Maintaining Control Parameter Records
Daikin recommends that the MicroTech III 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 III 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. Refer to
The shaded menus and menu items in
are conditional. A conditional menu or menu item
includes a reference in
to the position in the Software
Configuration Code upon which its applicability depends.
For example, the Duct Pressure menu in
a notation [14=1 or 2]. This notation means that the Duct
Pressure menu (and all its menu items) applies to the specific
unit only if position 14 in its Software Configuration Code is a 1
or a 2. Otherwise, the menu or menu item is not applicable to
the unit and does not affect its operation.
The items in
include the factory-set value for all
adjustable items.
NOTE:
Keep a record of any changes made to any of these
items.
