FEATURES Brio 2000 is designed to automatize the starting and stopping operations of an electric pump with regard to a drop in pressure (opening of the taps) and to the stopping of the flow through the system (closing of the taps), respectively. Brio 2000 stops the pump when senses the lack of water flow, preventing it from any damaging dry operation.
www.motor-pump-ventilation.com OPERATING INSTRUCTIONS The switch starts up the pump for 15 seconds once connected to the line. Any further pump starting occurs when the pre-set operating pressure value is reached, accordingly to the drop in pressure in the tubing when opening a tap. In the traditional water systems equipped with pressure switch and pressure tank, the pump stops when a certain pressure value is reached.
