- Graph 1 a pure proportional logic will load or unload with a frequency related to the set point distance 110
- Max pulse period 110
- Min pulse period 110
- Pulse time 110
- Pulse time the time of the pulse time is fixed default 0 s the interval time between two pulses is proportional to the pid proportional integral derivative unit request 110
- Esie07 05 functional control 111
- Graph 2 the derivative part of the logic controls how the temperature reaches the setpoint if it is getting closer increases the time between intervals or if it is far from the setpoint decreases the time between intervals the result is having the controller act differently whenever the water temperature changes 111
- If the derivative time is increased the control will be more sensitive to temperature changes for example the derivative time can be increased when a chiller is working with a very variable load the integral time stores the memory on how the p 1 controls the temperature 111
