Question:

I currently have a 15000 btu dometic ducted ac with wall mount thermostat that controls both ac and propane furnace. I was looking at your furrion 18000 cubes and see two options ones with remotes and others with wall thermostats. If I went with the remote option I understand the ac unit would no longer be controlled by the factory wall domestic brand thermostat but would I still have control of my furnace using the original wall thermostat? I also see you have an option for wall thermostats. Could I replace my domestic wall thermostat head with a furrion brand thermostat using the existing coach wiring and have it operate both ac and furnace?

Yes, you can Kyle! To operate your furnace and replace your Dometic ducted AC unit you'll need the Furrion Chill Cube RV AC w/ Air Distribution Box, Thermostat item # fr49td.

What type of RV do you have?

Thank you Jerred. I have a 2014 Palomino Columbus 320rs. Essentially what I’d like to do is replace the ac ducted unit I have and still be able to use my original domestic wall thermostat to control the new ac and still maintain my original furnace function. I found that there appears to be a wiring conversion kit/harness that may allow for this C-FACR15SA-A01. So what I gather is I should be able to buy a new Furrion Cube 18000 ducted version that allows me to reuse my original distribution box and controls as long as I also purchase the conversion wiring kit/harness. Feel free to correct me if I’m off base. If you could kindly confirm which Furrion cube model would do this I would greatly appreciate it.

@Kyle You're welcome! Sorry but nothing works with the new Furrion Chill Cube item # fr49td including the Coleman RV Air Conditioner Adapter Wiring Kit item # C-FACR15SA-A01. It's a brand new system and will not be backwards compatible with any older Furrion components or other brands.

So if I buy the fr49td just confirming I would not need anything else correct? Ac would be controlled with remote while I could still control my furnace with the old dometic thermostat.

@Kyle Yes, but also a little bit of no. You won't need your old Dometic thermostat anymore. Everything will be controlled by the one included with the Furrion Chill Cube RV AC w/ Air Distribution Box, Thermostat item # fr49td. The problem with the old thermostat is it's powered by the AC so your Dometic one will be useless.
