Using ON/OFF Control

The procedure to use ON/OFF control is given step by step in this section.

The default setting is for reverse operation.

For heating control, select reverse operation. For cooling control, select direct operation.

With ON/OFF control, you can adjust the reset width (called the hysteresis) for heating or cooling

operation. The default setting is 1.0°C.

Heating (Reverse) Operation Cooling (Direct) Operation

When the output turns OFF at the set point, the

temperature will decrease. You can set the

temperature width that determines when the

output will turn ON again.

When the output turns OFF at the set point, the

temperature will increase. You can set the

temperature width that determines when the

output will turn ON again.

Using PID Control

3-1

Using PID Control

The procedure to use PID control is given step by step in this section.

The default setting is for reverse operation.

For heating control, select reverse operation. For cooling control, select direct operation.

You can automatically or manually set the PID constants that are used for PID control.

Adjusting the PID Constants

The suitable values of the PID constants that are used for temperature control depend on the

characteristics of the controlled object.

There are three ways that you can use to set the PID constants. These are described

below.

⇒Use autotuning (AT).

⇒Set the PID constants

manually.

⇒Use self-tuning (ST).

1 Select direct or reverse operation.

2 Adjust the PID constants.

If you ca n allow the temperature to vary while tuning the PID

constants and you need to calculate the optimum PID constants:

If you know the PID constants in advance:

If you cannot allow the temperature to vary and you need to

automatically estimate the PID constants when the set point is

changed:

With self-tuning, calculation of the PID constants is affected by

changes in the temperature, such as when a heater is turned

ON and OFF. The PID c onstants will be automatically

calculated and set. If there is an external source that causes

temperature changes (such as a heater turning OFF), u se

autotuning or set the PID constants manually.

* To set these parameters, first set the st (ST) (self-tuning)

parameter in the Initial Setting Level to off (OFF) to

disable self-tuning.
