andaoorsensortoregulatetheactualtemperatureoftheoor
•Non-GFCIcircuitbreaker
Inmostinstallations,aClass-AGFCIisrequiredbynationalandlocalcodesforprotectionagainstgroundleakagecurrents.
AClass-AGFCIisincludedwiththeSmartstat™andEasystat™thermostats.IfnotusingaWarmlyYoursthermostat,a
Class-AGFCIthermostatorcircuitbreakermaybeneeded.
TheTempZone™FloorHeatingCableshouldbeconnectedtoanon-GFCIcircuitbreakerforcompletedisconnectiononall
poleswithminimum0.12inchdisconnectiondistance.
Thethermostatshouldbeinstalledinadouble-gangboxwithasingle-gangmudringushwiththewallataheightof
approximately5feetoreyelevelforeasyaccessandoperation.TheoorsensorcableandtheTempZone™FloorHeating
CablecoldleadsshallberoutedtothethermostatinseparateULListedconduitsifconduitisrequiredbylocalandnational
electriccodes.
Iftheoorheatingcableloadexceedsthe15-ampthermostatpowerrating,consultWarmlyYoursforinformationon
