Pelican TC Series - Variable Air Volume with Fan Powered Boxes (FPTB-VAV)

Fan Powered Boxs
Fan Powered Boxes are typically ducted to a single air
handler, similar to the Variable Temperature and Air
Volume (VVT) or Variable Air Volume (VAV) systems.
The primary difference is that some or all zones have a
local fan enabled by the Pelican thermostat.
There are two types of fan-powered boxes:
◦ Series Fan Powered: The fan operates during
heating, cooling, and ventilation cycles.
◦
◦ Parallel Fan Powered: The fan operates only
during reheat cycles.
Each Pelican zone thermostat communicates with the
zone coordinator over the Pelican wireless mesh
network.
Requirements for this Installation
The installation requirements are the same as for VVT
or VAV systems.
For detailed wiring instructions for the zone
thermostat and accessories to each control point, refer
to the wiring diagrams starting on page 18 of this
installation manual.
