Rockwell Automation 900-TC32 Digital Temperature Controllers, Series B - Manual (Page 283)

Publication 900-UM007D-EN-E - January 2011
Parameter Functions & Definitions 5-55
PID ON/OFF
Function: This parameter allows you to configure the controller for either the
2-PID control or ON/OFF control method.
The Auto-Tuning (AT) and Self-Tuning (ST) parameter functions can only be
used in the 2-PID control method.
Related Parameters
Refer to the Advanced Setting function group:
• AT Execute/Cancel (page 5-25), Manual Reset, Hysteresis heating,
Hysteresis cooling (page 5-38)
• ST Stable Range (page 5-75)
Standard or Heating/Cooling
Function: This parameter allows you to configure the controller for the
standard control mode or heating and cooling control mode.
When using a 900-TC8X in the heating and cooling control mode, the
Auxiliary Output 3 terminal (SUB3) is typically (default) used for cooling
Control Output functions.
When using a 900-TC16X in the heating and cooling control mode, the
Auxiliary Output 2 output terminal (SUB2) is typically (default) used for
cooling Control Output functions.
When heating/cooling control is selected for the 900-TC32, the auxiliary
output 1 terminal (SUB1) is assigned as the controloutput (cooling).
