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.

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 14.3 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.
