• This parameter selects 2-PID control or ON/OFF control.
• The auto-tuning and self-tuning functions can be used in 2-PID control.
Setting range
pid: 2-PID, onof: ON/OFF

• This parameter selects standard control or heating/cooling control.
• When heating/cooling control is selected for the E5CN-H (for a model
which does not support control output 2), the auxiliary output 2 terminal
(SUB2) is assigned as the control output (cooling).
Setting range
stnd: Standard, h-c: Heating/cooling

• The ST (self-tuning) function executes tuning from the start of program
execution to calculate PID constants matched to the control target. When
the ST function is in operation, be sure to turn ON the power supply of the
load connected to the control output simultaneously with or before starting
Controller operation.
