If I purchase two VAV controllers from two different manufacturers, but both conforming to the 8010 profile, does this mean they will behave the same? I.e does the 8010 conformance extend to the logic of how the controller operates or is it simply defining what information can/is to be shared?
I am working on a project where the consultant has specified that the VAVs must conform to Lonmark profile 8010; but they have then specified a fairly non-standard control logic for the operation of the parallel fan and electric reheat (in particular, ramping the primary airflow down from minimum to 0 L/s AFTER the terminal load reaches 0, i.e. while in deadband, and at the same time ramping the parallel fan speed up)
I know the ASC VAV that I have conforms to 8010 but there is no way I can make it do the tricks they want; hence my question.
