55 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.
