Backed by Micro-Air's 2-year limited warranty. Available at The RV Surplus.

⚠️ Critical Compatibility — Verify Before Ordering

The EasyTouch RV line has system-specific model numbers. Ordering the wrong model means the thermostat won't work with your RV's HVAC system.

This unit (357) is designed for older Dometic CCC systems only — identified by the Dometic CCC connector on the wiring harness (labeled "CCC," not "CCC2").

NOT compatible with:

• Dometic CCC2 — use EasyTouch 350 instead
• Dometic CT / SZLCD — use EasyTouch 351 instead

⭐ Control From Anywhere — WiFi + Bluetooth

Standout feature vs traditional RV thermostats: full remote monitoring and control from your smartphone. Meaningful benefits:

• WiFi Connected — control your RV's climate from anywhere with an internet connection (home, work, across the country)
• Bluetooth Backup — wireless local control within range of your RV, even without internet
• Temperature Alerts — push notifications when temperatures go too high or too low; critical for protecting pets, preventing water line freezing in cold weather, avoiding heat damage to electronics/perishables, or monitoring your RV in storage
• No monthly fees, no subscriptions — the free Micro-Air EasyTouch RV app works with your existing internet (RV park WiFi, mobile hotspot, onboard router, Starlink)

⭐ Programmable Scheduling

Standout convenience vs basic on/off thermostats: set automatic temperature changes based on time of day. Program your A/C to cool down before you wake up, warm up before you return from a hike, or maintain different temperatures throughout the day. The schedule works even without WiFi once programmed — locally stored in the thermostat.

⭐ Auto-Detection & Broad HVAC Compatibility

Standout install benefit: the EasyTouch automatically detects what heating and cooling sources are available in your system and displays only the relevant options. Handles:

• Air conditioning (compressor cooling)
• Heat pump operation
• Electric heat strip
• Propane furnace
• Combinations of the above (multi-zone with proper wiring)

Whether you have single-source or multi-source climate control, the thermostat adapts to your setup automatically during initial configuration.

⭐ 3.5" Color Touchscreen

Standout display vs legacy Dometic CCC monochrome LCD thermostats:

• Large, easy-to-read display (3" H × 3.9" W screen area)
• Touchscreen controls — no fiddly buttons
• Color status indicators for clarity at a glance

⭐ Additional Smart Features

• Over-the-air firmware updates — free updates via WiFi keep your thermostat current
• Settings backup — never lose your preferences during power loss or reset
• Temperature sensor calibration — fine-tune accuracy to match your preferred reference
• Auto fan changeover — intelligent fan control between heating and cooling modes

Prefer Black Instead of White?

Same EasyTouch RV 357 is available in a black finish: ASY-357-X01 — choose based on your RV's existing thermostat trim. Please reach out if you'd prefer this unit and your order can be swapped to a black one.

Easy DIY Installation (Most Cases)

The EasyTouch is designed for DIY installation on most Dometic CCC systems:

1. Remove old thermostat (pop off cover, remove mounting screws)
2. Document existing wiring (photograph before disconnecting)
3. Connect wires using the included harness/connectors
4. Mount new thermostat using included hardware
5. Power up and configure via on-screen setup
6. Download the free app and pair via Bluetooth, then add WiFi
