• Page 3: Installing the thermostat involves several important steps for safety and proper wiring. It is recommended to remove both AC and DC power from your system before starting the installation. Unplug your RV from shore power and turn off any converters or generators to eliminate AC power. Open your 12-volt DC bus breaker or fuse to de-energize your thermostat, reducing the risk of electrical discharge. The OEM thermostats have a front assembly that detaches from a back plate by rotating counter-clockwise. Take a picture of the wire colors as they enter their screw terminals for future reference. The backplate is attached to the wall by 2-4 mounting screws that need to be removed. The EasyTouch RV comes with 4 wires for making the necessary connections. Micro-Air provides connectors to interface the EasyTouch RV wires with the existing wires from the wall. A wire color chart is available to record the OEM wire colors and their corresponding functions.
• Page 4: Once you know which wires match to which, begin by using a small flathead screwdriver to loosen a wire’s associated screw terminal. Ensure that about ½” of insulation is stripped from the end of the wire. Open both levers of a connector and fully insert this wire in one end and close the associated lever. Warning: Be confident that you are making the right wire connections. Connecting the wires incorrectly may damage the EasyTouch RV thermostat. Restore DC power and the thermostat screen should light up and boot into the main menus. Restore AC power so that your appliances can run again. Move on to the section Mounting the Thermostat or the section Initial Setup Instructions and mount the thermostat later.
• Page 5: Initial setup instructions outline that the thermostat automatically detects available systems from the A/C control boards. No special software configuration is needed to start setting desired operation. Refer to the section on operating the thermostat for guidance on getting started. EasyTouch RV can be operated via the touchscreen or remotely using the EasyTouch RV application. Wireless communication allows for monitoring and modifying operation. Some features require a wireless connection, detailed in Appendix A: Working Wirelessly. The document includes a reference to the EasyTouch RV App icon. The revision date is November 22, 2022, version 1.2.
• Page 6: Operating the thermostat Main screen is where most time is spent using the thermostat. Inside temperature is determined by a local sensor. Local weather icon indicates the local weather at the last time weather information was received. Status tray shows various icons indicating active operations, including Wi-Fi connection status. Schedule icon indicates that the created schedule is active. Status message displays various messages indicating active operations. Temperature set point can be adjusted using the red and blue arrows. System power button turns the selected zone on or off.
• Page 7: Operational mode allows you to change the current operating mode depending on system availability. Available modes include Aqua Only, Furnace Only, Auto Mode, Cool Only, Dry Mode, and Fan Only. Fan speed can be adjusted by pressing the fan button, with options for Fan Auto, Fan Off, Fan Low, Fan High, and Fan Medium. Mood lighting settings can be accessed to select the lighting around the A/C plenum, with options to choose a color or turn it off. Zone selection allows you to cycle through available zones, with the selected zone indicated by a yellow box. Zone colors indicate status: Green for normal operation, Red for issues, and Gray for no communication. Settings can be adjusted by pressing the settings button, leading to additional configuration options. The additional status tray may display icons indicating active operations, including a freeze sensor reading for cooling modes. Outside temperature readings are retrieved via the thermostat’s internet connection as part of local weather information.
• Page 8: Operational modes operate the overhead fan and/or a heating or cooling cycle based on the current heating or cooling set-point, relative to the inside temperature. Fans and fan only mode lets the fan operate based on the chosen fan speed, circulating air without operating any heating or cooling cycles. Cool only mode runs a cool cycle to maintain the cooling set-point in the space, with a time delay of approximately three minutes before a cooling cycle begins to prevent compressor damage. Table 5 outlines the cool only mode operation, detailing conditions for cooling cycle initiation and continuation based on inside temperature relative to the set-point. Aqua only mode runs an auxiliary heating cycle to maintain the heating set-point in the space. Furnace only mode operates similarly, with the furnace fan speed not configurable from the thermostat. Table 6 describes the furnace only mode operation, indicating conditions for auxiliary heat cycle initiation and continuation based on inside temperature relative to the set-point. Notes indicate that operations in both tables may differ based on gap settings. Refer to the section on temperature gap (hysteresis) for further details. The document is a revision from November 22, 2022.
• Page 9: Dry mode attempts to remove humidity from the space using a set algorithm. Auto modes will automatically switch between heating and cooling cycles as needed. Auto modes 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 set-points. Auto mode can be useful for setting a higher day-time cooling temperature and lower night-time heating temperature. Auto mode is subject to gap operations. Press the set-points to toggle between which set-point you have selected. The upper set-point is for cooling and the lower set-point is for heating. Use the up and down arrows to change the selected set-point value.
• Page 10: Local weather is displayed on the main screen. Tapping the button will reveal more detailed weather information of the last received weather data. An internet connection and a valid location saved on the thermostat are required to retrieve weather data. Location is saved in the thermostat when a Bluetooth connection is made from a smart device with its location services enabled. New weather data is retrieved when there is a 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. Status messages may be displayed on the main screen. The room sensor connected to the A/C control board has failed and must be serviced or potentially replaced. The thermostat is not hearing any zones over the communication wires. The A/C control board has sensed that the DC voltage level is less than 10.5.
• Page 11: 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. Not all settings may be available depending on your EasyTouch RV model. Use these buttons to flip through all the available settings or return to the main screen. This screen displays a QR code that can be scanned to provide information about thermostat operation and troubleshooting. Day mode will dim the display down to the Sleep Level set in the Display Brightness settings. Night mode will turn the backlight completely off after 30 seconds of no screen presses. This screen allows you to set the Active and Sleep brightness levels used by the Day/Night Mode settings. Tap the enable/disable button to turn the schedule on or off.
• Page 12: Bluetooth password reset is used to match your EasyTouch RV app account for remote connections. Only one account can access the thermostat. Temperature reading adjustment allows calibration of the inside temperature reading with an offset. Temperature gap (hysteresis) determines the temperature difference required before a heating or cooling cycle begins, preventing short cycling. Measurement units setting determines how temperatures are displayed, allowing toggling between Fahrenheit and Celsius. Touchscreen calibration allows you to recalibrate the touchscreen by following on-screen prompts. Restart setting turns the thermostat off and on, simulating a power cycle. Reset all setting resets certain thermostat settings back to factory defaults, potentially clearing found zones and initiating a zone scan.
• Page 13: Dip switches are used to configure the thermostat's operational settings, varying by EasyTouch RV model. Some models display the configuration of the air conditioner control board, while others identify connected appliances. The switches button allows users to view available configurations. Refer to the initial setup instructions for configuration requirements. Micro-Air cannot assist with adding appliances to the system. The auto-generator start (AGS) setting enables a generator to start before appliances requiring line voltage. The AGS enable button can be tapped to activate or deactivate this feature. Most RV systems include auxiliary heat modes, such as forced-air gas furnaces or hydronic heat. The furnace/aqua button toggles the display icons for these operational modes. This setting is cosmetic for all EasyTouch RV models except the 350 model, which requires appropriate configuration.
• Page 14: 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. The smart device application offers a method to copy days. Once a schedule is set for one day, it can be copied to any other day. Day of the week is selected from the days along the top of the screen. The day selected appears in white. Events are numbered 1 to 6 along the left side of the display. Tap an event to edit it and advance to the schedule edit screen. System time is displayed along the bottom. Tap the time to change from 12-hour to 24-hour time format. A “--:--” is shown when time has yet to be set. Tap the back arrow to return to the last screen.
• Page 15: Figure 4 shows the edit screen when an event is tapped. The event on the main screen and action time in the edit screen will show disabled until a time is set. Press “Disabled” 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 to save any changes and leave the screen. Figure 5 shows the schedule edit screen once a valid time is set for the event. Set the event time by selecting hours, minutes, or AM/PM. Set the desired mode by tapping the mode button. Tap the hours, minutes, AM/PM or the set point to select an editable parameter, then use the red and blue arrow buttons to make a change. Tap the zone number to enable/disable the zone you want this event to affect. Create and enable a schedule by tapping the edit schedule button to enter the main schedule screen. Ensure that a valid system time is shown. Tap the day you want to set up a schedule for, then the event you want to edit. Tap the Action Time, Setpoint, and Mode to make edits to what you want your event to do. Tap the back button to return to the settings screen and this will save your schedule. Activate the schedule by pressing the schedule button with the “Enabled/Disabled” subtext.
• Page 16: Smart-device application features Restart thermostat allows resetting the display as if power was removed and restored. Calibrate touchscreen prompts the user to press the four corners of the display and test calibration. Check for updates verifies if any updates are available for the thermostat. Notifications enable monitoring of temperature using set limits. Limits can be set by connecting to the thermostat in the app and selecting notification settings. Notifications are sent for each degree above the maximum temperature set. Temperature drops do not trigger notifications unless the maximum temperature is exceeded again. Edit Wi-Fi settings is where the connection from the thermostat to the internet is made. The app must be connected to the thermostat over Bluetooth to access Wi-Fi settings.
• Page 17: 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. Bluetooth is a limited range method to connect, typically used when near the thermostat. If a second user is going to use the thermostat remotely, they must use the same account and password that the first user assigned to the thermostat. EasyTouch RV uses BLE which is a special implementation of Bluetooth. An account must be created for operation. Once the account is created, the application may ask to add a device. Enter your SSID (network name) and password of the network you want to connect the thermostat to. Follow the next steps if the account process does not add a control or a second thermostat is to be added.
• Page 18: Connecting to a new Wi-Fi network allows you to control the thermostat from anywhere using the app. The internet source must be a 2.4GHz network to connect to EasyTouch. To connect, access the thermostat via Bluetooth and select Wi-Fi Setup from the settings. The SSID will indicate searching and then switch to select. You can either choose a network or enter the SSID manually. After entering the password, press OK. A green Wi-Fi symbol will appear if the connection is successful, enabling remote access through the app. Updating the EasyTouch RV thermostat ensures you have the latest features. Confirm the thermostat is connected to Wi-Fi with a green symbol, then check for updates in the settings. Follow the prompts to update or verify the software version.
