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 identifies the mode of operation (OFF, Cool, Heat Pump, Fan, Heat Strip,Auto, & Furnaceor Aqua), temperature set-point, zone identification (“1”, “2”, “3”, “4”), fan speed(“Auto,” “Low,” “Med,” “High”), program “1” and“2”, inside temperature, clock,°F / °C, compressor delay, and filter maintenance. The modes of operation viewed in the LCD will vary depending on the system installed in your RV.

B. System Configuration & 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.
