If BOTH outputs are set to OFF in the Output Type Menu, the controller will function as a non-
controlling indicator. Control outputs will be disabled and the Operating Modes will not be
displayed.
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.
