Hi Everybody,
I posted recently about this. There is a confusing controls issue I know of, and I can't understand it. It involves a quincy air compressor, three Hurst LPW boilers, and many pneumatic actuators and thermostats. Many rooms in the building have no pneumatic pressure, and It's now at the point where the discussion must be made whether to replace everything with electric valves, or keep it pneumatic. Any advice from anyone?

Thanks
