Dehumidification uses zone air dewpoint compared to dewpoint setpoint. If the zone is higher, chilled water valve is opened to 100% and the electric heating coil is modulated to reheat the air

How can a multi-zone AHU control to a single zone sensor? Is it actually the return air dewpoint sensor?

I would separate the heating control from here - you can probably use the existing HTSC type
