Matching RVAltCtrl to your RV model tells it how to talk to your RV's systems, lights, climate, tanks, and everything else the device controls. This is a one-time step: once it's set, you won't need to come back to this page again.
RV Model Not Set Up
Until you've picked a model, RVAltCtrl's Home page shows a reminder that this step isn't done yet, a card titled RV Model Not Set Up, with a shortcut button straight to the page where you set it.
Tap Go to RV Model to jump there directly, or get to the same page from Settings → RV Model.
Selecting your RV model
On the RV Model page, tap the Select your RV model dropdown.
That opens a list of every RV model RVAltCtrl supports. Pick the one that matches yours.
For CZone-equipped RVs, choose the CZone option for your model and let RVAltCtrl auto-detect the rest of the configuration, that's the best choice for almost everyone with a CZone system. There are further dropdowns below the model selector that auto-detect fills in for you automatically; you can also populate them by hand if you ever need to override what auto-detect finds.
Once you've made your selections, press Save to Device. RVAltCtrl will automatically reboot, a quick process that takes about 10 seconds, to apply your RV model. That's it, this page won't have to be used again.
