Using The Controller - Daikin WGZ030DW Operating And Maintenance Manual

Using the Controller

Getting Started
There are two basic procedures to learn in order to utilize the MicroTech II controller:
•
Navigating through the menu matrix to reach a desired menu screen and knowing where a particular
screen is located.
•
Knowing what is contained in a menu screen and how to read that information or how to change a
setpoint contained in the menu screen.
Navigating Through the Menus
The menus are arranged in a matrix of screens across a top horizontal row. Some of these top-level
screens have sub-screens located under them. The general content of each screen and its location in the
matrix are shown in Figure 10. (A detailed description of each menu begins on page 53.) There are two
ways to navigate through the menu matrix to reach a desired menu screen.
One is to scroll through the matrix from one screen to another using the four ARROW keys.
The other way is to use shortcuts to work through the matrix hierarchy. From any menu screen, pressing
the MENU key will take you to the top level of the hierarchy. The display will show ALARM, VIEW,
and SET as shown in Figure 8. This corresponds to the second row of screens on Figure 10. One of these
groups of screens can then be selected by pressing the key connected to it via the pathway shown in
Figure 8 on page 18.
For example, selecting ALARM will go the next row of menus under ALARM (ALARM LOG or
ACTIVE ALARM). Selecting VIEW will go the next level of screens under VIEW (VIEW UNIT
STATUS or VIEW UNIT TEMP). Selecting SET will go to a series of screens for looking at and
changing setpoints.
After pressing the MENU button, the top-level menu screen will show:
After pressing the "VIEW" menu button, a menu screen will show:
VIEW < COMPRESSOR
<
< EVAPORATOR
<
After pressing the "EVAPORATOR" menu button, the selected data screen will show:
VIEW EVAP
(screen data)
(screen data)
(screen data)
The arrow keys will automatically return to the "scroll" mode at this time.
MENU Key
The MENU key is used to switch between the shortcut method (known as the MENU mode and as shown
in Figure 8) and scrolling method (known as the SCROLL mode). The MENU mode is the shortcut to
specific groups of menus used for checking ALARMS, for VIEWING information, or to SET setpoint
values. The SCROLL mode allows the user to move about the matrix (from one menu to another, one at a
time) by using the four ARROW keys. A typical menu screen is shown in the following figure. Pressing
the MENU key from any menu screen will automatically return you to the MENU mode.
