Understanding the SCALA1 pressure booster

Get a brief introduction to the SCALA1 pressure booster and an understanding of the pump's operating panel.

If you’re looking for an all-in-one pressure booster, the Grundfos SCALA1 may be the answer to your questions.

In this module, we’re going to briefly introduce you to SCALA1 before providing you with a thorough understanding of the pump’s operating panel.

Let’s get started.

SCALA1 is a fully integrated, self-priming pressure booster built for domestic applications.

It gathers all the components of a modern pressure booster into one compact unit.

Furthermore, its Bluetooth compatibility enables connection to the Grundfos GO Remote app, giving even more customisation possibilities and advanced features.

You can also add an external 24V digital input as an extra condition for pump control.

This means that you can add a level switch in a roof tank, for instance. 

Or if you’re using the pump for domestic irrigation, you can add a moisture detection switch telling the pump to stop if the required moisture level is met. 

An external input is simply a means to give you more control.

Finally, SCALA1 offers twin pump configuration, meaning that two SCALA1 pumps can be connected to work in unison, either in duty/standby mode for safety reasons, or in duty/assist mode if you want to increase boosting capacity.

Now that we’ve covered the basic advantages of SCALA1, let’s turn our attention to its operating panel.

SCALA1 shares the same familiar look as its sibling, SCALA2, offering an intuitive, easy-to-use operating panel.

Arguably, the most important icon here is the Grundfos Eye, which shows the pump’s status. 

Static green means that the power is on, but the motor is not running, because there is no demand.

Rotating green means that the power is on and the motor is running, because a tap is open somewhere in the installation.

Yellow means that the pump has been stopped either by means of an external input or a calendar function, or that the twin communication has been disrupted.

Finally, the red alarm means that the motor has stopped. The pump stops automatically, protecting both itself and the installation against damage such as dry running.

You can find out more about these different signals and what they mean in the GO Remote app or in the SCALA1 instruction and operating manual.

In terms of physical buttons, there are just three:

the stop toggle button which stops the pump,

the connect button which is used when pairing a pump with the GO Remote App,

and the reset button which is used to reset alarms. 

The bottom three LED icons on the operating panel are the three system alarm indications. 

These alarms indicate if there is dry running or water shortage, 

if the maximum runtime has been exceeded, 

or if there is a leakage in the system. 

That covers our basic introduction to SCALA1 and its operating panel.
