10 APC NetworkAIR CM Series: Optional Features

Setpoints. The microprocessor is provided with independent setpoints for:

Automatic setpoint crossover protection will prevent the setting of the heat

setpoint above the cool setpoint and the humidify setpoint above the

dehumidify setpoint. Setpoint adjustment can be restricted to only operators

with knowledge of the security codes set within the security menu structure.

Configuration. Flexibility is offered through the use of the configuration

menu. Operating requirements are satisfied by changing the configuration

settings. New configurations are stored in EEPROM and protected from

unauthorized tampering by the four-digit security password, selected in the

security menu.

Configuration options include:

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.
