Replacement AC Units for Tiffin Allegro Bus with Three Units and Aqua Hot

Published 01/28/2022

Question:

I have three Dometic Duo Therm air conditioners on my 2006 42.5foot Tiffin Allegro Bus that I need to replace. The RV has an Aqua Hot heating system so I would need to replace the air conditioners and thermostat with something that would be compatible with both systems. I would like to include either heat pumps or heat strips with the air conditioners. The system has 3 zones. I plan to do the install myself if possible. Let me know if you need more information. Thanks in advance for your help!

Since the Aqua Hot system you have uses a thermostat that has fluid that runs to it there isn't going to be an AC unit thermostat out there that would tie into that so that you'd only need a single thermostat.

Furrion has 2 zone AC units like with the part # FR67FJ but for a third unit you'd need a single with it's own controller like # FR55PV.
