VAV14-IP Software User Manual

Introduction

The VAV14-IP is a configurable and freely programmable controller with BACnet IP, BACnet MS/TP, Modbus TCP/IP, and Modbus RTU protocols onboard. It is delivered with a built-in application, which supports the most popular types of VAV boxes. The possibility of creating a tailor-made application with the power and flexibility offered by the nano EDGE ENGINE makes the controller useful not only for typical VAV boxes but for all types, even the most advanced ones. The VAV14-IP controllers are developed on the nano EDGE ENGINE software platform, which offers cloud connectivity, real-time programming, and automatic exposure of Data Points. This enables a seamless integration with BMS. The platform supports remote control, real-time monitoring, and data analysis, enhancing energy consumption tracking, system performance, and maintenance needs.

Revision History

VAV14-IP Controller

The VAV14-IP is a controller designed for energy-efficient airflow control in HVAC systems. It is equipped with a built-in configurable application and at the same time it can be freely programmable thanks to the versatility of its software platform, the nano EDGE ENGINE, which allows to adapt the controller’s operation to the most advanced systems and equipment.

The controller is equipped with:

• inputs and outputs (4 universal inputs, 2 digital inputs, 3 analog outputs, and 4 triac outputs);

• COM1 RS485 port (with RJ45 and screw connectors);

• ETH1 Ethernet port with 2 fail-safe protected switches (RJ45);

• USB1 port (USB type C for 5 V power supply and device connection in iC Tool);

• SD card for the nano EDGE ENGINE software platform;

• damper actuator powered from the controller;

• 3 DIP switches,

• LED diodes;

• 2 spigots.

Software Requirements

The VAV14-IP controller if developed for the nano EDGE ENGINE software platform. The controller requires at least the nano EDGE ENGINE OS V1.7.0 to operate; it has a built-in mechanism preventing from downgrading the OS version below V1.7.0.

Tools

The VAV14-IP controller can act either as a configurable device, which operation is based on the default pre-loaded application or as a freely-programmable device, which can be programmed to operate on most advanced VAV installations. For both these ends, there are relevant tools designed to configure or program the device.

Tools that enable configuration of the default application are:

• S3 DIP switch;

• iSMA Configurator;

• Control Point VAV panel;

• iC Device Manager (Niagara module);

• iC Tool (using components from the dedicated libraries)

• BACnet objects/Modbus registers (using dedicated objects/registers).

Configuration of the VAV Application

To configure the default VAV application, choose a most suited tool and follow the instructions contained in this manual (see the table below).

Balancing

VAV (Variable Air Volume) balancing is the process of ensuring that a building’s HVAC system delivers the right amount of air to different spaces. The idea of balancing is to find the most optimal operating point of the ventilation system. Proper balancing provides:

• energy efficiency: minimum consumption of electricity, heating and cooling;

• user comfort: temperature comfort, noise, air quality.

Balancing Tools

Tools that enable carrying out balancing actions are:

• iSMA Configurator;

• Control Point VAV panel;

• iC Device Manager (Niagara module).

Freely-programmable Controller

Tools that enable free programming of a user application are:

• iC Tool (using components from the dedicated libraries);

• Workbench (using the Niagara nE2 Link module).
