Control Panel Features
The Bypass Eliminator 24
™
(Model BPE24) Control is an
interface between a ZONEFIRST Zone Control Panel and its
zone dampers. The BPE24 is used to eliminate the need for
a traditional separate by-pass duct and damper directed
back into the return duct. The BPE24 can ONLY be used
with 24V Power Open/Power Closed Dampers and control
panels.
The BPE24 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 BPE24
and not the zone control panel. The BPE24 has 4 zone
inputs where the damper outputs of the zone control panel
will plug-in on the BPE24. The zone control panel controls
the zone dampers through the BPE24.
The BPE24 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.
INSTALLATION
The BPE24 can be mounted against flush surface and should
be located within 10’ of where the pressure sensor tube is
placed in the duct. Ideally if mounted next to the zone
control panel this will minimize the length of wires for the
interconnection of the panels for the zone dampers.
It is recommended that the panel be mounted to a wall or
return plenum and NOT on the furnace or plenum where it
will be in contact with the high heating temperatures. The
panel can be located in an attic space or in an enclosed
cabinet of a rooftop unit, provided the panel is enclosed and
not in direct exposure to the elements.
