Introduction - Data Aire dap4 User Manual

Introduction

The 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 and application
flexibility.
Control -
The dap4 offers the definite answer for precision environmental
control. The dap4 control system not only controls temperature, humidity, airflow
and cleanliness; it provides component run times, hourly duty cycles and 24 hour
temperature and humidity deviations.
Efficiency -
Airside and waterside economizers are available to help conserve
power usage. Features like "Humidity Anticipation" offsets the humidity set point
to reduce excess humidification and dehumidification. Options such as a variable
compressor also contribute to energy savings.
Alarm Management -
The dap4 offers extensive alarm management. An
array of alarms conditions may be enabled, and some can be set to stop
operations or completely shut down the unit. Up to 200 of the most recent alarms
are stored in an alarm log. Each alarm has temperature and humidity readings
and the date time it occurred to assist in diagnosing what caused the alarm. There
are four alarm relay contacts that can be programed to energize for any multiple
of alarm conditions.
NOTICE... Please don't let the size of this manual overwhelm
you, as it covers many options and features of the dap4 that
may not apply to your specific application.
