Congratulations! Your recreational vehicle manufacturer has equipped your RV with
the most advanced RV thermostat. Your Dometic Comfort Control Center 2 thermo-
stat (hereinafter referred to as the CCC 2 thermostat) has been designed for ease of
operation and for many years of reliable service.
Features
• Liquid Crystal Display
• 2 operation programs
• Outdoor temperature sensing (select models)
• Constant time of day display
• Remote Sensor (Precise comfort control within 1º F. of set-point)
• Display reminder lets you know when to service or replace lters
• Up to 4 independent zones
To help familiarize yourself with the operation of the CCC 2 thermostat, review the
following diagrams and accompanying text that explain the functional characteristics
of this system.
Your CCC 2 thermostat is equipped with a liquid crystal display (LCD) that identies
the mode of operation (OFF, Cool, Heat Pump, Fan, Heat Strip, Auto, & Furnace or
Aqua), temperature set-point, zone identication (1, 2, 3, 4), fan speed (Auto, Low,
Med, High), program 1 and 2, inside temperature, outside temperature, clock, ºF/ºC,
compressor delay, lter maintenance, and dehumidify operation with humidity set
point. The modes of operation viewed in the LCD will vary depending on the system
installed in your RV.
System Conguration & Initialization
The installer of your system will set the required system DIP switches to the ON
position. In order for the CCC 2 thermostat to recognize the system zones, type of
units installed and their options, a system reset must be done. Once the system is
completely installed, do a system reset.
• Make sure the CCC 2 thermostat is in the OFF condition. See page 3, Quick
reference to control buttons.
• Simultaneously press and hold the MODE and ZONE buttons. See page 3,
Quick reference to control buttons.
• The LCD will display “IniT” and all available zones.
• Release the MODE and ZONE buttons.
• Press the ON/OFF button to exit system set up.
The furnace ON/OFF temperature differential should be set at this time. See “Pro-
gramming & Operations” on page 7 for further information on furnace mode dif-
ferential setting.
Any time a system reset occurs, the factory default settings are restored. See “Fac-
tory Preset Settings” on page 3.
In the unlikely event of CCC 2 system memory loss or dip switch setting change,
the CCC 2 thermostat will require a system reset. Refer to page 11 for system reset
procedure.
