Using ON/OFF Control
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

Using PID Control
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.
Step 1 Determining the Control Method

The manipulated variable

The manipulated variable

Direct Operation
The manipulated variable

The manipulated variable
decreases if the temperature is
lower than the set point.
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.
