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 20 for more information.
About this task
- Ensure the Use Press Sens as DP check box is not selected. The UVM is not designed to autonomously control a VAV box.
- 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.
- 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.
- To observe dynamic pressure, velocity, and flow values, select the Dynamic Values Tab.
