Introduction
TheZXT‐120isaZ‐WavetoIRextenderforair‐conditioner(AC),
(Figure1),itworkswithanyZ‐Wavecompliantgatewayorcontroller
bytranslatingZ‐WaveThermostatCommandstoACIRcontrolcode.
UsercanselecttheIRcodefromthebuilt‐incodelibraryofZXT‐120,
oruselearningfunction,byusingZ‐WaveConfigurationCommands
accordingtotheparametertable.ZXT‐120isalsowithbuilt‐in
temperaturesensorwhichallowsgatewayorcontrollertogetthe
currentroomtemperature.

(beforeinclusionprocess).


canprovidetheflexibilityifthereisoutof5Vdcpowersource.Also,
usercanplacetheunitinanywhereathome.

AlwaysListeningnodetypeisfortheneedsoffastresponse
application.Itworkswith5Vdcpowersource.AlwaysListeningnode
canactasarepeater,whichwillre‐transmittheRFsignaltoensure
thatthesignalisreceivedbyitsintendeddestinationbyroutingthe
signalaroundobstacleandradiodeadspots.

ZXT‐120supportsNetworkWideInclusion(NWI)andExploreFrames.
ItalsosupportsZ‐Wavenetworkswithmultiplegatewaysand
controllers.LikeeveryZ‐Waveaccessory,userwillneedtoincludethe

theusercanuseeithertheprimarycontrollerorsecondarycontroller
toconfigureandsetuptheZXT‐120usingZ‐Wave’sconfiguration
