System Pressure — This variable displays the static system
pressure through an integrated pressure sensor in increments of
0.1 in. wg. When Bypass Commissioning and Pressure Sensor
Cal are
Enabled , the user may force this value to the correct
reading of the System Pressure as measured with calibrated test
equipment. From the forced value, the bypass controller calcu-
lates a calibration multiplier that will always be applied to the
System Pressure sensor reading. Once the multiplier is calcu-
lated, the force is removed and the multiplier is applied to the
System Pressure sensor reading.
System Pressure: Display Units
in. wg
Default Value 0.00
Display Range 0.00 to 2.00
Forcible Yes
System Pressure Setpt — This variable displays the supply air
static pressure set point that is to be maintained by the bypass
controller. The bypass controller determines the damper posi-
tion by comparing the system static pressure to this set point.
When the user forces the System Pressure Setpt from this table,
the bypass controller automatically updates the System
Pressure Setpt configuration value in the Pressure Setpoint Ser-
vice Configuration Table.
System Pressure
Setpoint:
Display Units in. wg
Default Value 0.50
Display Range 0.10 to 1.80
Forcible Yes
Damper Cal Alarm — This variable displays Alarm if the
damper calibration process failed because there was an error
during the closed or open position calibration of the damper.
Normal is displayed when a successful damper calibration
takes place.
Damper
Cal Alarm:
Default Value Normal
Display Range Normal/Alarm
Forcible No
Press Sensr Cal Alarm — This variable displays Alarm if the
pressure transducer zero calibration process failed because the
pressure sensor voltage did not decrease to within the zero
pressure tolerance (1.0 ± 0.1 vdc).
Normal will be displayed
when a successful pressure transducer zero calibration takes
place.
Press Sensr
Cal Alarm:
Default Value Normal
Display Range Normal/Alarm
Forcible No
BYPASS CONTROLLER SYSTEM PILOT DEFAULT
MAINTENANCE TABLE — See Table 8 for Bypass Con-
troller System Pilot Default Maintenance (SP_MAINT).
Duct Temperature — This variable displays the duct tempera-
ture at the bypass damper through a 10K thermistor with a
measurement range from –40 to 245 F in 0.1º F increments.
Duct
Temperature:
Display Units F (C)
Default Value –40.0
Display Range –40.0 to 245.0
Forcible Yes
Damper Position — This variable displays the damper posi-
tion percent range of rotation determined by the damper feed-
back potentiometer. The bypass controller is designed for use
on dampers with a range of rotation up to 90 degrees.
Damper
Position:
Display Units % open
Default Value 0
Display Range 0 to 100
Forcible No
System Pressure — This variable displays the static system
pressure through an integrated pressure sensor in increments of
0.1 in. wg.
System Pressure: Display Units in. wg
Default Value 0.00
Display Range 0.00 to 2.00
Forcible No
System Mode — This variable displays the master zone con-
troller’s system mode as the bypass controller’s system mode
except when the bypass controller is in its commissioning
mode or the network communication fails. In bypass commis-
sioning mode, the system mode will display
BPCOMMIS to in-
dicate the bypass controller is in its own commissioning mode.
If the network communication between the bypass controller
and the Linkage Coordinator zone controller fails, the system
mode will display
LOCAL .
System Mode: Display Units ASCII
Display Range HEATING, COOLING,

PRESSURE, EVAC,
ZONE_BAL, OFF,
BPCOMMIS, LOCAL
Forcible No
Configuration Tables —
The bypass controller con-
tains the following configuration tables: Alarm Configuration
(ALMCONF), Bypass Controller Configuration (BP_SERV),
Device Configuration (BYPASS), Language Configuration
(LNGCONF), Duct Sensor Configuration (SEN_SERV), and
Set Point Configuration (SETPOINT).
ALARM CONFIGURATION TABLE — The Alarm Con-
figuration Table (ALMCONF) contains decisions used to con-
figure the alarm settings for the zone controller. This includes
realarm time and routing of alarms. See Table 9.
