P: %
Minimum fresh air damper position during occupied operation. Value
of 101 allows adjustment by potentiometer on economizer board A55
only. When in global mode with A55 EM1 versions 2.01 and earlier,
only 101 should be used.

C:Min.
Start−up demand delay. Holds off all unit operation zone sensor and
CAVB applications. Hold off FAH−Reheat, FAC, FAH options and all
GP outputs.
May be used to stagger unit start−ups. Does NOT delay demands in
thermostat mode.

IAQ_Input_
Source/Mode
0 0 5 Option
IAQ input source and mode (0−3 operate only when blower is on).
0− DCV System IAQ. Either P298−3 or network IAQ.
1− DCV System IAQ. Either P298−3 or network IAQ with no OAT limits.
2− Outdoor Air Control Sensor A24 (A133_P194−6) (TB22−6).
3− Outdoor Air Control Sensor A24 (A133_P194−6) (TB22−6) with no
OAT limits.
4− DCV System IAQ. Either P298−3 or network IAQ with blower on/auto
operation.
5− DCV System IAQ. Either P298−3 or network IAQ with blower on/auto
operation with no OAT limits.

Weight Description
1− IAQ (A63)
2− Zone Temp. (A2)
4− Outdoor Enthalpy (A7)
8− Indoor RH (A91)
Option is sum of the weights for all input signals that are provided
remotely over the network.
Note: When network sensor is used the physical analog input is ig-
nored. Loss of sensor alarms will not occur unless network commu-
nication is lost for 5 minutes, or has not been established within 5
minutes after reset.
