About this task

You can also use the UVM with a pressure sensor. For more information on how to wire the pressure sensor to the UVM, see Figure 18 for more information.

Procedure

  1. Ensure the Use Press Sens as DP check box is not selected. The UVM is not designed to autonomously control a VAV box.
  2. Position the actuator to match the signal. The UVM accepts a 0 V to 10 V control signal from an OEM controller and interprets this as a 0% to 100% position signal for the actuator.
  3. Ensure the CFM not Pos Output box is not selected. The UVM uses the flow pressure sensor to provide a 0 V to 10 V as 0 to xxx CFM feedback signal. The OEM controller modulates the actuator and monitors the CFM signal to obtain the desired CFM value.
  4. To observe dynamic pressure, velocity, and flow values, select the Dynamic Values Tab.
