DEADBAND
Deadband is a zone in which neither heating nor cooling control is performed.
Negative value setting means both heating and cooling control is performed in the zone.
The figure below shows an example of ON/OFF control with the deadband set to 10°C.
At PID control, deadband is enabled for P control. At P control (I = 0 and D = 0.0), with continuous value control, a zone in
which both heating MV and cooling MV equal 0 is formed at
±
5°C of the SP when the deadband is set to 10°C. With the set
-
ting to -10°C, the zone is with both heating MV and cooling MV.
Note: In order to be intelligible, the graphs show MV at P control. However, in case that I and/or D are set, the graphs may
be different from the avobe, since switching of heating MV / cooling MV does not match SP.
