    I am looking for a professional who can develop a controller for a 24V DC VSD pump and a 24V AC (0-10V) mixing valve. This setup requires an analog voltage control interface (0-10V). The contractor needs to have: - Experience with control system design, particularly with mechanical systems. - Understanding of analog voltage control. - Hands-on experience with the specified pump and valve models. Technical knowledge of these components is key. This project will entail interfacing control systems with the selected hydronic pump and mixing valve models. Prior experience with similar projects is a plus.
