Verify that all features of the system work. See CCC 2 thermostat Operating Instruc- tions or User's Guide. Check fan speeds, cooling mode, heating mode, and furnace mode (if connected) operation. If features do not work, disconnect the 120 Vac and 12 Vdc power supplies and verify that all wiring is correct.

Temperature Differential Setting This system can be configured to operate using an ON//OFF differential of either 1 degree F or 2 de- gree F See (FIG. 45). 1. To set the differential, simultaneously press the PROGRAM button and the up button on the CCC 2 thermostat. “diF1” will appear in the display while the buttons are pressed. See (FIG. 45). To set the 2 degree differential, simul- taneously press the PROGRAM button and the down button. “diF2” will appear in the display while the buttons are pressed. FIG. 45 GENERAL INFORMATION A. Heat Gain The ability of this 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 conditioner. During extremely high outdoor tem- peratures, the heat gain of the vehicle may be reduced by: 1. Parking the RV in a shaded area 2. Using window shades (blinds and/or curtains) 3. Keeping windows and doors shut or minimizing usage 4. Avoiding the use of heat producing appliances Operation on High Fan/Cooling mode will give optimum or maximum efficiency 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, acces- sories 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. Condensation The manufacturer of this unit will not be responsible for damage caused by condensation 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, depend- ing 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. If your unit fails to operate or operates improperly, check the following before calling your service center.
