PID - Reverse Acting


Convert microblock

PID (Proportional, Integral, Derivative) loops use industry standard algorithms to calculate an appropriate response for controlling a physical output, based on the equipment's setpoint and the actual temperature.

The PID - Reverse Acting microblock calculates three values: a proportional value, integral value, and derivative value. These three values, together with the bias, create an output percentage that increases as the temperature falls below the setpoint.
