Lockout Feature
Yourthermostathastheabilitytolockoutadjustmentbyotherusers.This
maybeusefulinpubliclocations.Onlytheon/offswitchandtheGFCItest
buttonwillthenoperate.
1.Pressthedownandupbuttonatthesametimeandholdfor1second.
LOCKwillshowonthedisplay.
2. Tocancelthislockout,thedownandupbuttonmustbepressedandheld
for1second.Thethermostatwillreturntothenormaloperatingmode.
Test the GFCI
ThereisaGFCI(GroundFaultCircuitInterrupter)insidethethermostat.It
isdesignedtohelpprotectpeoplefrompossibleelectricalshockiftheoor
warmingsystemhasbeendamaged.
TomakesuretheGFCIisoperating,testitafteritisinstalledandonceeach
month:
1.MakesurethethermostatisHEATING.Youmayneedtoincreasethe
setpointtemporarily.
2. PresstheGFCITestbuttononthesideofthethermostat.GFCI TRIP
shouldshowonthedisplayandaredlightwillshownexttotheGFCITest
button.Youshouldalsohearaclick,indicatingpowerhasbeenremoved
fromtheoorwarmingsystem.Ifanyoftheseindicatorsfail,turnoffthe
thermostatandreplaceit.Donotcontinuetouse.
3. ToresettheGFCI,slidetheOn/Offswitchoffandbackon.Ifthe
GFCIdoesnotreset,turnthethermostatoffandgotosection6

untilthenextscheduledprogramtime:
1.Pressthedownoruparrowbuttonandholdfor1secondtoadjustthe
setpointtemperature.
2. Wait5secondsandthethermostatwillreturntothenormaloperating
mode,savingyouradjustment.
3. Tocancelthistemporaryoverrideandreturntothenormal
scheduletemperature,presstheHOLD/RETURNbuttonbriey.
Hold a Selected Temperature
Youcanholdthecurrentsetpointtemperatureindenitely,
especiallyusefulwhenyouareonvacation.

Remote Control Override
IfyourthermostatwasinstalledwithRemoteControlinputfromahome
automationsystem(seesection2 “Installation”),thiswilloverridethe
thermostatwhentheremotecontrolsystemclosesitsoutputswitchorrelay.

Air Sensing and Regulator Modes
Yourthermostatisfactorysettooperatebasedontheoorsensor
temperature.Thisistherecommendedmethodtoproperlycontrolyouroor
warmingsystem.
However,itisalsopossibletoalsooperateyourthermostatineithertheair
sensingmodeorregulatormodetemporarilyiftheoorsensorwasdamaged
ornotinstalled.Anewoorsensorshouldbeinstalledtoenableoperation
inFloorSenseModeassoonaspossible.Thesemodesmustbeusedwith
cautiontoavoidoverheatingtheoor.
•AirSensingMode–Thismodeoperatesbyanairsensorinsidethe
thermostat.Ifyouroorsensorisconnected,youmustsetaFloorLimit
temperaturetoavoidoverheatingtheoorcoverings(seeFloor Limit
below).Note:the internal heating in the thermostat may affect the sensor
temperature.
•RegulatorMode–Inthismodetheuserselectstheamountoftimethe
oorwarmingsystemheatsduringa15-minuterepeatingcycle.Thereisno
temperaturesensinginthismode.(seesection5 “Operation”)
Ifyouwantittooperateintheairsensingmodeorregulatormode,youmay
changethisasfollows:
1.PresstheOPTIONSbuttonandholdfor1second.
2.PresstheOPTIONSbuttonagainuntilSENSshowsonthe

3.PressthedownorupbuttontotogglethistoAirorrEGu.
4.PresstheHOLD/RETURNbuttontoreturntothenormal

IfyousetyourthermostattooperateinAirSenseMode,thedisplaywillshow
theairtemperaturebutwillalsomonitortheoorsensorifitisconnected.
Toavoidpossiblyoverheatingyouroor,youmustsetaFloorLimittemperature
soitturnsoffthesystemiftheoorsensortemperatureexceedsthisFloor
