	Configuration options include:
	• Fahrenheit or celsius display	• Alarm input polarity
	• Compressor minimum on time	• Alarm enable
	• Compressor minimum off time	• Temperature deadbands
	• Power loss restart time delay	• Humidity deadbands
	• Redundant unit grouping	• Small room delay
	Common alarm contact. A common alarm relay is installed on every
	microprocessor. In the event of an alarm condition, the relay will change
	state. The user can select which alarms change the state of the relay. This
	feature allows for remote enunciation of alarm status.
	Run times. The major components within the unit (motor, humidifier, and
	compressor) have independent run timers that monitor and store accumulated
	run hours on the components. The run timers are provided with operator
	adjustable run time alarms.
	Security. Multiple security levels prevent unauthorized adjustment of
	important system parameters. The user may select a four-digit password for
	setpoint and configuration changes. Should the password be forgotten, APC
	can provide temporary access.
	Monitoring. With the addition of a network communications card the
	microprocessor may interface with the locally installed APC remote
	monitoring and control system. Gateways are available for interfacing with
	building management systems. Please check with APC for compatibility with
	your building management system.
	Cool inhibit. Prevents the unit from over-cooling during the
	dehumidification cycle. If the space temperature falls below a user adjustable
	setpoint, cooling will become inhibited until the space temperature returns to
	setpoint.
	Cool override. A manual toggle switch will allow one compressor operation
	in the event of a microprocessor failure. The cool override can be field wired
	to a snap acting thermostat for cooling control.
	Remote shutdown. Events external to the unit, such as activation of a fire
	suppression system may require the unit to shut down remotely. Additionally
	this feature may be tied into a BMS that would allow remote control of the
	units on/off status.
	Remote relay shutdown. Remote shutdown of the NetworkAIR system
	can be done by a factory installed relay. The relay can be ordered with a 24,
	120, or 240 volt coil. The relay must be powered by others to disable the
	NetworkAIR system.
Overall cabinet	The frame is constructed of heavy gauge steel for maximum strength. Steel
	access panels are insulated for quieter operation. The unit has been designed
	for full service access from the front. The flush mounted panels are
	removable using convenient quarter-turn fasteners. The access doors for the

electronic controller and electrical panel can be opened without interrupting the operation of the unit.
