To do that what you need to know is what type of signal it needs to see at the board's input. If your Metasys has a 4 to 20 output with scaling which I believe it does, then it can be converted to any signal that the board wants to see including a resistive value with the addition of another component.
So the short answer is yes you can do it but you need to do a little more research to actually implement it. You can probably get the information you need from carrier as far as what type of signal you will need. My hunch is that its probably just a resistive value as that's the cheapest way to make the board.
Let me be more specific with my question.
The Bryant FV4B has an ECM motor controlled by "Easy Select" taps on a Printed Circuit Board. These taps are supposed to be used by the installer to configure the system. The ECM motor then uses the selected taps to modify its operation to a preprogrammed table of airflows.
Which taps (if any) can I control (from the Metasys) to force the ECM to a slower speed when only one zone of a 2-3 zone system is calling for air? I want to avoid using a bypass damper if I can.
