SECTION 5
5.4.2 Install the TempZone™ Floor Heating Cable
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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.
4.Takenoteofthecable’shalfwaypointmarkingindicatedonthecable.Thismarkshouldmatchthehalfwaypoint
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
inbetweentheloopscreatedbythecableandheldinplacewithasmallamountof
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
thinsetorself-levelingunderlayment.
Thecoldleadwiresshouldbeplacedabovethesuboor,alongthesideoftheheated
areaatleast2inchesfromtheheatingwire.Securethecoldleadwireswithasuitable
tapeorhotgluebeforethethinsetorself-levelingunderlaymentisappliedoverthe
cables.
7.Useanohmmetercheckthecontinuity,insulationresistance,andresistancevaluesagainafterthecablehasbeen
installed.Comparethesepost-installationvalueswithpre-installationvaluestoensuretheyareconsistent.Recordpost-
installationvaluesonthewarrantycardinsection10.
AttachCircuitCheck™tocoldleadsatthistime.
