1.0 INTRODUCTION
The Mini dap4 continues the tradition of advanced electronic devices from Data Aire for monitoring and control of
computer room air conditioning units which began in 1977. Each generation has provided more accurate monitoring
information and exibility in controlling the unit.
The Mini dap4 offers the denite answer for precision environmental control. The Mini dap4 control system not only
controls and monitors temperature, humidity, airow and cleanliness, but also provides component run times, alarm
history and an automatic self-test of the microprocessor. All messages are sequentially displayed on a backlit LCD
(liquid crystal display). The Mini dap4 can interface with a variety of building management systems (BMS).

2.0 GETTING STARTED
The Mini dap4 consists of two main components: the control module and the display panel. The control module is
located in the electrical panel. The display panel is remotely mounted. The two are connected by special telephone
type cable harness (units may be ordered with longer cables for optional remote wall mounting).
Note: Factory cable is required. This is a custom made cable and must be ordered from Data Aire. A regular tele-
phone cable will not operate.
All data displayed on the display screen originates from the control module. The display panel has a backlit LCD (liq-
uid crystal display). There are six keys on the face of the display panel to retrieve or enter settings.

The main loop will ip though a series of screens that allow you to see set-points, current unit status (temperature,
relative humidity and operating mode – cooling, humidication, etc.).
2.1 POWERING the Unit ON/OFF
Before powering unit ON, check that power is available and proper connections have been completed.
Turn the disconnect switch to the ON position. The controller display keys and screen will illuminate and the proces-
sor will conduct a self-test (the screen will remain illuminated with no messages until the testing is complete). The
self-test takes approximately 20 seconds. Once completed, the Main Menu screen will be displayed. For initial pro-
gramming of setpoints, alarms, delays, etc., it is not necessary to have the unit ON. With the unit in the “OFF by Key”
mode, all settings are available to view and change (other than Menus J – Factory Settings and L – Congure Inputs/
Outputs) if the proper password is entered.
The Main Menu screen will display the unit type, date and time, and unit status. In addition, the screen will scroll and
display the temperature, relative humidity and operating mode.
The Unit Status will indicate the unit: ”OFF by Key”
The unit may be turned ON at any time. Hold the ESC key for approximately 5 seconds. The display will continue to
scroll and display messages. At the same time the unit status is changed to “Unit On”. Once powered there will be a
5-600 second start delay indicated by “Time Before Start: XXs”.
Note: The start time delay is programmable from 5-600 seconds (Menu J – Factory Settings). The factory setting is 5
seconds.
2.2 ACCESSING MENUS/PASSWORDS
To access any Menu a numerical password is required. There are two levels of password:
• SERVICE LEVEL • FACTORY LEVEL
The SERVICE LEVEL password allows viewing and changes to the following Menus:
A. On/Off D. Input/Output G. Network Conguration K. Alarms/Limits
B. Setpoint E. Historical Data H. Calibrate Sensors
C. Clock/Scheduler F. Information I. Manual Control
The FACTORY LEVEL password allows changes to the SERVICE LEVEL Menus plus the following Menus:
J. Factory Settings L. Congure Inputs/Outputs
The ZONE MASTER is an optional feature and requires a factory provided activation code. Contact factory if ZONE
MASTER control is required.

To enter the Menu and Sub-Menu screens, press the MENU key on the display panel. A password will be requested.
The password is a four digit entry (including 0). Units are shipped from the factory with the password requirement
bypassed to accommodate start-up and set-up.
The display screen will have the following message:
The Service Level Password setting from the factory is: 0000
The cursor will be ashing at the top of the screen. Press the ENTER key to move the cursor to the rst eld. Press
the UP or DOWN keys to increase or decrease the value. Once the value is entered, press the ENTER key to move
to the next input. Increase or decrease t
he value by pressing the UP or DOWN keys. Once the desired value is shown,
press the ENTER key to move to the next eld.
Once the correct password is entered and accepted, the Menus will display on the screen. Only those Menus allowed
through the Service Password will be available. Use the UP or DOWN keys to scroll through the available Menus.
Note: Factory Level Menus are for conguring the unit. The Mini dap4 controller is used for a variety of equipment
types. The controller is based on the unit type, unit components and options. Under normal circumstances these
menus should not be changed. If they need to be changed, please consult with Data Aire engineering or service per-
sonnel before proceeding.
2.2.1 Changing the Service Level Password
The Service Level password can be changed while the service level menu is active.
▼ After entering the Service password press Menu key again then press Down key, the screen will display the follow-
ing message:
▼ Press the ENTER key. The cursor will highlight the rst input. Change the input by pressing the UP or
DOWN
key.
Once the selected number is displayed, press the ENTER key to move to the next input. Repeat the same steps for
each input.
After the last input has been entered the new password is stored. Press the MENU key to return to Main Menu.

3.0 ENTERING MENU SETTINGS
3.1 MENU A – ON/OFF
Use the UP or DOWN key to scroll through the menus. Once the desired menu is highlighted, press the ENTER key.
MENU A allows Start-Up Delay Time, Start-Up Mode and ON/OFF to be changed from the factory settings (the Ser-
vice Level password is required for entry).
The following will appear on the display screen:
The cursor will be ashing at the upper left hand corner. Press the ENTER key. The cursor will move to the “Start-up
Delay”. The start-up delay is the time before the blower starts after being powered ON and the processor has com-
pleted its self-test. Press either the UP or DOWN button to change the delay time. The range is 5 to 600 seconds.
Once a time is selected, press the ENTER key to save the setting and move to the next line “Start-Up Mode”.
Press the UP or DOWN keys to change the mode from ON to OFF or from OFF to ON. The setting will determine
what the unit will do if power is interrupted. With the setting ON, the unit will automatically start once the self-test is
completed. With the setting OFF, the unit will require manually starting by holding the ESC key for ve (5) seconds.
Depending on which selection is made (ON or OFF), the Status will display – Unit On or Unit Off by Key
Once selections are made, leave MENU A by pressing the MENU key. The Main Menu screen will continue to display
other menus (B, C, E and F). To look at any of these menus scroll to the desired menu. Press the ENTER key. If you
choose to return to the Main Screen, press the ESC key.
3.2 MENU B - SETPOINTS
MENU B allows viewing and changing of Setpoints (Service Level password is required for entry)
Press the UP or DOWN key until “B. Setpoint” appears and is highlighted. Press the ENTER key.
Use the UP or DOWN key to scroll through the screens. Menu B has two screens.
The following will appear on the rst Menu B screen (values are for reference only):
On/Off Unit
Start-up Delay: 5s
Start-up Mode: On
Hold ESC for 5 seconds
to turn unit ON or OFF
