On off management 54
Continuous loading and unloading uses 2 solenoid valves to control the screw compressor slide and thus its capacity control is performed by outlet temperature 55

Functional control esie07 05 78
Graph 1 a pure proportional logic will load or unload with a frequency related to the set point distance 78
Max pulse period 78
Min pulse period 78
Pulse time 78
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 78
Esie07 05 functional control 79
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 79
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 79
