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.
