Configuring MP-V Controller Setpoints

You configure the MP-V controller setpoints to set up the parameters by which the controller is flow balanced. These setpoints include the maximum flow setpoint, selected by default, and the intermediate and minimum flow setpoints, which are optional.

Use this workflow to perform flow balance on a single MP-V controller, using the eCommission SmartX Controllers mobile application. Related information can be found in the section after the flowchart.

Start eCommission application

Start the eCommission application and log in as either a Technician or Flow Balancer.

For more information, see Downloading and Starting the eCommission SmartX Controllers Mobile Application .

Start flow balance process

Start the flow balance process for an MP-V controller installed on a VAV unit. The direction of damper rotation is verified automatically during this process.

Configure air balancing setpoints

You configure the MP-V controller setpoints to set up the parameters by which the controller is flow balanced. These setpoints include the maximum flow setpoint, selected by default, and the intermediate and minimum flow setpoints, which are optional.

For more information, see Configuring MP-V Controller Setpoints .

Balance at the selected flow setpoints

Using the eCommission application, you flow balance a VAV unit at each designated setpoint to achieve the desired air flow.

For more information, see Flow Balancing at Maximum, Intermediate, or Minimum Flow Setpoint .

Perform optional tasks as needed

After flow balancing the MP-V controller, you can perform other tasks as needed:

  • Manual checkouts of air flow

    After completing the automated flow balancing process, you can optionally verify and command the air flow values by performing manual checkout.

    For more information, see Performing Manual Checkout of Air Flow .

  • Create, append, view, or delete flow balance reports

    After completing flow balancing, you can use the eCommission application to create, append, view, or delete flow balance reports.

    For more information, see Managing Flow Balance Reports .

  • Capture device information from the controller

    You can use the Controller List Creator function of the eCommission application to capture device information from the Digital Matrix symbol on the tear-off product info labels of SmartX IP controllers.

    For more information, see Using Controller List Creator .

To configure MP-V controller setpoints
  1. In the eCommission application, in the main menu of the Air Balancing view, tap Setpoints .

  2. In the Air Balancing Setpoints view, for the Direction of rotation to open , tap either CW or CCW to select either clockwise or counterclockwise rotation.

  3. For Measurement system , tap the current setting.

  4. In the Measurement System dialog box, tap either US or Metric .

  5. In the Flow tolerance box, type the tolerance, in %, associated with the Maximum flow , Intermediate flow , and Minimum flow values.

  6. In the Flow at 1 in H 2 0 or 249 Pa box, type the rated flow of the terminal box at 1.0 inch water column (249 Pa). This value is commonly read from a chart associated with the flow pickup.

  7. In the Maximum flow box, type the maximum flow setpoint associated with the terminal box.

    Important:

    In the Air Balancing Setpoints view, the Intermediate flow and Minimum flow setpoint check boxes are cleared by default. However, it is recommended that you include either or both these setpoints for flow balancing, in addition to the Maximum flow setpoint. Doing so allows you to achieve greater flow accuracy across the operating flow range of the VAV unit.

  8. For Intermediate flow , type a value in the text box or clear the check box:

    • If this setpoint will be used, type an initial value for the intermediate flow setpoint in the text box.

    • If this setpoint will not be used, clear the check box and then type 0 (zero) in the text box.

  9. For Minimum flow , type a value in the text box or clear the check box:

    • If this setpoint will be used, type an initial value for the intermediate flow setpoint in the text box.

    • If this setpoint will not be used, clear the check box and then type 0 (zero) in the text box.

  10. Tap Next .

The flow balancing setpoints are now configured. Flow balancing at the selected flow setpoints begins automatically.
