In On/Off temperature control, there are two parameters that have a significant effect on the control
characteristics, namely deadband and hysteresis. These need to be addressed in the control menu but a
brief description might help explain the differences.
Deadband - In On/Off temperature control, it is the band above or below the setpoint where there is no
output action. It has the effect of moving the apparent setpoint.
Hysteresis - In On/Off temperature control, hysteresis represents the band where the output changes state
from deactivated to activated. It prevents chattering around the setpoint and prevents rapid output cycling.
