A simple and cost effective solution when alternating or parallel pump control is required. The new G2ASMA20 pump control relay from Tele, simplifies the design of dual pump controls. Pump A and Pump B are toggled upon start-up to ensure even wear on each pump. During peak demand, both pumps can be switched on for parallel operation, including timing offset on both loads to avoid water hammer effects. Controlled via one or two pushbuttons (depending on mode of operation) and can even be set to operate without control, and be triggered by supply voltage alone.
