B. Zone Control
ZonesareestablishedatthetimeoftheinstallationofyourDometicCCC2thermo-
stat.Azoneisanareaofcooling/heatingwhichiscontrolledindependentlybythe
CCC2thermostat.TheCCC2thermostatallowsforfourzones(AirConditioner/
Heat Pump) to be set up and run independent of each other. If you have one air
conditioner/heatpumpinstalled,youwillhaveonezone.IfyourRVhasmorethan
onecooling/heatingsystem,youmayhavetwo,three,orfourzones.
YourCCC2thermostatwilloperatecoolingandheatingappliancesthatyourvehicle
manufacturerhasdesignedtocoolorheatspecicareas(zones)ofyourRV.The
CCC2thermostatwilladviseyouofthenumberofzonesinyourRV.Thezonesare
displayed“1”,“2”,“3”,or“4”intheLCDreadout.Seesection,“D.QuickReference
To LCD Icons” on page (5).
Intheevent your vehiclehasmultiple zonesdesigned,you have thefreedomof
selectingdifferentmodesofoperationsforeachzone.Tochangefromonezoneto
another, press the ZONE button on the CCC 2 thermostat. Each time the button is
pressedandreleasedtheindicatorwillchangethezonedatadisplayed.Whenthe
zoneshavebeenprogrammed,thezonesinoperationwillbedisplayed.Toprogram
eachzone,simplyrepeattheprogrammingstepsshownundermainheading,“Pro-
gramming&Operations”onpage(6).
C. Program “1” & “2”
TheDometicCCC2thermostatcanstoretwooperatingprograms.Eachprogram
canbesetonindividualzoneswithdifferentmodeandtimesettingsforeachzone.
For each event the user can program the operating mode, fan speed, temperature
set-point, and the time of day for the event.
1. Selectthezonetobeprogrammed.
2. Selectprogram“1”bypressingthePROGRAMbutton.“PROG1”iconwillblink
ontheLCDdisplay.
3. Press the CLOCK button to set the time of day for program to start.
4. Press the MODEbuttontoselectthemodeofoperation.
5. Press the FANbuttontoselectthefanspeed.
6. Press the PROGRAMbuttontosavethe“PROG1”settings.LCDwillnowdis-
play“PROG2”.
To set program “2”, repeat steps (3) through (5).
7. Press the PROGRAM button again to save program(s) in memory.
Dependingonthetimeofday,program“1”or“2”willbeginimmediately.
Forinstance,ifprogram“1”issettobeginat10:00AMandthetimeofday
is10:30AM,program“1”willbeginimmediately.Ontheotherhand,ifpro-
gram“1”issetto10:00AMandprogram“2”issettobeginat6:00PMand
thetimeofdayis7:00PM,program“2”willbeginimmediately.

14
Whenprogram“1”or“2”isoperating,the“PROG1”or“PROG2”iconwillbedis-
playedintheLCD.Thezonewillcontinuetooperateintheprogrammedsettinguntil
theprogramismanuallycancelled.
Tocanceltheprogramoperation,pressandholdthePROGRAM button for 3 sec-

GENERAL INFORMATION
A. Reduce Heat Gain
Theabilityoftheairconditionertomaintainthedesiredinsidetemperaturedepends
ontheheatgainoftheRV.Somepreventativemeasurestakenbytheoccupants
oftheRVcanreducetheheatgainandimprovetheperformanceoftheaircondi-
tioner.Duringextremelyhighoutdoortemperatures,theheatgainoftheRVmay
bereducedby:
● ParkingtheRVinashadedarea.
● Usingwindowshades(blindsand/orcurtains).
● Keepingwindowsanddoorsshutorminimizingusage.
● Avoidingtheuseofheatproducingappliances.
OperationonHighFan/Coolingmodewillgiveoptimumormaximumefciencyin
high humidity or high outside temperatures.
Startingtheairconditionerearlyinthemorningandgivingita“headstart”onthe
expectedhighoutdoorambientwillgreatlyimproveitsabilitytomaintainthedesired
indoor temperature.
Foramorepermanentsolutiontohighheatgain,accessorieslikeDometicoutdoor
patioandwindowawningswillreduceheatgainbyremovingthedirectsun.They
alsoaddaniceareatoenjoycompanyduringthecooloftheevening.
B. Disclaimer
Themanufacturerofthisunitwillnotberesponsible fordamagecaused bycon-
densationformingonceilings,windows,orothersurfaces.Aircontainswatervapor
whichcondenseswhentemperatureofasurfaceisbelowDewpoint.Duringnormal
operation this unit is designed to remove a certain amount of moisture from the air,
dependingonthesizeofthespacebeingconditioned.Keepingdoorsandwindows
closed when this air conditioner is in operation will greatly reduce the chance of
condensation forming on interior surfaces.

MAINTENANCE
A. Air Filter
Periodic cleaning or replacement of the air conditioner/heat pump air lters
is required. NEVERruntheairconditionerwithouttheairlterinplace.This
mayplugtheunitevaporatorcoilwithdirtandmaysubstantiallydegradethe
performance of the unit over time.
Whenasystemfanruntimeexceeds1000hourstheltericonisdisplayedinthe
LCD. (See section, “D. Quick Reference To LCD Icons” on page (5).) When this
occurswashthelterwithsoapandwarmwater.Letdryandreinstall.
To reset the fan run time and clear the lter icon, hold the INSIDE TEMP and
°F / °Cbuttonsfor3seconds.Thiswillclearthefanruntimeforthecurrentzone
selected.
B. Dometic CCC 2 Thermostat
DO NOTspraywaterdirectlyontheCCC2thermostat.DO NOTusesolvents
forcleaning.
CleantheCCC2thermostatwithamoistsoftcloth.
SERVICE
Intheunlikelyeventtheunitfailstooperateoroperatesimproperly,checkthefol-
lowingbeforecallingyourservicecenter.
● IfRVisconnectedtoamotorgenerator,makesurethemotorgeneratorisrun-
ningandproducingpower.
● IfRVisconnectedtoapowersupplybyalandline,makesurethelineissized
properlytorunairconditionerloadanditispluggedintothepowersupply.
● Checkthe120Vacfuseorcircuitbreakertoseeifitisopen.Makesurefuseis
not burnt, or circuit breaker is ”ON” and not activated.
● Checkthe12Vdcfuseorcircuitbreakertoseeifitisopen.Makesurefuseisnot
burnt, or circuit breaker is ”ON” and not activated.
● Aftertheabovechecks,callyourlocalservicecenterforfurtherhelp.Thisunit
mustbeservicedbyqualiedservicepersonnelonly.
Whencallingforservice,alwaysgivethefollowing:
● UnitModelNumberandSerialNumberfoundonIdenticationLabellocatedon
