Grundfos Remote Management
Grundfos Remote Management is an easy-to-install,
low-cost solution for wireless monitoring and
management of Grundfos products. GRM is based on
a centrally hosted database and a web server with
wireless data collection via GSM/GPRS modem. The
system only requires an internet connection, a web
browser, a GRM modem and an antenna as well as a
contract with Grundfos allowing you to monitor and
manage Grundfos pump systems.
You have wireless access to your account anywhere
and anytime you have an internet connection, for
example via a smartphone, tablet PC, laptop or
computer. Warnings and alarms can be sent by email
or SMS to your mobile phone or computer.
For information about the CIM communication
interface module and GSM antennas, see Grundfos
Remote Management, page 131.
Digital inputs

or stop or forced maximum or minimum curve.
Note: If no external on and off switch is connected,
maintain the jumper between the Start/Stop (S/S) and
frame ( ) terminals. This connection is the factory
setting.
