Initial setup instructions. Operating the thermostat. Main screen. Operational modes. Auto gas changeover. Local weather and local time.
• Page 3: EasyTouch RV 356 model thermostats were designed to directly replace certain 12-volt Coleman, Airxcel, RVComfort, TrueAir, and ComfortGuard systems. EasyTouch RV 356 can be purchased in two colors. Obsolete thermostats are no longer sold, but their operations and build quality were identical to the latest thermostats. Tables list the known OEM model numbers that can be used with EasyTouch RV 356. A 4-to-3 wire harness is provided with EasyTouch RV 356 that may or may not be needed. Refer to the section Wiring the Thermostat for how and when to use the harness. The “G (as) C (hangeover) Ver (sion)” columns are referenced in the section Auto Gas Changeover Type of the Initial Setup Instructions. Thermostat model numbers can be found in your original user’s manual and on the back side of the thermostat. Note that a “*” character means any character in that position is a match. Please contact Micro-Air to verify if your thermostat model is correct for your application.
• Page 4: EasyTouch RV model 356 is shipped with several items including a thermostat, quick-start guide, and various adapters. The quick start guide helps with quick installation and setup of the thermostat. The mounting bracket and adapters are for installation, with screw hole covers for previous thermostat holes. For installation, it is recommended to remove both AC and DC power from the system. The original thermostats have a front cover that pops off, revealing mounting screws. Inspect the wiring after removing the old thermostat to understand the installation. Some RV builders use proper plugs for thermostat connections, while others may use direct wiring. The installation guide provides detailed directions that may not be included in the quick-start guide. Safety precautions are essential to prevent electrical discharge during installation. Different RV systems may have varying plug configurations or direct wiring methods.
• Page 5: Wiring the thermostat is crucial for proper installation. Ensure that you can see where the thermostat wires meet with the wall wires, as they are typically different colors. Use Table 4 to record what color wires meet. If using Molex plugs, simply plug in all the mating connectors. Not all installations will use all plugs; ensure every original plug has an EasyTouch match. If the Molex plug from the wall has a 3-pin plug, use the provided 4-to-3 pin adapter harness. If you have a 4-wire plug coming from the wall, you will not need the adapter harness. For non-standard Molex plugs, follow the Direct-Wired section directions to complete the wiring. The original thermostat will have wires connected to the RV manufacturer’s wiring harness. Write in the RV wiring harness colors in Table 4 before making connections.

• Page 7: EasyTouch RV 356 Micro-Air provides a 9-pin harness to interface between EasyTouch and the RV manufacturer’s wires. You will have to source or reuse electrical connectors to make these connections. EasyTouch will also have a pre-wired 2-pin connector and a pre-wired 4-pin connector attached to the back. Connect the provided 4-to-3 pin adapter harness to EasyTouch. When you know where each wire goes you should begin cutting wires. You must check your wiring to determine what additional hardware your system may have. Inspect your OEM thermostat wires for either two gray wires or a green wire. If your system is Direct-Wired, use Table 4 to connect your gray wires to the gray wires of the Micro-Air 9-pin harness. Restore DC power. The thermostat screen should light up and boot into the main menus. Restore AC power so that your appliances can run again.
• Page 8: Mounting the thermostat involves several steps. Locate the mounting bracket horizontally across the hole with the smaller diameter of the mounting button against the wall. Remove the mounting tab before mounting the thermostat on the wall. Screw in one screw and level the buttons so the display will be straight when installed. Screw into the smaller hole of the two buttons. Screw in the second screw and make sure the buttons are flat and level. The larger diameter button has some play to make these adjustments easier. Align the buttons with the holes in the back of the display. Press the display against the wall and gently slide the display down to lock it in place. ©2023 Micro-Air LLC, Revision 2.1
• Page 9: EasyTouch RV 356 Initial setup instructions EasyTouch RV 356 is meant to replace a few different OEM thermostats and must be configured for your system prior to using it.

Set the Operational Mode button to Furnace Only or Aqua Only and the desired Fan Speed. Furnace Only Mode Cycle Operation None Inside returns 1° above setpoint, Furnace Stage #1 Off. Table 7 operation may be different based on the Gap settings. All heat modes are subject to Auto Gas Changeover Operation when enabled. Auto Modes These modes will automatically switch between heating and cooling cycles as needed. Auto modes will have their own dual set-points that are separate heating and cooling set-points. No heating or cooling cycles will occur when the inside temperature is between the setpoints.
• Page 13: EasyTouch RV 356 Auto Gas Changeover Auto Gas Changeover operation mirrors the OEM thermostat’s operation for additional stages of heat when the thermostat determines more are needed. The three escalating stages are shown in Table 8. Stage 2 heating is available in every system. The below tables are based on “Version A” type of Auto Gas Changeover, which is the default selection. The temperature and runtime values can also be adjusted from the same setup screens where “Type” is set. Table 9 shows how Auto Gas Changeover affects the Heat Pump operational modes when enabled. Table 10 shows how Auto Gas Changeover affects the Furnace operational modes when enabled. Note: Table 9 operation may be different based on the Gap and/or Setup settings. Note: Table 10 operation may be different based on the Gap and/or Setup settings.
• Page 14: EasyTouch RV 356 Local weather is displayed on the main screen whenever Wi-Fi and internet is available. A valid location and an internet connection on the thermostat are required to retrieve weather data. Local time data also requires valid location data. Location is preserved through power losses or device restarts. New weather data is retrieved when there is any screen press or when a connection from a smart device is made. Time is pulled in when a Bluetooth or Wi-Fi connection is made from the app. Tapping the weather icon area will change to the weather screen that will show the last valid weather data. Some messages may be displayed on the main screen as shown in the Status Message section. The room sensor inside EasyTouch RV has failed open/disconnected or shorted. The freeze sensor is open to say that the indoor coil has frozen up under cooling operation and should be serviced. When 120 Volts AC is removed, the sensor no longer operates as expected and reads open. This means that the two-hour timer of the Auto Gas Changeover logic is active.
