Using ON/OFF Control

The procedure to use ON/OFF control is given step by step in this section.
Step 1 Determining the Control Method
Select direct or reverse operation.
1
The default setting is for reverse operation.
For heating control, select reverse operation.
Reverse Operation (Default)
ON
Heating
OFF
Set point
Output turns ON if the
temperature is lower than the
set point.
Adjust the hysteresis.
2
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
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.

Set point
This width can be set as the
hysteresis.
