10.3 Air detection and system venting
ALPHA offers a Continuous air detection and venting
feature which means the pump can detect air and push it quickly to
the system vent.
If the pump detects air, it runs a venting sequence which enables
more air to escape compared to letting the pump run at maximum
speed during the entire process.
During system venting, the air is pushed to the system vent.
The function can be enabled in Grundfos GO in the Settings menu.
During the guided setup, you are asked if you want to vent the
pump and system now. This is only a single event, and it will not
enable this function.

10.4 Flow limitation
You can set a minimum and maximum flow rate in Grundfos GO.
A minimum flow limit can be set to prevent the boiler from
overheating. A maximum flow limit can be set to prevent noise in
the system.
10.5 Trend data
In the Trend data menu in Grundfos GO, you can see system data
for the last 10 or 100 on-cycles. An on-cycle is the period from
when the pump turns on until it turns off. If the pump runs
continuously for more than 24 hours, one on-cycle is registered and
a new on-cycle will start even though the pump has not yet turned
off. The 100 cycles view consists of 10 observations where each
observation is the average of 10 on-cycles.
You can see the following data:
• Duration of each on-cycle
• Flow
• Head
• Estimated media temperature.
You can use the trend data for system optimization and fault finding.
10.6 Updating the firmware
1. Make sure your smart device has sufficient power.
2. Make sure your smart device is connected to the internet.
If there is no internet where the pump is installed, go to step 3
and then follow the instructions in Grundfos GO.
3. Connect your product to Grundfos GO if it is not already
connected.
Once connected to Grundfos GO, the app automatically checks
if the product has the latest firmware installed. If a newer
version is available, a red dot in Settings menu will appear in
Grundfos GO with the text Firmware update available.
4. Follow the guide in Grundfos GO to install the firmware update.
