The digital input of the pump (terminal 1, fig. 4) can be set to different functions. • The max. curve can be adjusted within the range from maximum performance (100%) to min. curve. • The min. curve can be adjusted within the range from max. curve to 12% of maximum performance.
Grundfos.bk Page 13 Thursday, November 11, 2010 11:21 PM 7. External setpoint signal 8. Bus signal By connecting an analog signal transmitter to the input for the setpoint signal (terminal 4), it is possible to remote-set the setpoint. The pump enables serial communication via an RS-485 input. The communication is carried out according to the Grundfos bus protocol, GENIbus protocol, and enables connection to a building management system or another external control system.

E-circulator series 2000 Proportional-pressure control: 9.1 Functions The pump head is reduced at falling water demand and increased at rising water demand, see fig. 20. Most functions can be selected by means of the pump control panel. However, some functions can only be selected via the R100 or via bus. Constant-pressure control: The pump maintains a constant pressure, irrespective of water demand, see fig. 20. 9.1.
