Does you original thermostat control the a/c and furnace?
The CTC Digital Thermostat model 43054 requires 24 volts. 24volts is for a residential unit
the original analog thermostat operates on 7.5 volts DC and wired different than CTC model
Had researched this when replacing my older a/c on another rv. had to install the upgrade kit. this includes the thermostat and the controller As Tunnel Vision posted. Dometic has installation manuals on line. with newer system uses only 3 wires instead of all 7 wires.
