To execute ON/OFF control, set the Set Point, PID ON/OFF, and Hysteresis
parameters.
Confirm that the PID ON/OFF parameter is set to onof in the initial setting
level.
1. Press the O Key for at least three seconds to move from the operation
level to the initial setting level.
2. The Input Type parameter is displayed in the initial setting level.
3. Select the PID ON/OFF parameter by pressing the M Key.
4. Check that the set value is onof (i.e., the default).
5. To return to the operation level, press the O Key for at least one second.
Next, set the set point value.
In this example, the set point is set to 200. The set value (i.e., the SP) is
shown at the bottom of the display.
1. Select the Process Value/Set Point parameter in the operation level.
2. Use the U and D Keys to set the SP. (In this example, it is set to 200.)
The new set value can be saved by pressing the M Key, or it will go into
effect after two seconds have elapsed.
Next, set the hysteresis.
