Timers—Thereareseveraltimerswhichinuencethe
thermostat’soperationthatarelistedbelow.Ifanyofthe
timersispreventingtheequipmentfromturningon,the
“on”iconwillash.
Five-Minute Compressor Timeguard — This timer
preventstheY1outputfromturningonunlessithasbeen
offfor5minutes.(Option07settoOF)
Afterapowercycle,arandomizeddelaywillbeadded
toendofthetimeguardtimertopreventmultipleunits
fromhittingthepowergridallatthesametime.The
randomizationtimerwillbebetweenzeroandve
minutes.Ifademandexists,compressoroutputswill
energizebetween5and10minutesafterthepower
cycle.Itcanbedefeatedbysimultaneouslypressingthe
fanandupkeys.
Minimum On Timer —Oncetheequipmenthasbeen
turnedon,itmustremainonfor3minutes.Achangein
modeorsetpointwillcancelthistimer.
Cycle Timer—Thenumberofequipmentcyclesperhour
isdeterminedbycongurationOption16.Basedonthe
selectionof4,6or8cyclesperhour,thistimerissetto
15,10or8minutes.Thismuchtimemustelapsefromthe
startofonecyclebeforeanothercyclecanstart,imposing
thecyclesperhourlimits.Itcanbedefeatedforonecycle
bysimultaneouslypressingthefanandupkeys.
TROUBLESHOOTING
Therearethreesystemerrormessagesthatmayappear
onthethermostatscreenindicatingaproblemwith
thethermostat’soperation.Seetextbelowforpossible
system error messages and their meaning.
Space Temperature Sensor Failure — If the room
temperaturesensorfails,thetemperaturedisplaywill
show“--”(twodashes).Ifthespacetemperatureis
theaverageofboththelocalandremotesensors(as
conguredinOption5),andoneofthesensorsfails,the
thermostatprovidescontroltothevalidsensoronly.The
displaywillalternateevery10secondsbetween“--”for
the invalid sensor and the reading from the valid sensor.
Memory Failure —Ifthereisaninternalmemoryfailure,
thetemperaturedisplaywillshow“E4,”thethermostat
needstobereplaced.
