• Turn the navigation wheel clockwise (right) or counterclockwise (left) to navigate between lines on a screen and to increase/decrease changeable values. Press down on the wheel to use it as an Enter button.
• Press the Back button to display the previous page.
• Press the Home button to return to the main screen from the current page.
• Press the Alarm button to view the Alarm Lists menu.

Keypad/Display Features

The first line on each page includes the page title and the line number to which the cursor is currently "pointing." Line numbers are X/Y to indicate line number X of a total of Y lines for that page. The left-most position of the title line may include an "up" arrow (indicating pages above), a "down" arrow (indicating pages below), or an "up/down" arrow (indicating pages above and below) the currently displayed page.

Each line can contain status-only information or changeable data fields. When a line contains status-only information and the cursor is on it, all but the value field is highlighted (white text with a black box). When the line contains a changeable value and the cursor is on it, the entire line is highlighted.

Each line may also be a "jump" line, meaning pushing the navigation wheel causes a jump to a new page. An arrow displayed to the far right of the line indicates it is a "jump" line, and the entire line is highlighted when the cursor is on it.

NOTE: Only menus and items applicable to the specific unit configuration are displayed.

Frequently Asked Questions

1. Is a separate 24V power supply necessary for direct connection?
   No, power is provided by the MicroTech unit controller.
2. What type of cable is recommended for daisy-chain connection?
   Daikin Applied generally recommends using twisted pair, 16 AWG shielded cable up to 500 ft and 14 AWG from 500 to 1000 ft. Contact the appropriate Technical Response Center for applications requiring longer distances.

How do I know if or when I need to upgrade the remote user interface (HMI) firmware files?

• If the remote user interface seems to freeze during initial download process.
• If wiring has been confirmed (inputs and outputs are polarity sensitive) and HMI is not responding.

See Firmware Upgrade Procedure section for details.

What if I want to upgrade the MicroTech unit controller firmware?

Contact either the Daikin Applied Air Technical Response Center at (800) 432-1342 (AAHTechSupport@daikinapplied.com) or the Chiller Technical Response Center at (800) 432-1342 (CHLTechSupport@daikinapplied.com) for assistance.

Helpful Tips

Service technicians often find it convenient to have two keypad/displays connected to a single unit controller. Using a split-screen setup makes it possible to view multiple menu items at the same time during start-up and also for diagnostic purposes.

• Simply hook up the first remote user interface with an RJ45 direct connection, and then use a two-wire twisted pair cable to connect to the second keypad/display.
