Introduction

Program Features

The network interface controller is a device that acts as a communication link between the BMS (Building Management System) and the unit. The network interface controller will transform the communication into an action within the unit and will provide monitoring status of various functions and temperatures. The controller has the ability to communicate with a BMS through protocols such as LonWorks®, BACnet® MSTP, BACnet® IP or Modbus. See Points List at end of document for a complete list of BMS points.

Alarms

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.

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 preprogrammed with easy-to-use menus.

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.

If the unit supply air temperature falls below Supply Air Low Limit for a period of Alarm Delay, the unit will do one of the following based on the Alarm Function.

• Alarm and Open NO3: Sends an alarm and opens NO3 (Unit Start/Stop

command) even if the BMS start/stop command is active.

• Disable: Disables the supply air low limit function.

The purpose of the supply low limit is to protect the building and contents from cold supply air. It is NOT designed to protect the air handling unit.

If the unit does not have cold or hot water coils, it should not need additional protection from freezing. If the unit does have cold or hot water coils, field provided coil freeze protection may be necessary.
