This parameter selects 2-PID control or ON/OFF control.<br />

The auto-tuning and self-tuning functions can be used in 2-PID control.<br />

Setting range Default<br />

pid: 2-PID, onof: ON/OFF pid<br />

This parameter selects standard control or heating/cooling control.<br />

When heating/cooling control is selected for the E5CN-H (for a model<br />

which does not support control output 2), the auxiliary output 2 terminal<br />

(SUB2) is assigned as the control output (cooling).<br />

Setting range Default<br />

stnd: Standard, h-c: Heating/cooling stnd<br />

The control must be set to a temperature<br />

input, standard control, and 2-<br />

PID control.<br />

The ST (self-tuning) function executes tuning from the start of program<br />

execution to calculate PID constants matched to the control target. When<br />

the ST function is in operation, be sure to turn ON the power supply of the<br />

load connected to the control output simultaneously with or before starting<br />

Controller operation.
