1.Begininstallingtheheatingcablefromthethermostatorjunctionbox.Followthepatternmarkedontheoorplan(if
supplied).Pleasenotethethicknessofthefactoryspliceandcoldleadandplanaccordingly.
2.Unwindthecablefromthespool.SecureitusingtheTempZone™CableFixingStrips.Avoidbunchingthecableor
crossingoverotherpartsofthecable.
3.TheTempZone™FloorHeatingCable(Twin)shouldbeinstalledinauniformly-spacedserpentinepattern.Referto
either“ProductSelectionGuide--120V”or“ProductSelectionGuide--240V”insection9forspacinginformation.

indicatedonthecustomSmartPlan™suppliedwiththeorder(optional).
5.Routethepowerleadsfromtheoortothethermostatbox.Ifusingmultipleheatingcables,routethepowerleadsfrom
theoortoajunctionboxorthermostatboxinthewall.
NOTE: Leads should be protected at the point they leave the oor. Rigid metal conduit, intermediate metal
conduit, rigid nonmetallic conduit, electrical metallic tubing, or other means approved by local electrical codes
should be used.
6.Forinstallationsincludingathermostat,thelow-voltageoorsensorshouldbeplaced

thinsetorhotglue.SeeFigure7.
Thesensorwirecannotcrossanyheatingcableorleadwire.Itmustextendatleast6
inchesintotheheatedarea.Thesensoranditswireshouldbecovereddirectlywith
