Heat or Cool Control PB
Set the proportional band (also known as gain). A larger value yields less proportional action for a
given deviation from setpoint.

PB ? 50
Selectable values:
Dependent upon sensor type.
The controller internally represents the proportional band (PB) as a gain value. When you edit the
proportional band, you will see the values change in predefined steps; small steps for narrow
proportional band values and large steps for wide proportional band values.
The controller calculates the default proportional band for each input type according to the following
equation:
Default PB =
(High Range - Low Range)
Gain
Heat or Cool Control TI
Set the integral term (also known as reset). A larger value yields less integral action.

Heat or Cool Control TD
Set the derivative constant. A larger value yields greater derivative action.
