Venturi air valves equipped with a UVM work with virtually any BAS controller. UVM equipped valves all use 0 V to 10 V signals from the controller and translates these signals into a pre-determined flow position or percentage position for any valve. For example, a valve with a UVM, that is scaled for 2500 CFM max flow only opens at 1250 CFM if voltage sent from the controller to the UVM is at 5 V, or 50%. The UVM can also produce a 0 V to 10 V output signal as feedback of the valve CFM or valve position.
The UVM board has an eight-position DIP switch and enables you to set a hardware address between 0 and 15, the selection of percentage or CFM input interpretation, the percentage or CFM representation of the output signal, and normal or reverse operation. 15 is normally used as the parent address. Contact the factory before making any adjustments to these DIP switches as they come pre-configured from the factory for most applications.
