WalTech UST 3.0 Smart RV Thermostat

WalTech Universal Smart Thermostat 3.0 (UST 3.0) is a smart RV thermostat that replaces your old wall thermostat and lets you control your RV's heating and cooling from your phone. It works with both the older R410A and the new R32 refrigerant, has built-in cellular and Wi-Fi, watches over your pet, and is a smart hub for up to 40 sensors.

Why RV owners choose WalTech

• Fits 95% of RV thermostats on the road. Coleman-Mach, Airxcel, Dometic, Furrion and GE (R410A). Old RV or brand new.
• R410A and R32. Ready for the new R32 air conditioners in 2025 and newer RVs.
• Built-in cellular and Wi-Fi. The only RV thermostat with built-in cellular. Patented. If campground Wi-Fi is weak, it switches to the strongest signal so you can still reach your RV (cellular needs the optional Cellular plan).
• Pet Mode. Get a phone alert when your RV gets too warm for your dog, then cool it down with one tap. Free over Wi-Fi.
• Smart Hub. Connect up to 40 Zigbee and Bluetooth sensors: WalTech water leak, door and window, pet motion, temperature and humidity, and air quality sensors, smart plugs and smart relays. Also works with Mopeka tank sensors for propane, water and diesel levels.
• Installs in 15 to 30 minutes. Numbered push-in terminals. Match each wire to its number.
• RV and home. Runs on 7.5V to 32V, AC or DC, so it also works with standard 24V home heating and cooling. No batteries.
