Control Panel 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 ONLY
ONLY
ONLY
ONLY 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.

The BPE 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.
The cover easily removes from the case by pulling firmly and
separating the cover from the case exposing the circuit
board. There are 4 key-hole mounting points in each corner
of the case. The case has openings in the rear of the case
as well as the side for all wiring. Wiring can come from the
back as well as the side in order to make a neat installation.

The BPE includes 10 feet of pressure tubing (which can be
cut down to size), as well as a duct probe, and four 7 foot
telephone cables to interface the BPE with the zone
controller.
