The VR series is a browser accessable, high-efficiency, wet rotor, variable speed, sensorless commercial pump for chilled and hot water applications. The ECM motor provides up to 85% electrical energy savings compared with conventional pumps and its multiple operating modes fit most applications. Web connections are a snap with RJ45 input/output for ease of networking. Simple user interface to enable setting changes on the face of the pump, eliminating the need for laptop setup. Real-time performance readouts for flow, power consumption, speed and head values. Self Sensing Dynamic Auto (factory default), Proportional and Constant Pressure plus Manual Variable Speed modes provide for extremely extensive application flexibility. On board 0-10Vdc two way control adjusts speed or head to meet system demands from external control inputs. ModBus control and performance feedback for advanced building management / building automation Systems. Relay outputs for remote monitoring of pump status and digital inputs for external enable or disabling. Simple Main / Standby and Parallel Pump operation (parallel pumps run together as needed) via standard ethernet cabling
