Mode of Operation
Thethermostatisaprogrammable,manualorautochangeover,upto3-stageheat(dependingonyourmodel)andupto
2-stagecool(dependingonyourmodel)thermostat.Itfunctionswithairconditioning,heatpumps,gas,oil,orelectricheat
systems.Somethermostatsaredualfuelcompatibleandanoutdoorsensorcanbeusedtomonitortheambienttemperature.A
secondremotesensormaybeusedtomonitorthetemperatureinanotherarea.Thethermostatactivatestheheatingappliance
whentheroomtemperatureisbelowthesetheattemperature(bythedifferentialtemperature).Whenthecallforheathasbeen
satised,theoutputsareturnedoff.Withheatpumps,thethermostatwillnotletthecompressorcomeonfor4minutesafterit
turnsofftoprotectyourcompressor.
Whentheroomtemperatureisgreaterthanthesetcooltemperature(bythedifferentialtemperature),thecoolingdeviceis
activated.Whenthecallforcoolinghasbeensatised,theoutputsareturnedoff.Thethermostatwillnotletthecompressor
comeonfor4minutesafteritturnsofftoprotectyourcompressor.
Theprogramschedulecanbeoverriddenbychangingthesettemperature( or ).Thisputsthethermostatintoa
temporaryhold.Itwillautomaticallyreturntotheprogramscheduleatthenextprogramscheduletransition.Toremovethe
temporaryholdbeforethenextscheduletransition,press icontwice.
ThethermostatisalsoWi-Ficompatible.Afteryouconnectyourthermostattoyourwirelessnetwork,youcanmonitorand
controlyourthermostatusingtheapp(availableformostdevices)oracomputerconnectedtotheinternet.
