4.3 Product description
The level-control unit switches the pump on and off according to the
liquid level measured by float switches or a pressure sensor. When
the start level is reached, the pump starts, and when the liquid level
has been lowered to the stop level, the pump is stopped by the
control unit. An alarm is indicated in case of for example high-water
level in the tank or sensor failure.
Basic settings are configured via the operating panel and advanced
settings are configured with Grundfos GO Remote. Furthermore,
you can read important operating parameters with Grundfos GO
Remote.
