Question:
It is stated that the Dometic 459516.701CO is replaced with a ACDOM150 without any modification to the thermostat or air delivery box. Does this unit have a built in control board as the above mentioned Dometic unit?

Thanks for reaching out Cliff,
Yes, the Advent Air # ACDOM150 is designed to replace your Dometic 459516.701C0 without requiring you to change your existing thermostat or air distribution box.
The control board that operates the system is in your current air distribution box, so the Advent rooftop unit does not need its own separate control board. The included adapter harness allows the new unit to communicate with your existing Dometic controls.
As long as your current Dometic system is using the original thermostat and ceiling assembly, the # ACDOM150 is designed to work with those components.
What style of RV do you own?

I own a 1994 Sundowner horse trailer with a small living quarters. I purchased this AC unit, along with the additional heat strip, and it works perfectly with the original Dometic ceiling assembly that I assume was the unit installed originally.
