After testing the Water Pump it was found uncessery to create a PID controller, since the pump is not that powerful. This means that the pump function block only needs to be a simple on or off function block. Additionally to give CDP the option to override the pump there is a override input. The override input takes in three values; 0, 1 and 2. The following table describes the function for these values.

Then there is two outputs, one boolean to start or stop the motor and one to tell CPD the state of the motor, the states are shown in the table below
