Automatic inverter for 2 pums equipped with 2 inputs for pressure switches and 2 exits for the start of the pumps, it alternates the functioning depending on the pressure switches requests.
In case of simultaneous functioning, it introduces a 3 seconds delay between the start of the pumps in order not to overload the power supply system. The phase shift between the starts and the forced march allow the pumps to avoid any damage caused by the continuous starts in case of damaged expansion vessels.
