Unit Operation
Maintaining Control Parameter Records
Daikin recommends that the MicroTech 4 controller’s setpoints
and parameters be recorded and saved for future reference. If
the Microprocessor Control Board requires replacement, this
record facilitates entering the unit’s proper data. The following
tables display all the setpoints, monitoring points, and program
variables offered by MicroTech 4 plus the keypad road map
used to find each parameter.
A number of menus and menu items that appear on the unit
keypad/display are conditional and may not apply to a specific
unit, depending on the unit software configuration. The unit
software configuration is defined by a “Software Configuration
Code” shown on a label located near the keypad/display. The
Software Configuration Code also can be displayed via the
six menu items in the Config Code menu on the unit keypad/
display.
NOTE: Keep a record of any changes made to any of these
items.
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.
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.
Figure 125: Keypad Controls
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 need 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.
Various menu functions are accessible or inaccessible,
depending on the access level of the user, and the password
they enter, if any. There are four access levels, including no
password, Level 2, Level 4, and Level 6, with Level 2 having
the highest level of access. Without entering a password, the
user has access only to basic status menu items. Entering
the Level 6 password (5321) allows access to the Alarm Lists
Menu, Quick Menu, and the View Status Unit Menus group.
Entering the Level 4 password (2526) allows similar access
as Level 6 with the addition of the Commission Unit Menu,
Manual Control, and Service Menu groups. Entering the Level
2 password (6363) allows similar access as Level 4 with
the addition of the Unit Configuration Menu. To access the
advanced menu, you need to enter a level 2 password and set
the enable advanced menu flag to Yes in the service menu.
Continuing without entering one of these three levels allows
access only to the Alarm Lists Menu and the System Summary
