SYSTEM PRESSURE SET POINT CONFIGURATION
(SETPOINT) TABLE — See Table 11 for System Pressure
Set Point Configuration table.
Table 11 — System Pressure Set Point Configuration
DESCRIPTION
System Pressure Setpt
System Pressure Setpt — This variable is used to configure
the supply air static pressure set point that is to be maintained
by the bypass controller. The bypass controller determines the
damper position by comparing the system static pressure to this
set point.
Do not use this set point to raise the static pressure if all
zone damper minimum set points are configured to 0%.
Personal injury and damage to ductwork and equipment
may occur.

TABLE — See Table 12 for Duct Sensor Configuration

Auto Pres Cal — This decision is used to enable the automatic
pressure zero calibration option. This calibration is performed
when the system fan transitions to off and remains off for
5 minutes or when this decision is set to Enable and the calibra-
tion has not been performed for at least 168 running hours
(7 days).
If the decision is set to Enable, the bypass controller will
send a request to the associated master zone controller to turn
the fan off. At the end of the calibration the bypass controller
will signal the master zone controller to return the system fan to
normal operation.
If this decision is set to Disable, the bypass controller will
still be able to calibrate the pressure sensor manually from the
Bypass Controller Commissioning Maintenance Table.

Bypass Err Damp Pos — This decision is used to configure
the position to which the bypass controller will hold its damper
during an error condition associated with the pressure sensor.
During the pressure sensor error condition, the bypass control-
ler will hold the damper position and generate a pressure sensor
failure alarm.
NOTE: If this value is set too low, damage to the system duct-
work could occur with a pressure sensor failure.

Press Sensr Cal Alarm — Use this decision to enable an alarm
if the pressure sensor input voltage fails to decrease to within
the zero tolerance (1.0 ± 0.1 vdc) of the sensor. The alarm is
disabled if this decision is set to Disable.
Press Sensr
Cal Alarm:
Duct Temp Cal Offset — This decision is used to calibrate the
duct temperature sensor by adjusting the offset value to the de-
sired temperature trim value. For example, if the temperature
displayed is two degrees above the value measured with cali-
brated test equipment, input a value of –2.0.

DEVICE CONFIGURATION (BYPASS) TABLE — The De-
vice Configuration table contains reference information about
the bypass controller. The user can input a short description and
the location of the device. The Software Part Number, Model
Number, Serial Number, and Reference Number are also
shown. See Table 13.
LANGUAGE CONFIGURATION (LNGCONF) TABLE —
Use this decision to select the display language that will be seen
on all user interfaces for this controller. By default, the bypass
controller displays information in English. To change to a sec-
ond language display, set this decision to No, download this
table and then upload the bypass controller to see the factory-
loaded second language. If a second language is not available
in this module, this decision will be disregarded and informa-
tion will continue to be displayed in English. See Table 14.
