# .BuildSysPro.IBPSA.Obsolete.Controls.Continuous.Examples.PIDHysteresisTimer

Example model for PID controller with hysteresis and timer

## Information

Example that demonstrates the use of the PID controller with hysteresis and off timer. The example is identical to IBPSA.Obsolete.Controls.Continuous.Examples.PIDHysteresis, except that the controller also has an off timer. This timer keeps the control signal at y=0 for a period of `minOffTime=1000` seconds. This may be used to avoid short-cycling if the load is small and the system has little heat capacity.

The figure below shows the control error `con.feeBac.y` and the control signal `con.y`.
