Reference Section: Programming Mode (PRoG)
Navigate to the desired setting. Settings include the following:
 ACtN – Determines the action direction for control
 dEAd – Sets the deadband value; the deadband value is applied in the
same units as the process variable to one side of Setpoint as determined by
the ActN direction
 S.PNt – Allows either Setpoint 1 or Setpoint 2 to be specified as the
target value; Setpoint 2 can be set to track Setpoint 1 using the deviation
(dEVI) option (7.2 Setpoint 2 (PRoG > SP2))—a useful feature when setting
up for heat/cool operation
Select the indicated setting.
For ACtN, select the correct setting. Settings include the following:
 RVRS – Off when Process Value is > Setpoint, and on when Process Value
is < Setpoint (e.g., heating); deadband is applied below Setpoint (factory
default)
 dRCt – Off when Process Value is < Setpoint, and on when Process Value
is > Setpoint (e.g., cooling); deadband is applied above Setpoint
For dEAd, set the desired value. (The default is 5.0.)
Select the indicated ACtN setting, or confirm the dEAd value.
7.4.1.5 Output as Alarm 1 (PRoG > oUt1–oUt6 > ModE >
ALM.1)
Select this Output to be an Alarm using the Alarm 1 (ALM.1) configuration.
7.4.1.6 Output as Alarm 2 (PRoG > oUt1–oUt6 > ModE >
ALM.2)
Select this Output to be an Alarm using the Alarm 2 (ALM.2) configuration.
7.4.1.7 Retransmission (PRoG > oUt1–oUt6 > ModE >
RtRN)
Select Retransmission (RtRN) as the Operating Mode for the output. This option is
only available for analog outputs. Scaling is performed using absolute values—not
calculated counts. The retransmission signal type (voltage or current and range) is
set for this output using the 7.4.3 Analog Output Range (PRoG > oUt1–oUt6 > RNGE)
parameter. The retransmission signal is then scaled using the following 4
parameters. The unit will display the first scaling parameter, Rd1, after RtRN is
selected.
