MICRO-AIR 357 Black EasyTouch RV Thermostat Replacement

Our review of the MICRO-AIR EasyTouch 357 Black finds it is a practical, feature-rich replacement thermostat for RV owners who want app control and an upgraded interface. The single biggest reason to pick this unit is its combination of a large colored touch screen and wireless access - you can program temperature schedules on the device or use WiFi and Bluetooth to turn the RV climate on before you arrive. Installation is straightforward for systems that match the 5-button Dometic form factor, and the unit detects furnaces, heat strips, and cooling automatically for cleaner setup.

Key Features

• Large touch screen: The colored 4 in x 3.05 in display gives one-touch temperature adjustment and is easy to read even in low light.
• Wireless app access: Built-in WiFi and Bluetooth let you control heating and cooling from a smartphone without monthly subscription fees.
• Programmable schedules: The EasyTouch supports multi-setting daily programming so you can automate comfort across the week.
• Auto system detection: The thermostat recognizes furnaces, heat strips, and air conditioning sources to simplify configuration.
• Direct replacement fit: The 357 Black is designed to replace 5-button Dometic models so it fits common RV control cutouts and wiring patterns.

Who It's For

This thermostat is best for RV owners who want a clear, modern interface and the convenience of remote climate control; families or frequent travelers who pre-cool or pre-heat their cabin will especially appreciate the WiFi/Bluetooth control. It also suits users replacing older 5-button Dometic thermostats who need a compatible, drop-in style thermostat with added programmability.

People who lack WiFi at their parking location or who need a thermostat for a non-standard HVAC control layout should double-check compatibility before buying. Professional installers or owners of custom HVAC systems may prefer to verify wiring and feature support against their specific controller models.
