Using TUNE at Start-Up for Duplex (Heat/Cool)
Table 4-23 Procedure for Using TUNE at Start-up for Duplex
Step Action
1
Heat Zone:
• Adjust Local Setpoint 1 to a value within the Heat zone.
• Put the controller in Automatic mode.
• Press the Lower Display and ▲ keys simultaneously to initiate Heat tuning.
The output will cycle between 50% and 100% (or high output limit). A large T
appears in the upper display until tuning is completed and final Heat parameters
are entered for PID set 1 in the Tuning group.
2
Cool Zone:
• Adjust Local Setpoint 2 to a value within the Cool zone.
• Put the controller in Automatic mode.
• Press the Lower Display and ▲ keys simultaneously to initiate Cool tuning.
The output will cycle between 0% and 50% (or low output limit). A large T appears
in the upper display until tuning is completed and final Cool parameters are
entered for PID set 2 in the Tuning group.

Table 4-24 Procedure for Using SP Tuning at Start-Up
Step Action
1
Put the controller in manual mode by pressing the MANUAL/AUTO key.
2
Let the PV stabilize.
3
Adjust the setpoint to the desired value.
4
Put the controller in automatic mode by pressing the MANUAL/AUTO key.
The controller will switch to automatic mode and the process will start to move
toward the setpoint and will line out with the proper tuning constants. A large T
appears on the left side of the upper display to indicate that SP tuning is in
progress.
