APC ACPCW40-150 User Manual

The display interface is standard on 
each system.  The display interface 
provides precision control for the 
demanding requirements of these 
environments: 

•  Data centers
•  Control rooms
•  Clean rooms 
•   Switch  rooms 
•   UPS  rooms

The easy-to-use display allows the operator to select options from the display interface to control and monitor 
the InRoom precision air conditioning system.

Logging
The display interface displays the most recent alarms.  Each alarm log contains a time/date stamp as well as 
operating conditions at the time of occurrence.  The display interface also displays run time, in hours, for major 
components (compressors, heaters, humidifier, fans).

Control Type
The display interface utilizes proportional and integral derivative (PID), a time-proven precision 
environmental control method.  This allows for custom tuning of control variables to achieve the desired 
system response.

•  Audible and Visual Alarms
•  Sensor Status (Temperature, Humidity, and Pressure)
•  Component State (On/Off, %)
•  Component Runtimes
•  Event Logging
•  Configuration and Alarm Settings
•  Password Protection

Open Architecture
The InRoom precision air conditioning system is open for integration with all building management systems. 
The display interface on the system supports Modbus RTU RS485.
