The MP-V uses a digital pressure sensor to measure the air velocity pressure signal from the velocity probe in the inlet of the VAV box. The measured value is used by the controller to position the VAV damper actuator for the required air flow.
This section provides recommendations on wire sizes and lengths for the MP-V controllers.
There are five LEDs on the front panel of the MP Series controller.
The Status LED on the front of the SmartX devices changes color and flashes to indicate the status of the device.
The analog outputs are capable of supporting analog voltage or current point types. Therefore, analog outputs support a wide range of devices, such as actuators.
You move the two damper shaft mounting screws to the alternative positions for short shafts only to be able to install the MP-V over a damper shaft with an exposed length that is less than 54 mm (2.125 inches) but greater than 22.2 mm (0.875 inch).
One of the cornerstones of the EcoStruxure BMS is support for open standards. As a result, the MP Series controller complies with the BACnet open standard, one of the most popular standards for buildings.
The MP-V has an integrated damper actuator, which allows for simplified installation of MP-V directly over the damper shaft.
You install the MP-V directly over the VAV damper shaft for damper positioning control and air flow sensing. When you install the MP-V on a damper that rotates counter-clockwise (CCW) to open, use WorkStation or the eCommission SmartX Controllers mobile application to ensure that the configured direction of the actuator rotation matches the damper type.
