Using SCALA1 with Grundfos GO

Explore comissioning, monitoring, and advanced customisation options for SCALA1 with the Grundfos GO app.

The Grundfos GO app helps you get the most out of your SCALA1 pumps whether you have a single pump or a twin configuration.

With Grundfos GO, you will experience fast and easy commissioning, improved monitoring and a host of customisation options that can tailor your SCALA1 pumps precisely to your needs.

You can download the Grundfos GO app from the App Store or Google Play.
Once installed you need to pair the app with your SCALA1 pump by pressing the connect button on the pump.

Once paired you can start commissioning the pump.

First, select how the pump is connected.
Is it boosting from city mains, roof tank, tank above ground, well or from some other source?
Next, the app will ask whether or not the pump is set up with an external input source, for instance a high level switch in a roof tank. And if so, what is the default state of the input and how should the external input control the pump?

You can also choose to set the maximum runtime.
By default the feature is disabled. But for security reason you may choose to alter this so that the pump stops and issues an alarm when the maximum runtime is exceeded. You can also change the auto reset of alarms and enable the cycling alarm which will alert you if any small leakages are detected in the system.

Lastly, enter a unique name for the pump. This can be very helpful if you need to distinguish between different pumps in a bigger project.

You will now see a summary of your choices. You can choose to create a report to share with a client or as a backup for your own benefit. You can also choose to go directly to the dashboard.
That’s it – it is in fact that easy to set up a SCALA1 pump with  Grundfos GO. If you on the other hand are commissioning a SCALA1 twin pump there are a few extra decisions to be made.

One is the operation mode. Should it be the default duty stand by, where the secondary pump simply acts as a backup? Or should it be duty assist where the pumps can work together to provide more flow.
Secondly, there is the alternation type. To make sure that both pumps are utilised equally, they switch pritority at regular intervals. You can choose to alternate based on runtime, number of starts or a combination of both. You can then set the exact hours between alternation or set the number of starts between alternation.

Now that we have covered commissioning of both a single SCALA1 pump and a SCALA1 twin configuration, let’s look at how to create a report documenting the work.

Enter title, name and an optional report ID.
Finalize the report by signing it.
Now you can send it to any of your contacts.
The dashboard of SCALA1 provides access to the many features such as:
- Events
- Settings
- Pump operation
- Trend data
- The metrics
- And the scheduling function.

If a warning occurs the event icon displays the number of warnings and beneath you will see a short description. You can open the warning message to get more information.

Another great benefit of  Grundfos GO is trend data.
Here, you can find charts showing runtime, as well as number of starts. You can view all metrics to closely monitor pump performance. If you have a twin pump setup, you can of course see data from both pumps. By default the pump is always on stand-by mode.

However, you may want to schedule a time frame to limit the pumps runtime. If a tap is opened within the scheduled time frame, the pump will not start. This may be relevant if the pump is to be used in irrigation for instance. Use the scheduling option. To set a recurring event by selecting the days of the week on which you want to limit the pumps operation. Then set the schedule start and end time.

We have now covered the main benefits of using the Grundfos GO app with SCALA1 pumps.
