ZoneFirst Plug-In-Play 2 or 3 Zone Control Panel with By-Pass Eliminator

FEATURES

The Bypass Eliminator™ (Model BPE) Control is an interface between a ZONEFIRST Zone Control Panel and its zone dampers. The BPE is used to eliminate the need for a traditional separate by-pass duct and damper directed back into the return duct. The BPE can ONLYONLYONLYONLY be used with ZONEFIRST’S Plug-In Zone Dampers and control panels.

The BPE uses an air sensor in the duct system on the supply side and before all zone dampers so it can monitor the systems static pressure, whenever the blower is running. The zone dampers are now wired directly into the BPE and not the zone control panel. The BPE has 4 zone inputs where the damper outputs of the zone control panel will plug-in on the BPE. The zone control panel controls the zone dampers through the BPE.

The BPE will, on an increase in static pressure in the duct system, modulate the closed dampers to gradually open to relieve the air pressure back below the high set-point. When this occurs the zone dampers will stop.
