Use the VAV PID page to configure VAV PID values.
VAV II application PID settings.
Proportional-Integral-Derivative (PID) values regulate an analog output based on two analog values (one is a controlled variable; the other, a reference variable) and operating parameters. The controlled variable is the variable that should be held constant, for example, a room temperature. The reference variable is the prescribed changeable value of the controlled variable, for example, room temperature setpoint. Define PID (Proportional Integral Derivative) parameters for a VAV II Controller.
Configuration can be performed with the device On-line or Off-line.

| Cooling | |
| Throttling Range | Value ranges from 2 through 30 Deg.F (-17 through 1 Deg.C). The Proportional gain value is equivalent to the throttling range. |
| Integral Action | Value ranges from 0 through 5,000 sec |
| Derivative Action | Value ranges from 0-255 sec. |
