrosensor,fixthewallholderontothedesiredwallusingthe
includedscrews,plugthesensorfirmlyintothewallholderandreplacetheraincoverifitisnot
alreadyinplace.NOTE:Aftermountingtheunits,iftheweatherdataisnotreceived,pressand
