Bypass Damper Wiring Diagram
With Integrated Bypass Control
Static Pressure Voltage Chart
Static Pressure Option: The Integrated
Pressure Control Board can be field
configured for specified static pressure using a
multi meter and the static pressure – voltage
chart. (Exhibit A). This chart shows voltage (DC)
to inches of W.C. (static pressure) relationship.
Use a multi meter set on VDC and place the
leads on the “C” terminal and “TP1” (test point
one) next to the potentiometer. The Voltage
reading translates to inches of W.C.

Pressure Controller
Make cool call at the zone thermostat of the
smallest zone.
Verify all zone dampers are closed except for
calling zone.
Verify noise at zone registers is not excessive.
Adjust the Integrated Pressure Control LEFT to
lower noise (airflow) or RIGHT to increase
airflow until too noisy.

Note # 1
: To open all dampers, it may be
necessary to remove Y outputs to unit on the
zone control board and to make full cool calls
on all thermostats. This will modulate dampers
fully open and lock out compressor.
On Zonex Systems use air balance
modes for simplified bypass setup.
