A NOTE ABOUT DOMETIC THERMOSTATS. Dometic currently has many styles of thermostats. Soon several styles will become obsolete as they pair their offerings down to just two styles. The first style is a square 3-4 button LCD thermostat used on systems with one air conditioner and a heater. Some versions also have the ability to run a heat pump or heat strip. The second style is a rectangular LCD CCC2 thermostat with an ambient temp sensor and has the ability to control up to 4 air conditioners, furnace, heat strips or heat pump.
