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 nd each parameter.
A number of menus and menu items that appear on the unit
keypad/display are conditional and may not apply to a specic
unit, depending on the unit software conguration. The unit
software conguration is dened by a “Software Conguration
Code” shown on a label located near the keypad/display. The
Software Conguration Code also can be displayed via the
six menu items in the Cong Code menu on the unit keypad/
display. Refer to OM 920.
The shaded menus and menu items in Figure 118 starting
on page 114 are conditional. A conditional menu or menu
item includes a reference in Figure 118 to the position in the
Software Conguration Code upon which its applicability
depends. For example, the Duct Pressure menu in Figure 118
includes a notation [14=1 or 2]. This notation means that the
Duct Pressure menu (and all its menu items) applies to the
specic unit only if position 14 in its Software Conguration
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 Figure 118 include the factory-set value for all
adjustable items.
NOTE: Keep a record of any changes made to any of these
items.
