Menu Structure (general description)
The information stored in the MicroTech controller can be accessed through the keypad using a tree-
like structure. This tree structure is divided into Categories, Menus and Menu Items. There are three
Categories that make up the tree structure: STATUS, CONTROL, and ALARM. Each category is
divided into Menus and each Menu into Menu Items. The three categories are described below:
•
Status category
- Menus and menu items in this category provide information on the MicroTech
and unit operating conditions. The entries under each menu item in this category provide
information only and are not changeable through the MicroTech keypad. Menus 1 through 12 are
Status Menus.
•
Control category
- Menus and menu items in this category provide for the input of all the unit
control parameters. These include cooling and heating control, compressor control and condenser
fan control parameters as well as time schedules and alarm limits. The entries under these menu
items are changeable through the MicroTech keypad. Menu Items 13 through 23 are Control
Menus.
•
Alarm category
- Menu and menu items in this category provide information regarding current
and previous alarm conditions. Menus 23 through 27 are Alarm Menus.
Display Format
The information stored in the MicroTech controller tree structure can be viewed (one menu and menu
item at a time) through a two line by sixteen character LCD display. The current MENU is shown on
the top line and the current MENU ITEM is shown on the bottom line of the display.
Either Inch-Pound (I-P) or S.I. units can be displayed by installing the appropriate software.

MicroTech Menu Structure
1.
Status category - Where more than one menu item entry is listed under a menu item, the list
includes all the entries which can appear in the display for the particular item. The entry that
shows in the display depends on the operating status of the unit.
2.
Control category - Where more than one menu item entry is listed under a menu item, the list
includes all the choices from which the user can select. The selected entry appears in the display.
3.
Alarm category - The entries listed include all the possible alarm messages. The display will
show the current and previous alarm conditions for each circuit.
Password Information
When changing any menu item entry, the user is prompted to enter the access password. The change
will not be allowed until the correct password is entered. The password for AGZ units is always the
successive pressing of the following “ACTION” group keys:
“E
NTER
” “E
NTER
” “E
NTER
” “E
NTER
”
Once this has been done, the user can make changes to the menu item entries. After entering the
correct password, the controller will allow a 5-minute time period during which the operator can make
any necessary setpoint adjustments. Any keypad activity will reset the timer for the full 5 minutes so
the password only needs to be entered once per session. After 5 minutes of inactivity, the password
access time will expire providing protection against unauthorized users.
