Grundfos SCALA1 3-45 User Manual

9.2.1.2 Roof tank filling
In the installation below, the level switch is used to
signal the pump to run when the water level in the
tank drops.
The example below shows the float switch in the input
closed position. In this case, the pump should not run,
and Grundfos GO Remote settings indicate that the
input is closed.
If you exceed the maximum tapping point of the
pump, the external input should run on input only.

9.2.2 Calendar function
The operation of SCALA1 can be scheduled in the
calendar function of the Grundfos GO Remote app.
This function determines when the pump is allowed to
run and when not. It is particularly beneficial for
irrigation and agriculture purposes, where the pump
should be active only within a certain period of time.

app and follow these steps:

When the pump has been stopped by the
calendar function, it will be indicated on
the HMI by a steady yellow Grundfos Eye.
