SYSTEM PRESSURE SET POINT CONFIGURATION

(SETPOINT) TABLE — See Table 11 for System Pressure

Set Point Configuration table.

Table 11 — System Pressure Set Point Configuration

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.

System Pressure

Setpoint: Display Units in. wg

Default Value 0.50

Display Range 0.10 to 1.80

DUCT SENSOR CONFIGURATION (SEN_SERV)

TABLE — See Table 12 for Duct Sensor Configuration

(SEN_SERV) table.

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.

Auto Pressure

Cal: Default Value Disable

Display Range Enable/Disable

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.

Bypass Err

Damp Pos: Range 0 to100%

Default Value 100%

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: Default Value Enable

Display Range Enable/Disable

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.

Duct Temp

Cal Offset: Display Units F

Default Value 0.0

Display Range –9.9 to 9.9

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.

English

Language: Range No/Yes

Default Value Yes
