Input/Output Points

Standard Input/Output points are Supply Air Temp, Outside Air Temp and Fan Proving Status. The following are

optional I/O points. See Network Interface unit diagram to see job specific I/O.

Display Use

The network interface controller is located in the unit

control panel. The face of the controller has six keys,

allowing the user to view unit conditions and alter

parameters. The network interface controller is pre-

programmed with easy-to-use menus.

The network interface controller will monitor the unit

conditions for alarm conditions. Upon detecting an

alarm, the controller will record the alarm description,

time, date and available temperatures for user review.

An optional digital output is available for remote

alarm indication. Alarms are also communicated via

BMS.

• Temperature Sensor Alarm: Network interface

controller will send an alarm in the case of a failed

air temperature sensor.

• Supply Air Low Limit: If the supply air temperature

drops below the supply air low limit (35°F), the

network interface controller can do one of the

following based on user setup.

- Alarm Only: Sends alarm via BMS.

- Alarm and Open NO3: Sends an alarm and turns

the unit run command off, even if BMS run

command is active.

- Disable: Disables the supply air low limit

function.

Alarms

Remote Display Panel (Optional)

A display panel allows for remote monitoring and

adjustment of parameters, allowing ease of control

access without going outdoors.

A remote mounted display is also available, which

connects via the J4 port. A six-wire patch cable is

needed.
