Thermostat Needed to Install Dometic FreshJet 3 AC Unit
Updated 10/27/2025 | Published 03/12/2025 >
Question:
I am considering a Dometic Freshjet 3 as a replacement for an old 2006? Duo Therm 630516.331 unit that has the control box built into hardwired the rooftop unit. Therefore, Ill need a new control box to operate the new AC as well as the existing furnace. Is the DMC83ZR what i need?

Hey Fraser, yes the Dometic thermostat part # DMC83ZR that you referenced is correct for you to use when adding the Dometic Freshjet 3 part # DMC49ZR. This thermostat had furnace controls as well.
