CONNECT MOBILE APP

Connect Mobile App

The application is designed specifically for Variable Air Volume (VAV) balancing, offering users streamlined access to the IP VAV controller through integrated Bluetooth technology. By utilizing Bluetooth Low Energy (BLE), the app enables a straightforward connection to the controller and facilitates the discovery of other controllers within the same BACnet™ network, as the Bluetooth-enabled controller serves as a router to this network.

Key features include:

• Users can connect to the controller via Bluetooth ?.
• Single and Multi Controller balancing capabilities.
• Precise calibration of zero velocity cutoff.
• Manual calibration for accurate VAV operation.
• Adjust damper settings for position and airflow.
• Resume normal operation and clear adjustments.
• Generate shareable reports for improved efficiency and documentation in VAV system management.

The app is available for download from the App Store and Google Play.

System Overview

The system overview outlines a four-step process for using the Connect Mobile App:

1. Configure the Controller: A diagram shows a laptop connected to VAV controllers via a network.
2. Connect via BLE: A mobile app screen displays "Scanning for Bluetooth devices...".
3. Balance the Controller: A mobile app screen shows controller details like model, security pin, and Bluetooth connection status, with options to "BALANCE THIS CONTROLLER", "VIEW CONTROLLER", and "DISCOVER NETWORK CONTROLLERS".
4. Generate Report: A mobile app screen displays report information with fields for "Report name" and "Description", and a "GENERATE REPORT" button.

Connect To VAV Controllers

Connect the mobile device to VAV controllers to access their functions. The configured device name will be displayed in the list of BLE devices, organized by signal strength.

A mobile app screen shows "CONNECT VIA BLUETOOTH" with "2 devices found" and a list of "Saved Devices" and "Other Devices", each with a signal strength indicator. Options include "RESCAN" and "NEED HELP?".

Note: Ensure the Mobile Device and the controller are within the BLE range (20-30 meters). Due to BLE advertisement character limitation, only the first 21 characters of Device name will be displayed in the list.

Single Controller Balancing

This method refers to the process of calibrating and adjusting the airflow for one specific VAV controller. It is typically used when a precise adjustment is needed for individual units.

The process involves:

• Select Controller
• Connect to Controller
• Enter Parameters
• Start Balancing
• Review Results

A mobile app screen shows "DEVICE 2222" with status indicators "Zeroed" and "Balanced", controller details, and an option to "Select Balance This Controller option."

Note: If a controller is already balanced, you can choose to clear before rebalancing. Non-Alerton controllers support 2 calibration types – Flow Calibration factor (default 1) & Manufacturer K factor.

Multiple Controller Balancing

This method allows users to adjust and calibrate several VAV controllers simultaneously. It is efficient for operations requiring mass updates or inspections. A maximum of 5 devices are supported for multi-controller balancing.

The process involves:

• Select Controllers
• Input Common Parameters
• Initiate the Balancing Process
• Monitoring Progress
• Review Results for Each Controller

Filter Properties are available:

• Unbalanced: Displays only the unbalanced controllers.
• Balanced: Displays only the balanced controllers.
• Zeroed: Displays only the zeroed controllers.
• Not Zeroed: Displays only the controllers which are not zeroed.

A mobile app screen shows a "NETWORK CONTROLLERS" list with checkboxes for multiple controllers, their status (Unbalanced, Not Zeroed, Balanced), and model information. Users can select controllers and then "GO TO TASKS" or "GENERATE REPORT".

Select "Go To Tasks" and perform the operations on the selected controllers. For more details refer to Clear Zero And Balance, Resume To Normal.

View Controller

Choose the 'View Controller' option to view or update controller properties and settings.

Select the 'View Controller' option and view or update the controller by following operations:

• Balance: Fine-tune airflow for effective system performance.
• Move: Manually reposition dampers for optimization.
• Properties: View Controller Properties.
• Fan: Control Fan settings during balancing.
• Heat: Control Heat settings during balancing.

A mobile app screen shows "DEVICE 2222" with status indicators "Not Zeroed" and "Unbalanced", controller details, and the "VIEW CONTROLLER" option.

Move Damper Operation

Move Damper Operation is a feature that allows users to adjust the position of VAV (Variable Air Volume) dampers. This helps in redistributing airflow within a duct system, which is crucial for optimizing HVAC system performance and ensuring effective climate control.

Move Damper by Airflow: This allows users to command/set the damper to a specific target airflow.

Move Damper by Position: This allows the user to set the damper to a specific position based on a percentage.

A mobile app screen displays current sensed airflow (168 cfm) and current damper position (%). Options include "Move Damper By" with "DAMPER POSITION" and "AIRFLOW" tabs. Users can select "Full open" (100%) or "Full close" (0%) and set "Airflow Tolerance" before pressing "MOVE".

Zero Calibration

Zero Calibration option is critical for maintaining the accuracy and efficiency of VAV controller operations, allowing users to manage calibrations and settings effectively.

A mobile app screen shows "ZERO FOR CALIBRATION" with steps: Edit, Method, Calibrate, Zero. It displays controller details (GA1_01VB107), current sensed airflow (168 cfm), current damper position (50.2 %), and Flow Calibration settings (K factor: 0.95, Zero cutoff velocity: 3 %).

A prompt asks to "ZERO to physically close the damper and adjust the Zero velocity cut off %." with "YES" and "SKIP" buttons.

Tips: It is recommended to set zero cut off velocity by physically closing the damper.

Clear Zero And Balance, Resume To Normal

Perform resume to normal, clear zero, or balancing options for one or more controllers.

Resume to Normal: It will clear any overrides performed during the balancing process.

Clear Zero and Balance: It clears both zero cut off velocity and balancing calibration factor.

Clear Zero: It clears the zero cut off velocity.

A mobile app screen shows a "NETWORK CONTROLLERS" list and a context menu with options: "Balancing", "Zero calibration", "Move", "Unlock damper", "Resume to normal", "Clear zero and balance", "Clear zero", and "CANCEL".

Generate Report

Generate a report by selecting the controllers you want to include. A .csv file will be generated and stored locally in your app.

Give a Name and Description to your report.

A mobile app screen shows "Report Information" with fields for "Report name" (e.g., OrionL1EastWing-2021-07-21) and "Description" (e.g., simple description of the checkout controllers), and a "GENERATE REPORT" button.

Note: Controller connectivity is needed only to generate the report. However, once generated, the reports can be accessed from the Hamburger menu at any time, even without needing to connect to the controller.

View Report

The report will include Balancing status at controller levels, allowing you to Share it with your team.

A tabular "BALANCING REPORT" is displayed on various devices (laptop, tablet, smartphone), showing data points related to balancing status, damper position, airflow, and calibration factors.

Alerton Standard Applications - Point Mapping

Refer to the BACnet points used in Alerton Standard applications during the balancing process.

Note: Please refer to the Controller IOG documentation for guidance on using custom objects for balancing.
