Dometic ADB 3314850.000 Compatible Thermostats

What thermostats are compatible with the Dometic ADB 3314850.000?

This collection lists thermostats verified as direct replacements or upgrades for the Dometic ADB 3314850.000 analog control. Both options work with single-zone Dometic Brisk Air and Penguin systems that originally shipped with the 3314850.000 control box. Confirm your existing wiring configuration (cool only vs. heat/cool, ducted vs. non-ducted) before ordering.

Will these thermostats work with a heat pump or heat strip setup?

The 3314850.000 control box supports cool-only, heat strip, and heat pump configurations depending on how it was wired at the factory. Match the replacement thermostat to your current setup. If you have a heat pump ceiling assembly, see our FreshJet 5 heat pump ceiling assembly or Coleman Power Saver HP ducted ceiling assembly for matched air distribution parts.

How difficult is it to install a replacement thermostat?

Most owners can complete the swap in under 30 minutes with a Phillips screwdriver and a label maker or masking tape for the existing wires. Disconnect shore power and the battery before pulling the old thermostat, label each lead by terminal letter, and transfer them one at a time to the new unit. A reduced startup load also helps protect the new control circuit, see our Coleman RV air conditioner soft start kits.

How do I confirm I have the 3314850.000 control box?

The part number is printed on a white label on the control box itself, mounted inside the return air opening on the ceiling assembly. Drop the air filter grille and look for the 3314850.000 stamp. If the label is missing or unreadable, text or call our team at 817-984-1852 with a photo of the box and your AC model number, and we will confirm the correct thermostat for your system.
