Data Alarm Processor III
(DAP™ III)
Data Aire’s Data Alarm Processor III (DAP III) continues the tradition of advanced electronic devices from
Data Aire for monitor and control of computer room air conditioning units which began in 1977, over thirty years ago.
Each generation of these devices has provided more accurate monitoring information and flexibility in controlling the
unit. The DAP III, microprocessor, based on the popular non-proprietary protocol, Modbus RTU, is equipped with
flash memory and along with the standard USB port permits fast and easy software updates. The modular design
offer installation and upgrades flexibility. Should you need to upgrade your unit simply pop in a new board. As in the
past the DAP III communicates directly with all major building management system (BMS). Just add a communica-
tions card and you are connected. One new exciting feature of the DAP III is a real time clock allowing you to pin-
point problems, precisely knowing what occurred and when. A new hierarchal menu structure permits easy and fast
access making programming simple.
The DAP III is the latest in microprocessor design and will keep your computer room air conditioning unit running ef-
ficiently for a long time.
While the DAP III has two distinct looks they are identical as far as program and function. This Operation Manual cov-
ers both the unit and wall mount.
The unit mounted DAP III panel, shown to the left,
comes standard on all floor mount Data Aire units.
The wall mounted DAP III panel, shown to the right, is
standard on all Mini-Plus, LCS, and Shelf units. It can
also be an option on the Mini and floor mounted units.

5
Modes of Operation - The DAP III has two modes of operation. The Operation mode is the prevelant mode
and occurs when the unit is in normal operation. During this mode the top row of the display shows the current opera-
tion which the unit is in, such as: humidification, dehumidification, reheat stage - either 1,2 or 3 depending on how the
unit is configured; cooling stage - either 1 or 2 again depending on the configuration of the unit; and energy saver. If
none of these condition exist a display of “Data Aire System Ready” will be shown. The lower row will continuously
scrolls through the following displays: date and time set in the DAP III program; unit number and zone number (Pro-
viding the unit is connected to a network. If not connected to a network it will display “N/A.”) as programmed; current
temperature and humidity detected by the return air sensors or if the optional remote sensors are used it will be the
conditions the remote sensors record; then any alarm conditions currently active. (A listing of these alarm conditions
are shown on page 11.) If your unit uses chilled water DAP III will display the percentage of chilled water flow as well.
In the upper right-hand corner of the DAP III display you should find a blinking form in the shape of a heart. The blink-
ing indicates that the processor is functional.
The second mode of the DAP III is the Menu Mode which is described in the balance of this manual. To enter the
Menu Mode depress either of the MENU buttons.
DAP III Buttons - On the front of the DAP III there are seven buttons: an ON/OFF, MENU UP ()and MENU
DOWN () button; SELECT UP () and SELECT DOWN () button; SILENCE /ALARM button and an EXIT button.
The ON/OFF button is a soft power on/power off button. The hard power ON/OFF switch is located on the DAP III
Control Module circuit board and will be explained in the next section of this manual.
SILENCE /ALARM button only function is to mute audio alarms, the button is sparingly used in programming.
EXIT button has no function in the operation mode, however, it is used in the menu mode. Once in the menu mode
when the EXIT button is depressed the values programmed are saved and takes you up one level. For example if
you are in the Menu Groups, as shown on the top of page 13, depressing the EXIT button will take you to the opera-
tion mode. However, if you are in a Sub-Menus, shown on pages 13-15, depressing the EXIT button will take you to
the Menu Group for that sub group. For example if you were in sub-menu group 4-6 Firestat Temperature Alarm Limit,
depressing the EXIT button will take you to Menu Group 4 -Alarms .
MENU / MENU these buttons primarily allow you the scroll up or down in the menu grouping that you are in
currently. If you are in the Group menus depressing the MENU button will take you to the next higher menu, from
Group1 - Status & History to Group 2 - Setpoints. Conversely pressing the MENU button will take you to the next
lower menu in that grouping, from sub group 8-5 Set-Back Reheat depressing the MENU button would take you
to sub group 8-4 Set Up Cool. (All menu grouping continuously scroll, once you reach the last menu option and you
depress the MENU button you will return to the first menu option.) These buttons have other specialized functions
depending on the subgroup menu you are addressing. These functions are described in the body of this manual in
the section where they apply. If the MENU buttons are held down they will advance at a rapid rate. If there is no but-
ton activity for three minutes the DAP III will return to the Operation Mode.
SELECT /SELECT these buttons, as the name implies, allows you to select a menu once you have located it
using the menu buttons. For example if you wanted to select the sub group menus for “Group 3 - Operation,” once
you scrolled to the group using menu buttons - depress the SELECT button will take you to “3-1 - Set Time and
Date,” the SELECT button would take you to sub menu “3-16 - Humidification Desaturation Cycle” the last menu
option in sub-menu group 3 Once in sub group menus the SELECT and SELECT buttons permit you to scroll
through that menu’s options..

6
Hard Power ON/OFF Switch - After supplying power to the unit, if the DAP III does not come on when you
press the soft ON/OFF button on the cover of the DAP III it will be necessary for you to open the cover of the DAP III
The DAP III can be shipped in three different configuration of circuit boards; the basic DAP III board; the DAP III with
the relay board; and DAP III with the relay and analog boards. Each of these configurations are shown below and on
the following page. The configuration in your unit is dependent on the type of cooling and options that was selected.
One of these photos will match the circuit board that is in your unit. However the hard ON/OFF switch is in the same
position on all boards

PUSH BUTTON FUNCTIONS
The Data Alarm Processor-III panel has seven pressure sensitive feedback-type buttons on the face of the panel. All
programming functions and/or settings are done from the face of the panel. Their functions are as follows:
IMPORTANT NOTE:
The RAM SIGNATURE test often displays “FAIL” on initial start-up because the RAM does not have any stored data.
Simply press “SELECT” to bypass the “FAIL” message. Once the processor is on-line and operating, the RAM will
collect data and the test should pass on future restarts. On start-up, remember to remove the protective paper on the
battery before turning the unit on. Otherwise, the RAM SIGNATURE will fail on future restarts.
Each time a MENU or SELECT button is pressed, it will advance to the next menu, sub-menu, or selection. If the button
is held down, the menus or selections will advance at a rapid rate. If there is no button activity for three (3) minutes the
panel will return to its normal operating mode.
When a menu first appears, it will have a menu number and title. The first time a SELECT button is pressed, the current
value or option in memory is displayed. Additional pressing of a SELECT button will cause alternate values, options
or selections to be displayed. The SELECT button should be pressed until the desired value, option or selection is
displayed. After the desired value, option or selection has been chosen, the MENU button is pressed to save the last
displayed entry into memory and to advance to the next menu display. The EXIT button can be pressed at any time
to return the panel to its normal operating mode. In this mode, the panel will scroll and display the current system
functions, temperature, humidity and ID number. If an alarm is present it will also be displayed.

NOTE: MENU groups 2 thru 11 require password entry, once a password has been set.
The correct password will allow the user to set/change all sub-menus in Groups 2 through 11. It will also allow the
user to view all factory locked menus (Sub menu 4-24, Group 5 – Configuration and portions of Group 6 - Network).
To access the factory locked menus, a specific button sequence is required. Neither the password nor the button
sequence will be required again until the user has exited from the menus to operation mode, either by pressing the
EXIT button or by allowing three (3) minutes to elapse with no button activity. FOR LOCKED MENU ACCESS – SEE
PROCEDURES TO UNLOCK GROUP 5 MENUS. DAP-III panels are shipped with the password set at 00, indicating
no password set. If a password has been set and is unknown, the number 40 can be entered to allow viewing access
to sub-menus 2-10. 40 should never be used as a defined password. This is a temporary bypass to allow verification
of the programmed password and will be deleted when the EXIT button is pressed or when three (3) minutes has
elapsed without button activity.
MENU Display will read: ENTER PASSWORD FOR ADDITIONAL MENUS
PASSWORD: nn
