I feel like the fan powered (plenum reheat) is less of a thing today honestly. With all LED lighting, there isn't as much heat in the plenum to grab anymore. Honestly, if you can get by with 15% OA on the RTUs, then you don't have high people density, or you aren't doing ventilation calcs correctly. . First cost of electric reheat on boxes is .
Reheat Type: Fan Powered; Fan Control: Series (technical support configuration) The thermostat controls the zone damper, local reheat, and series fan with the following outputs: (Y): 24VAC Output – Damper Open (Y2): 24VAC Output – Damper Close (if an open/closed or floating damper actuator is installed) (W): 24 VAC Output – Reheat EnableSince the primary air is VAV, there is significant fan work savings. Using plenum air for reheat offers additional efficiency. Parallel fan-powered VAV systems are more efficient than series fan-powered VAV because the box fans are used only when required. The following are some considerations outlined in ASHRAE Std. 90.1-2016.
To add - you’d use them in perimeter zones if you have electric reheat at the boxes. Since you need a minimum of 70-75 CFM/kW to keep the electric strip heater from tripping, it’s a good application for parallel fan powered boxes. When you need heat, the fan comes on. When you don’t, the box can go down to the minimum driven by . I udnerstand if there is electric reheat you want to keep air moving across it, but if the boxes are served by a complete conditioning system, what advantage are fan powered boxes?
