First-Time Setup

The first time your UST 3.0 powers on, it asks two questions. Answer them and you are done.

Before you start

Finish the wiring first. If you have not wired the thermostat yet, start with the wiring guide for your AC brand.

Turn the power back on. The WalTech logo shows while the thermostat starts up. The first time, it then opens the setup screens below. After that it always opens on Home.

Good to know: Setup takes about a minute. You only do it once.

Step 1: Your air conditioner

Tap your AC brand along the top, then tap the button that matches your system. Tapping a button takes you straight to step 2.

Careful: This screen has no Back button, and the choice cannot be changed later from Settings. If you pick the wrong one, use Erase Everything to run setup again. See Erase Everything.

Step 2: Your heaters

Now tell the thermostat what heat you have. There are three lines: Heater 1, Heater 2 and Heater 3 or B&O.

  1. Tap a line. Each tap moves to the next choice: Heat Pump, Heat Strip, Furnace, N/A. Keep tapping until it shows the right one.
  2. Do the same for the other two lines. Pick N/A for any heater you do not have.
  3. Tap Save & Finish.

All three lines must be filled in. If one still says Select, the screen asks you to choose all three heaters.

Good to know: What is B&O? It is a valve wire found on some home-style heat pump systems. It only matters on Coleman Single-Zone, Coleman Two-Stage and Home Thermostat. Most RVs pick N/A for Heater 3.
Tip: The order matters. Heater 1 comes on first. Heater 2 and 3 only help when the room stays too cold. A common pick is Heat Pump first, Furnace second.

All set

The screen says All set! and shows the AC you picked. Tap OK and you are on the Home screen.

The Home screen

If you have more than one AC, the Home screen shows a box for each zone on its own, once each AC reports its temperature. You do not set the number of zones.

What to do next

  1. Connect to Wi-Fi and link the WalTech app.
  2. Check for a software update.
  3. Learn the Home, dial and Control screens.
