Comparator/2 Points Regulator
The Comparator node accepts numeric values for Input 1 connector and Input 2 connector and generates a pulse as the result of the comparison between the two inputs. If the difference between the two input values is greater than the value specified in the Threshold for ON property of the node, a logic 1 is sent to the Output connector. Instead, if the difference is lower than the value specified in the Threshold for OFF property, a logic 0 is sent to the Output connector.
When the the difference is among the two threshold values, the previous state of the output is maintained.
This node is really useful for temperature regulation because it acts as a 2 Points Regulator, preventing frequent switching of the output.
