©2023 Micro-Air LLC Revision 2.1
The EasyTouch RV™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.
EasyTouch RV 356 Models and Compatible Replacements
EasyTouch RV 356 can be purchased in two colors. Table 1 lists all EasyTouch RV 356 models. The
obsolete thermostats are no longer sold, however their only difference was how to wire the unit. There is no
need to replace these models as operations and build quality were identical to the latest thermostats.

Installing the Thermostat
Came From Quick Start Guide? - Begin Here
You may have been directed here from the included Quick-Start Guide if it determined that you
need to do some additional setup. The directions needed are difficult to express without detail so please
read the full installation guide here to install your thermostat. This complete installation guide covers
everything in the Quick-Start Guide.
Safety
First, it is recommended to remove both AC and DC power from your system. Unplug your RV from
shore power and turn off any converters or generators to remove AC power. Open your 12-volt DC bus
breaker or fuse to de-energize your thermostat. This greatly reduces the chance of any harmful electrical
discharge, as well as preventing accidentally opening a fuse.
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, shown by Figure 4. 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 for all the thermostat
connections, which is also how EasyTouch RV is designed. This is
shown in Figure 5. This means you can simply unplug the
thermostat and proceed to the next section. Note that Figure 5
shows only one possible set of plugs and there may find more
or different plugs in your system.
Other RV builders do not use the proper plugs and direct wire
the thermostat to the RV manufacturers wiring using wire crimps
or similar. Some of them may use a mix of plugs and direct
wire. If the unit is direct-wired fully or in part then take some
Figure 4 - Inpect OEM Installation

pictures of this wiring for reference. Be sure that you can see
where the thermostat wires meet with the wall wires as they
are typically different colors. You can also write in Table 4
later in the section to record what color wires meet.
Wiring the Thermostat
Molex™Plugs
If your installation was done with the proper mating
Molex™plugs similar to Figure 5, then you can simply plug in
all the mating connectors and move on to the section Mounting
the Thermostat. The provided 9-pin (3x3) wire harness will not
be needed. Not all installations will use all plugs, just ensure
that every original plug has an EasyTouch match.
You may find the Molex™plug coming from the wall has a 3-pin plug and EasyTouch comes with a 4-pin
plug installed. Use the provided 4-to-3 pin adapter harness (Figure 1) in these systems, where the
orange/white wire is not used. If you have a 4-wire plug coming from the wall already then you will not
need the 4-to-3 pin adapter harness. If you find the 9-pin (3x3) is used but not a 4-or 3-pin then you will
use the relevant Direct-Wired section directions to complete the wiring.
If the plugs are not the standard Molex™plugs that mate with EasyTouch then you will have to wire it direct
as described in the Direct-Wired section. You could also make up your own plugs but is beyond what Micro-
Air can assist with.
Direct-Wired
The original thermostat in these systems will have wires coming out of the back of it that are
connected to the RV manufacturer’s wiring harness, using a crimp-splice or similar. The wire colors on the RV
manufacturer’s harness can vary, but the wires at the back of the original thermostat are always the same
color for their use.
Follow the thermostat wires the short distance to where they are spliced to the RV manufacturer’s wire
harness. Write in the RV wiring harness colors in Table 4 below before making connections. Take pictures if
you have not already for reference as well. Some thermostats and harnesses may not have all wires shown
in Table 4. The important part is that every original wire has an EasyTouch match.

Micro-Air provides a 9-pin harness (Figure 2) 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 (Figure 1) to EasyTouch. Strip away the black heat-shrink
on the orange/white stripe wire if the orange/white stripe wire is used. Cut off the 2-pin and 3-pin plugs as
needed and use electrical connectors (not provided) to complete the installation per Table 4. Any unused
wires or plugs you can cut short or leave untouched.
When you know where each wire goes you should begin cutting wires. Move through them one at a time,
replacing an OEM thermostat wire with the appropriate EasyTouch wire until all the wires are replaced.
Check for Additional Hardware –Software Setup for Later
You must check your wiring to determine what
additional hardware your system may have. Later, you will
use these findings to configure the software in EasyTouch RV.
Some of them had a freeze sensor while others used an AGS
(Auto-Generator Start) output, but never both. If an AGS
system was used, it was often in a Winnebago (TrueAir)
thermostat, but a freeze sensor is most common in general.
Inspect your OEM thermostat wires (Figure 6) for either two
gray wires or a green wire. A green wire means that you
have AGS. Two gray wires means that you do not have AGS.
See the Configure Auto-Gen Start section in Initial Setup
Instructions to tell the thermostat what you have. 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
(polarity does not matter) or connect your green wire to the
pin-3 gray wire of the Micro-Air 9-pin harness. Pin-3 is the
gray wire next to orange and red.
Re-apply Power
Restore DC power. The thermostat screen should light up and boot into the main menus. This will
happen if the four power wires are connected properly. All other wires control the outputs or are sensors.
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.

Mounting the Thermostat
Step 1: Locate the mounting bracket (Figure 3)
horizontally across the hole with the smaller
diameter of the mounting button against the wall.
Step 2: 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.
Step 3: 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.
Step 4: Remove the mounting tab before mounting
the thermostat on the wall.
Step 5: Aligning 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.

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 Setup button and
tap it. The first page is to configure the hardware in your specific system. 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 furnace are always enabled.
Configure Auto-Gen Start (AGS)
Some systems have hardware to allow for a generator to start prior
to a cycle occurring that needs it. These systems are commonly labeled
“TrueAir” and are often found in Winnebago products, but not all have Auto-
Gen Start (AGS). The hardware for (AGS) is not part of the thermostat but it
must be configured to know if it is available. Use section Check for Additional
Hardware –Software Setup for Later to know what you have.
Tap the AGS Available/Unavailable button under the “Auto Gen-
Start”heading to set it based on what you have. If set as “Available”then
the Generator button will appear and you can turn the functionality on or off.
Setting this to “Unavailable” is the default and should be used for all non-
AGS systems.
Warning: You MUST configure AGS availability appropriately or your thermostat may not function as
designed. You CANNOT enable this function unless you know you have the appropriate hardware. See
section Check for Additional Hardware –if you are not sure. This can also be found in your original
thermostat’s manual. Micro-Air cannot assist with acquiring AGS hardware.
Auto Gas Changeover Type
You can choose the auto gas changeover type by tapping the Type
button on the second page. Each “version”has slightly different logic to use
all of your available heat modes in stages based on how far the inside
temperature is from the set-point. Each version corresponds to a version of
the OEM thermostats behavior, as well as a “Disabled” option. Use the “GC
Ver” column of Table 2 and Table 3 to match the version to your original
thermostat. “Version A” has the broadest coverage if not sure.
You can also adjust parameters for the Auto Gas Changeover to operate its logic. The temperature at which
stages escalate can be set, as well as the maximum run time for a lower stage to escalate. See section Auto
Gas Changeover in section Operating the Thermostat for more details on this operation and the configurable
parameters.
Connecting Remotely
EasyTouch RV can be operated entirely by the touchscreen, however you can
also communicate, monitor, and modify operation of it wirelessly using the EasyTouch
RV application. Some extra features will require a wireless connection and is
described in their sections. See Appendix A: Working Wirelessly for details.

the difference between setpoint and inside temperature
•Cycled: Turns the electric fan on and off with a cycle at the selected speed only
•Manual: Always runs the electric fan at the selected speed
(3) Inside temperature
This is the temperature reading for the space that the thermostat is trying to temper, determined by a local
sensor. If a remote sensor is plugged into the back of the thermostat then it has priority over the sensor
installed in the thermostat from the factory. Use the (9) Info Screen to determine which is in use.
(4) Temperature Setpoint
This button shows the current temperature setpoint for the selected (1) Operational Mode. Tap it to adjust
the temperature setpoint. Setpoints are tied to each mode to remember the last setting. No setpoint button
means there is no setpoint control for the selected mode.

changes that are not common or found on the main screen. See section Settings Screens for more details.
(6) WiFi Status
The Wi-Fi indicator shows the state of the thermostat’s Wi-Fi connection. A dark blue icon means no connection
to an internet enabling device. Red means it is connected to an internet enabling device but does not have
internet. Green means it is connected to the internet. The number of bars indicate strength. See the Connecting
to a New Wi-Fi Network for more details.
(7) Local Weather
This icon indicates the local weather at the last time weather information was received. A Wi-Fi connection
on the thermostat is required to get weather data. Tap the icon for more detailed weather information. See
the Local Weather and Local Time section for more details.

Auto Modes
These modes will automatically switch between
heating and cooling cycles as needed. Their operation will
be the same as their “only” mode counterparts described
earlier in the Operational Modes section. 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.
This can be useful when setting a higher day-time cooling temperature and lower night-time heating
temperature. It can also be used to control the temperature extremes when you are away from the RV.
Note: These auto modes are subject to Auto Gas Changeover and Gap operations. See their Auto Gas
Changeover and Temperature Gap (Hysteresis) sections respectively for more details.

Local Weather and Local Time
Local weather is displayed on the main screen whenever Wi-Fi and internet is available, shown
visibly in the Main Screen section. Tapping the button will reveal more detailed weather information of the
last received weather data. The local temperature is displayed under the local weather.
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 saved in the thermostat when a Bluetooth connection
is made from a smart device with its location services enabled. You can check the current saved location from
the weather screen. 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, along with the above prerequisites.
Time is pulled in when a Bluetooth or Wi-Fi connection is made from the app. Also, an internet connection on
the thermostat will grab the time so long as there is a valid saved location. If power is interrupted or the
device is restarted, it will go out to the internet to grab the current time when the internet connection is re-
established, without app interaction.
Tapping the weather icon area, whether there is information there or not, will change to the weather screen
that will show the last valid weather data or weather troubleshooting information. If the main screen has a
temperature but no weather icon, it is defaulting to the outside sensor reading on thermostats that have one.
The information screen will always show the sensor reading if there is a sensor, and the weather screen will
always show the temperature reading from the internet. Systems without an outside temperature sensor
cannot add one.
Status Messages
Some messages may be displayed on the main screen as shown in section (10) Status Message
under Main Screen. Table 11 shows the potential messages and their meaning.
Message Text
Description
OPEN INDOOR SENSOR
The room sensor inside EasyTouch RV has failed open/disconnected or
shorted. It must be repaired, or replaced by an external AirXcel OEM remote
sensor using the green/white stripe wires of EasyTouch RV.
BAD INDOOR SENSOR
OPEN FREEZE SENSOR
The freeze sensor is open to say that the indoor coil has frozen up under
cooling operation and should be serviced as directed in the OEM manual for
the A/C unit. Cooling operation will resume when the sensor closes to indicate
it has warmed up.
If not, ensure that the sensor is installed to the thermostat correctly on the two
gray wires. AGS systems do not use a freeze sensor so ensure that the
thermostat is configured properly for AGS systems if used, as described in
the Check for Additional Hardware –Software Setup for Later section.
When 120 Volts AC is removed, the sensor no longer operates as expected
and reads open. This is OK and just a nuisance fault. The fault will clear when
power is restored. Power is needed to run electric appliances and the furnace
will run if the freeze sensor is open.
Also check that the fuse at the back of the thermostat is still good. Appliances
cannot turn on with an open fuse and the freeze sensor circuit will read open.
AUX HEAT ENABLED
This means that the two-hour timer of the Auto Gas Changeover logic is active.
See the Auto Gas Changeover section in Operating the Thermostat for details.

Home/Away
This setting changes from a home memorized set of settings to an away memorized set of
settings. It is like having two different thermostats, one while you are at the RV and one for
when you are not. Each can be set with a completely different set of modes, schedules, set
points and fan speeds to customize the operation with a single button press.
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 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. For
example, if the inside temperature reads 72°F (22.2°C) and you feel it is 75°F (24°C), you
can use the up and down arrows on this page to increment the offset to +3°F (+1.8°C).
Temperature Gap (Hysteresis)
This setting determines the difference in temperature required between setpoint and inside
temperature before a heating or cooling cycle will begin. This is helpful to prevent short
cycling in large spaces or spaces with high thermal loss, by running a cycle for longer
amounts of time. This offset is applied to all logic that involves setpoint operations, such as
auto modes, auto gas changeover, etc. See Table 12 for an operational example.

Setup
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. Micro-Air cannot assist with manipulating and adding more appliances to your
system.
Auto-Generator Start (AGS)
Warning: See Section Configure Auto-Gen Start in Initial Setup Instructions to configure this behavior
where appropriate.
This setting allows for a generator to start prior to any appliances that need line voltage to
run. EasyTouch RV will output voltage to its pin 3 grey wire to go to existing AGS hardware,
prior to calling for any appropriate cycles. It then disconnects voltage from this wire when
it is no longer needed. Tap the AGS Enable button to green to enable this behavior or to
gray to disable it.
Furnace/Aqua Icons
Most RV systems have auxiliary heat modes in the form of a “forced-air” gas furnace or
hydronic heat. EasyTouch RV or the associated control board treats these as the same output
and so you can tap the Furnace/Aqua button to toggle between what icons to display for
this operational mode. This is simply a cosmetic setting for all EasyTouch RV models except
the 350 model, which should be set appropriately.

Smart-Device Application Features
Restart Thermostat
This Bluetooth only feature allows resetting the display just as if you removed and restored power.
Check for Updates
Checks to see if any updates are available for the thermostat. The smart device application must
have internet and the thermostat must be connected to Wi-Fi with a green Wi-Fi symbol. Tap Check for
Updates and follow the prompts.
Note: Beta updates may be available from time to time, but these are for people working with Micro-Air in
testing them. Some features may not work as expected. The current version firmware can be restored by
checking for updates again.
Notifications
Notifications provide a way for the user to monitor the temperature in the space using notification
limits. Limits are set by connecting to the thermostat in the app, selecting the settings gear, and then selecting
notifications. A minimum and maximum allowed temperature can be set. Table 13 shows an example of
operation with an 80°F maximum temperature set.
A Notification will be sent for each degree it rises above the maximum temperature. If temperature drops,
no notification will be sent unless the temperature exceeds the last maximum temperature again (82 in the
example). If the temperature drops two degrees below the set maximum, (78 in the example) it will again
alert for each degree above the set maximum. This behavior helps avoid nuisance notifications to your smart
device. The same occurs in the opposite direction for the lower limit.
Edit Wi-Fi Settings or Connect to Wi-Fi
This is where you will make the connection from the thermostat to the internet. See section Connecting
to a New Wi-Fi Network for details on how to use this feature. The app must be connected to the thermostat
over Bluetooth to see this option.
Refresh Configuration:
This is a temporary feature that resets the saved configuration on the phone if a configuration change
is made at the thermostat, for example, enabling the heat pump mode for a zone from the Setup Settings
Screens.This will be removed later. If you experience a difference between the app modes available and
the thermostat modes available, then press this button to fix the issue.
