19. Setting by means of R100
The pump is designed for wireless communication with Grundfos
remote control R100.
Fig. 27
R100 communicating with the pump via infra-red light
During communication, the R100 must be pointed at the control
panel. When the R100 communicates with the pump, the red
indicator light will flash rapidly. Keep pointing the R100 at the
control panel until the red LED diode stops flashing.
The R100 offers setting and status displays for the pump.
The displays are divided into four parallel menus (see fig.
35
):
0. GENERAL (see operating instructions for the R100)
1. OPERATION
2. STATUS
3. INSTALLATION
