The EasyTouch 356 model thermostats were designed to directly replace certain 12-volt Coleman™, Airxcel™, RVComfort™, TrueAir™, and ComfortGuard™ single zone, single/dual-stage compressor, single/dual-stage heater systems. These are typically “basement units” in Winnebago or Alfa brand recreational vehicles. Please use section EasyTouch RV 356 Models and Compatible Replacements to make sure that this model is right for you.
Removing the Old Thermostat The original thermostats have a front cover that pops off. Behind the cover there are 2-4 mounting screws that must be removed to free the back plate. Once the thermostat is removed, pull out some of the wire from the wall to inspect how it was installed. Some RV builders will use the proper plugs recommended by the original thermostat manufacturer, which is also how EasyTouch RV is designed. This means you can simply unplug the thermostat and proceed to the next section.

Micro-Air provides a 9-pin harness that will be used to interface between EasyTouch and the RV manufacturer’s wires. One side plugs into EasyTouch RV while the other wire end side is used to make your new wire connections. 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.
Step 3: Screw in second screw making sure the two buttons remain level. Mounting the Thermostat Step 1: Locate the mounting buttons horizontally across the hole with the smaller diameter against the wall. Step 4: Remove mounting tab before mounting on the wall. Step 2: Screw in one screw and level the buttons so the display will be straight when installed. Step 5: Aligning the buttons with the holes in the back of the display.
Initial Setup Instructions Configure your Available Outputs EasyTouch RV 356 is meant to replace a few different OEM thermostats and so must be configured for your system prior to using it. Tap the Settings button on the main screen, then navigate to the Switches button and tap it. Tap the heat pump button to enable or disable it based on what is installed in your system. A red circle with a line through it over the button indicates disabled. Cool and gas furnace are always enabled.
Operating the Thermostat Main Screen This screen is where most time is spent using the thermostat. This screen allows you to set and monitor the desired operation of the thermostat and is shown in Figure 1. (1) Inside temperature This is the temperature reading for the space that the thermostat is trying to temper, determined by a local sensor. “Inside” means it is using a sensor inside the thermostat.
(6) System Power Use the power button to turn the system on or off. Button is red for off and green for on. Power (7) Operational Mode Pressing the mode button changes the current operating mode depending on what is available in your system. All possible modes are listed below. See the Operational Modes section for more details.
Operational Modes All modes operate the overhead fan and/or a heating or cooling cycle based on the current heating or cooling setpoint, relative to the inside temperature. Fans and Fan Only Mode This mode lets the fan to operate based on the chosen (8) Fan Speed. This will circulate the air without operating any heating or cooling cycles. Fan Only Mode Fan Speed Cool Only Mode This mode only runs a cool cycle to maintain the cooling set-point in the space.
Environment (°F) Cycle Operation Auto Fan Operation Inside ≥ Setpoint Inside 1° Or More Below Setpoint Inside Returns 1° Above Setpoint None Furnace Stage #1 On Furnace Stage #1 Off Off Table 7 - Furnace Only Mode Operation Note: Table 7 operation may be different based on the Gap settings. See section Temperature Gap (Hysteresis) for details. Note: All heat modes are subject to Auto Gas Changeover Operation when enabled. See section Auto Gas Changeover in Operating the Thermostat for details.
Auto Gas Changeover Note: See section Auto Gas Changeover in section Initial Setup Instructions for enabling and disabling this feature. 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. All three stages may not be available based on your system, but EasyTouch will output the same logic. Stage 2 heating is available in every system.
Local Weather and Local Time Local weather is displayed on the main screen and shown visibly in section (2) Local Weather under section Main Screen. Tapping the button will reveal more detailed weather information of the last received weather data. The local temperature is displayed in the lower left corner of the main screen, as shown in section (11) Outside Temperature. A valid location and an internet connection on the thermostat are required to retrieve weather data.
Settings Screens The settings screens allow for further configuration and control of the thermostat. It is a paged system that you can navigate through to see all available settings. Each setting button can be tapped to configure the related settings. Note: Not all settings may be available depending on your EasyTouch RV model. If you do not see the graphic then it is not available for your system. Settings Button Tap the settings button as shown in section (9) Settings under Main Screen to view them.
Bluetooth (Account) Password Reset This screen is used to reset the saved Bluetooth password in the thermostat. This is the password that must match your EasyTouch RV app account to make remote connections. Only one account can have access to the thermostat. Use this whenever you reset the Bluetooth Password Reset password to your app account to regain remote access to the thermostat. Temperature Reading Adjustment This setting allows you to calibrate the Inside temperature reading with an offset.
Dip Switches This setting is used to configure your thermostat’s operational settings and is slightly different for each EasyTouch RV model. Some simply display how the air conditioner control board that EasyTouch RV communicates with is configured. Others allow for telling EasyTouch RV what appliances it has connected to it. Tap the Switches button to see what configurations are available. See section Initial Setup Instructions for details on what must be configured, if any.
Schedule Screens The schedule supports 7 day per week scheduling of events. Events can include changes to the set point or mode of operation for one or more zones. Figure 3 shows the main schedule screen. The smart device application also offers a method to copy days. Once a schedule is set for one day, it can be copied to any other day. (1) Day of the Week Day of the week is selected from the days along the top of the screen. The day selected appears in white.
Figure 4 shows the edit screen when an event is tapped as shown in (2) Scheduled Events on the main schedule screen. The event on the main screen and action time in the edit screen will show disabled until a time is set. Press “Disabled” (1) at the top of the screen to show a gray box around the disabled selection. Use the up and down arrows to make a change. The up and down arrows change to full color once a selection is made. Use the back arrow (2) to save any changes and leave the screen.
Smart-Device Application Features Restart Thermostat This Bluetooth only feature allows resetting the display just as if you removed and restored power. Calibrate Touchscreen It is normally not necessary to recalibrate the touchscreen. This selection prompts the user to press the four corners of the display then test the calibration using three diagonal marks. This feature is only available from Bluetooth as being at the thermostat is required.
Appendix A: Working Wirelessly This thermostat may be operated remotely using either Bluetooth or Wi-Fi. All connectivity is performed through the EasyTouch RV App on a smart-device. The app is downloaded from the Google Play store or Apple App store. The first time the app is opened, it will ask to create an account. Create your account and follow the prompts to connect your thermostat. EasyTouch RV App icon Bluetooth is a limited range method to connect, typically used when near the thermostat.

Appendix B: Troubleshooting The most common problems during installation are not matching the wires correctly or properly mating the wires. The first step should always be to recheck the instructions and make sure the wires are joined and seated properly. The second most common problem is not knowing the thermostat operation. If the system is running a heating or cooling cycle, the set point will turn red for heating and blue for cooling.
