If a telephone extension cable is used it will not light up the thermostat. Dometic does not provide the cable for the Comfort Control system. The cable is provided at time of install. A cable tester available 30727.007. To check DC voltage at the thermostat , remove from mounting bracket.
Roof Top Heat Pump When the thermostat calls for that function and the Circuit is completed the light will illuminate. This is an energized circuit. Shock can occur if not tested properly. Testing is to be done by a qualified service technician. To verify circuits are being completed by the Analog con- trol board/box, you would first disconnect the 6-pin plug connector from the Analog Control Box.

4.10 Capacitors Duo-Therm Air Conditioners and Heat Pumps use three different capacitors: 1) compressor run capacitor 2) com- pressor start capacitor and 3) fan/blower capacitor. On some units the compressor run and fan/blower capacitor are in the same case. This is an energized circuit. Shock can occur if not tested properly.

4.15 Comfort Control Temperature Sensors 4.13 Ducted Heat Strip The comfort control uses three types of remote tempera- ture sensors. Remote room sensor used when multiple zones are used. Cold (FREEZE) Control sensor used to stop the inside coil from freezing. Ambient sensor used on Heat Pumps to tell the control system it is a heat pump and communi cate the outside temperature.

SECTION 7 Proper Thermostat Location THE THERMOSTAT LOCATION IS VERy IMPORTANT FOR BALANCED TEMPERATURE CONTROL IN A RV. Today’s interior design of the RV has become both cos- metically more appealing and more efficient in its use of storage space. These improvements have generated complex interior space requirements which, in turn, have caused many RV’s to become a maze for heating and air conditioning circulation.
