MicroTech III Controller Operation
Using the Keypad/Display
The keypad/display consists of a 5-line by 22 character display,
three keys and a “push and roll” navigation wheel. There is an
Alarm Button, Menu (Home) Button, and a Back Button. The
wheel is used to navigate between lines on a screen (page)
and to increase and decrease changeable values when editing.
Pushing the wheel acts as an Enter Button.
Figure 80: Keypad Controls
The first line on each page includes the page title and the line
number to which the cursor is currently “pointing”. The 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 includes an
“up” arrow to indicate there are pages “above” the currently
displayed items, a “down” arrow to indicate there are pages
“below” the currently displayed items or an “up/down” arrow
to indicate there are pages “above and below” the currently
displayed page.
Each line on a page can contain status only information or
include changeable data fields. When a line contains status
only information and the cursor is on that line all but the value
field of that line is highlighted meaning the text is white with
a black box around it. When the line contains a changeable
value and the cursor is at that line, the entire line is highlighted.
Each line on a page may also be defined as a “jump” line,
meaning pushing the navigation wheel will cause a “jump” to
a new page. An arrow is displayed to the far right of the line to
indicate it is a “jump” line and the entire line is highlighted when
the cursor is on that line.
The keypad/display Information is organized into five main
menus or menus groups; Alarm Lists Menu, System Summary
Menu, Standard Menus, Extended Menus and Advance
Menus.
NOTE:
Only menus and items that are applicable to the
specific unit configuration are displayed.
The Alarm Lists Menu includes active alarm and alarm log
information. The System Summary Menu includes status
information indicating the current operating condition of the
unit. Standard Menus include basic menus and items required
to setup the unit for general operation. These include such
things are control mode, occupancy mode and heating and
cooling setpoints. Extended Menus include more advanced
items for “tuning” unit operation such as PI loop parameters
and time delays. Advanced Menus include the most advanced
items such as “unit configuration” parameters and service
related parameters. These generally do not needing changing
or accessing unless there is a fundamental change to or a
problem with the unit operation.
Passwords
When the keypad/display is first accessed, the Home Key
is pressed, the Back Key is pressed multiple times, or if the
keypad/display has been idle for the Password Timeout timer
(default 10 minutes), the display will show a “main” page where
the user can enter a password or continue without entering a
password. The three password levels available are Level 2,
Level 4, and Level 6, with Level 2 having the highest level of
access. Entering the Level 6 password allows access to the
Alarm Lists Menu, System Summary Menu, and the Standard
Menus group. Entering the Level 4 password allows similar
access to Level 6 with the addition of the Extended Menus
group. Entering the Level 2 password allows similar access to
Level 4 with the addition of the Advanced Menus group. The
Level 2 password is 6363, the Level 4 is 2526, and the Level
6 password is 5321. Continuing without entering one of these
three levels allows access only to the Alarm Lists Menu and the
System Summary Menu.
NOTE:
Alarms can be acknowledged without entering a
password.
Figure 81: Password Main Page
The password field initially has a value **** where each *
represents an adjustable field. These values can be changed
by entering the Edit Mode as described.
Figure 82: Password Entry Page
Entering an invalid password has the same effect as continuing
without entering a password.
Once a valid password has been entered, the controller
allows further changes and access without requiring the user
to enter a password until either the password timer expires
or a different password is entered. The default value for this
password timer is 10 minutes. It is changeable from 3 to 30
minutes via the Timer Settings menu in the Extended Menus.
