Supported Control Features
The EasyTouch has evolved and supports all of the features available in the original FX1 and in the
newest FX2 Control Boards. Please refer to the following chart below for the minimum required
firmware versions for the EasyTouch to support the control features required.
Table 1 – Control Boards & Options Supported by EasyTouch
1
One DC Blower output is integrated into base control board, and can support up to 2 DC blowers in
parallel
2
Four separate DC blower outputs are available on the daughterboard with individual fan speed
programming. The one DC blower output integrated into the base control board can still be used
and its speed settings follow that of Fan A.
This manual provides all necessary information for proper installation and operation of the
EasyTouch Display. Poor installation and misunderstood operating parameters will result in
unsatisfactory performance and possible failure.

4. OVERVIEW
4.1 EasyTouch Home & Main Screen Displays
The EasyTouch Home screen shown in Figure 1 consists of large, easy to read graphics, with large
buttons for basic control functions. The Main screen shown in Figure 2 consists of smaller graphics
showing all of the controls readouts and statuses, and had more buttons for all of the control
functions.
Figure 1 – Home Screen Display Figure 2 – Main Screen Display
4.2 EasyTouch Power-Up & Default Sleep Mode Screen Display
During power up and whenever the display enters Sleep Mode, the display shown in Figure 3 is
shown. While in Sleep mode, the graphic will move around the screen. See section 15.3 for more
information on the various Sleep Mode settings.

5. INSTALLING THE DISPLAY PANEL
5.1 Choosing the Location
Before mounting the control panel, consider the location. The display panel’s built-in air sensor
provides excellent room-air temperature sensing when properly located and installed. The physical
location of the air sensor is shown in Figure 4 and marked with “S”. Be sure to mount the display
panel on an inside wall, slightly higher than mid-height of the cabin, in a location with freely circulating
air where it can best sense average temperature. The display’s distance from the air conditioner must
be within the 15’ (4.5m) length of the display cable. Longer, custom cable lengths are also available.
5.2 Installing the Battery (for older EasyTouch models only)
Starting in second half of 2015, all EasyTouch display will be supplied with a rechargeable battery
that requires no installation or maintenance. Previous models will be supplied with a loose type
CR2032 battery that must be installed before mounting the display. The purpose of this battery is to
maintain the time clock and date calendar only whenever AC power is removed from the EasyTouch.
The battery has nothing to do with numerous programmable settings and features of EasyTouch, all
of which are stored in non-volatile memory that does not require a battery.

IMPORTANT:
Do not mount the display in direct sunlight, near any heat-producing appliances or in a
bulkhead where temperatures radiating from behind the panel may affect performance. Do
not mount the display in the supply-air stream. Do not mount the display above or
below a supply-air or return-air grille. Do not mount the display behind a door, in a corner,
under a stairwell or any place where there is no freely circulating air. If you cannot mount
the display in a suitable location for accurately sensing room temperature, install the
optional remote air sensor as explained in section 6.1.
5.3 Mounting the Display
1. Choose a wall location that has adequate depth (at least 1”/25.4mm) behind the wall itself. See
Figure 5 for the depth dimensions of the display.
2. Make the cut-out for the display panel as shown in Figure 6. Cut-out size is 2.900” (74mm) wide
by 2.165” (55mm) tall.

Figure 6 – EasyTouch Display Mounting Dimensions
3. Plug one end of the display cable (8-pin connector) into the display jack on the circuit board in the
electric box and the other end into the back of the display panel.
4. Secure the display panel to the bulkhead using the four screws provided.
Do not use a screw gun and do not over tighten screws when mounting, because either method
may damage the display.
5. When the display is securely mounted, mount the bezel over the display frame until it snaps into
place.
6. INSTALLING THE OPTIONAL SENSORS
6.1 Remote (Alternate) Air Temperature Sensor
Install the optional remote air sensor if the display cannot be mounted in a proper location for
accurately sensing room temperature. Installing the remote air sensor overrides the display’s built-in
sensor. The standard cable length for the remote air sensor is 7 feet (2.1m).
1. Mount the remote air sensor in a reliable return-air stream, preferably just behind the opening of
the return-air grille. DO NOT attach the sensor to the edge of the unit’s drain pan since the
condensate water and cold air spilling off of the heat exchanger coil will cause an inaccurate
temperature reading.
2. Plug its cable (6-pin connector) into the “ALT. AIR” or “ALT. AIR / RH” jack on the circuit board.
6.2 Outside Air Temperature Sensor
Install the optional outside air temperature sensor to monitor the temperature outside the cabin.
Outside air sensor cables are available in various lengths.
1. Mount the sensor outside but not in direct sunlight.
2. Plug its cable into the “OAT” jack on the circuit board.
6.3 Service Sensor (for DX systems only)
Install the optional condenser coil temperature sensor into the “OAT/H20” jack on the FX1 circuit
board or into the “SERVICE” header on the FX2 circuit board.
1. Mount the sensor in the middle of the condenser coil, strapping it securely to the piping.
2. Enabled the use of this sensor by going to DX Operational Settings, and then the Pump Sentry
feature as explained in section 12.3.5.
6.4 Water Inlet Temperature Sensor (for CW systems only)
When using the EasyTouch with a chilled-water air handler, plug the water-inlet sensor cable into the
“OAT/H2O” jack on FX1 or into the “OUTSIDE / RH” jack on FX2. Attach the sensor securely to the
