Product Details
EV3 can be used in four different applications, making it a truly versatile, fully automatic controller.Used with BESFUL three-wire water-level sensors for fully automatic water filling, pumping from wells to storage tanks, automatic drainage based on reservoir levels, automatic basement flood drainage, temperature-controlled heating with dry-burn protection, and many other applications.DIN rail design for easy installation and maintenance, with simple single-button operation.
Standard DIN rail mounting with a plug-in base for easy replacement; compact design
A manual water supply button allows temporary refilling for easy commissioning and adjustment.
Upper and Lower Limit Liquid Level Control (Purpose 1)
pumping and drainage control (use II)
single level water control (use three)
Water supply and heating anti-dry combustion control (use 4)
