No rain condition: is any period of at least T1 minutes of no precipitation. The beginning of precipitation during the no rain period determines the transition to the status of “first rain”.
First rain condition: rainy condition, following a continuous period of no rain, or interrupted by rain event intervals lower than T2 minutes, until rain volume reaches Qp mm. When reached Qp mm of precipitation the system moves to Further rain condition. If during First rain condition rain stops for a period longer than T2 minutes, the system goes back to the “no rain condition”.

Further rain condition: is the periodo following the first rain condition, during woch there are not rain breaks longer than T1 minutes. Break longer than t1 minutes determines the transition to the “no rain condition”.
T1, T2 e Qp parameters are programmable.
