Low Cost Building Automation System Recommendation

Low Cost Building Automation System Recommendation

Low Cost Building Automation System Recommendation

(OP)
I am sure that everyone has their favorite, but I would like some opinions or advice about simple, low cost building automation.  I am in the process of specifying a few systems and my applications are typically single/multizone AHU's equipped with constant flow chiller plants, packaged DX cooling units of varying size.  Anyhow, the main thing that I would like to do is basic scheduling, possibly demand ventilation control, un-occupied temp space temp reset, etc.  I also need the capability to overide for after hours working.  

I want to keep the system simple but extensible, if that makes sense just in case money falls from the sky and I can install a central EMCS monitoring center.  I have hear much about Lonworks and Bacnet compatibility, so maybe some vendor suggestions that can provide low cost solutions.  I don't need a Cadillac, just a reliable, simple product. Please go easy because I don't have much experience with Building Automation.

Thanks In Advance For Advice Suggestions

RE: Low Cost Building Automation System Recommendation

Wattmaster makes a cheap system.  I think the line is called orion controls.  I've used it one one job (with an aaon rooftop and VAV's).  i havent gotten any complaints about it.  I dont know what else that offer besides rooftop and vav control.  Might be worth some research.
