Dometic Penguin II Ceiling Assembly for Ducted - Pre-Installed Single Zone

What is the Dometic Penguin II ceiling assembly for ducted single zone installations?

The Penguin II ducted single zone ceiling assembly is the interior component that mates to a Dometic Penguin II rooftop air conditioner on a ducted RV. It directs conditioned air into the existing overhead duct network and houses the return air filter and control interface for a single thermostat zone. This pre-installed single zone configuration ships ready to wire to one wall thermostat, so you do not need a separate zone control board.

How do I confirm this ceiling assembly fits my Dometic Penguin II rooftop unit?

Check the model and serial tag on your existing rooftop unit before ordering. The Penguin II ducted ceiling assembly is built specifically for Penguin II low-profile rooftop air conditioners on a ducted ceiling opening (typically 14" x 14"). It is not interchangeable with FreshJet, Brisk, or Coleman ceiling assemblies. If you run a non-ducted system, look at the FreshJet 5 non-ducted ceiling assembly instead, and for ducted Coleman setups see the Coleman Power Saver HP ducted ceiling assembly.

Does the single zone version work with a thermostat I already have?

The pre-installed single zone configuration is wired to run one compatible Dometic wall thermostat controlling one rooftop unit. If you have a multi-zone or older analog thermostat, confirm compatibility with the Penguin II control board before installing. Reusing the wrong thermostat is the most common reason a new ceiling assembly will not communicate after install.

Can I pair this with a soft start to reduce generator and breaker stress?

Yes. A soft start lowers the compressor inrush current on the rooftop unit, which helps the AC run on smaller generators and reduces nuisance breaker trips. The ceiling assembly itself does not include one, but you can add a compatible kit from the Coleman RV air conditioner soft start collection when you service the rooftop unit.
