Using the MicroTech III Remote User Interface
Introduction
The remote user Interface keypad/display consists of an 8-line by 30 character display, a “push and roll”
navigation wheel, and three buttons: Alarm, Menu, and Back (see Figure 10). The navigation wheel is used
to navigate between lines on a screen (page) and to increase and decrease changeable values when editing.
Pressing the wheel acts as an Enter button. When the Back button is pressed, the display reverts back to the
previously displayed page. When the Home button is pressed, the display reverts to the main page. When
the Alarm button is pressed, the Alarm Lists menu is displayed.
The following section describes how to set up the remote user interface so that it can be used to display,
configure, or change unit parameters. For instructions on how to use the remote user interface, refer to the
applicable MicroTech III Unit Controller Operation Manual for a detailed description of chiller or rooftop
sequence of operation and keypad menu structure (available on www.daikinmcquay.com).

Setting up the Remote User Interface for Use
Once the remote user interface has been installed, (see Installation section of this manual for instructions) it is
then possible to configure user preferences and synchronize it with the main unit controller by following these
steps:
1. Turn power on to the unit controller(s). Power to the Remote User Interface is provided
automatically from the unit controller(s) through the RS-485 direct or twisted pair connection.
2. The main screen with HMI Settings and Controller List appears (see Figure 11).
Note: The main screen can be accessed at any time by pressing the Home button for several seconds.
