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 ALR and WHR units is always the
successive pressing of the following "ACTION" group keys:
"Enter" "Enter" "Enter" "Enter"
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 may make any necessary
set point 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.
Keypad Key Functions
The MicroTech keypad consists of twelve pressure sensitive membrane switches (refer to Figure 14). These
keys are used to step through, access, and manipulate the information in the MicroTech controller tree
structure. The keypad keys are divided into four groups with two or four keys in each. These groups of keys
and their functions are described below.
Category group
The keys in this group provide quick access to strategic menus throughout the menu tree-structure. This
reduces the need to step through all the menus, one by one, in order to reach the desired menu.
Status—Pressing the "STATUS" key at any time shifts the display to Menu #1 (Unit Status) which is the first
menu of the Status category.
Control—Pressing the "CONTROL" key at any time shifts the display to Menu #13 (Control Mode) which is
the first menu of the Control category.
Alarms—Pressing the "ALARMS" key at any time shifts the display to Menu #24, (Circ 1 Current Alarm)
which is the first menu of the Alarms category.
Switch—Pressing the "SWITCH" key at any time toggles the display between the current menu
(status/control) item and the related menu (control/status) item somewhere else in the tree-structure. For
example, if this key is pressed while the current menu item is Menu Item 4A (Leaving Evaporator=), the display
shifts to Menu 14B (Leaving Evaporator Set Point=).
This provides for easy review of actual versus set point values. Table 7, Table 8 and Table 9 include a listing
of all the currently supported switching functions.
Menu group
The keys in this group are for stepping from menu to menu in the menu tree-structure.
Prev.—Pressing "PREV." shifts the display to the previous menu. Note: When Menu #1 is currently in the
display (the first menu in the menu tree-structure), pressing "PREV." causes an "end of menus" message to
appear in the display. Pressing "PREV." again causes the display to wrap around to Menu #27 (the last menu
in the tree-structure).
Next—Pressing "NEXT" shifts the display to the next menu. Note: When Menu #27 is currently in the display
(the last menu in the menu tree-structure), pressing "NEXT" causes and "end of menus" message to appear in
the display. Pressing "NEXT" again causes the display to wrap around to Menu #1 (the first menu in the menu
tree structure).
