Question:
Im replacing a Carrier Air V and have a couple of questions about this ac. Can you tell me the difference between the FR49TD and the FR99TD? I dont have a wall thermostat currently and was planning to use the wall thermostat from the FR49TD to control only my furnace. Will this configuration work? Is there anything else I need in order to replace my old ac?

Keegan, I completely understand wanting to get this right before ordering because replacing an AC is one thing, but finding out afterward that the thermostat will not play nicely with your furnace is a headache nobody wants to deal with.
The main difference between the two models is that the Furrion Chill Cube part # FR49TD includes the wall thermostat and remote, while the # FR99TD includes the remote but does not include the wall thermostat. Other than that, they are essentially the same 18,000 Btu ducted Chill Cube system.
As for using the FR49TD thermostat to control your existing furnace, that is where things get a little tricky. Some customers have successfully wired the Furrion thermostat to their furnace, but compatibility can be hit or miss depending on the furnace and control wiring. Furrion does provide wiring diagrams for furnace integration, but I cannot confidently guarantee it will work with every older furnace setup.
Honestly, if your current furnace thermostat is working well, I would lean toward keeping it in place and using the FR99TD to control the air conditioner with the included remote. That approach tends to be the simplest and avoids spending time troubleshooting furnace compatibility issues. The good news is that either Chill Cube system is a major upgrade over the older Furrion when it comes to cooling performance, efficiency, and noise level.
One other thing to keep in mind is that both the FR49TD and FR99TD are ducted air conditioning systems, so your RV will need to have existing ceiling ductwork for either of those options to work properly. If your RV is a non ducted setup, then you would want to look at the Furrion Chill Cube part # FR59TD instead.

I definitely spend the majority of my camping time in humid coastal areas. With respect to the furnace thermostat, the carrier air v relied on the remote and the in ceiling controller for controlling the ac and furnace. I do not usually use the furnace since I generally camp in the warmer months, so controlling it is lower priority. Thanks for the information!
