When the cylinder cannot connect to the internet during commissioning, use the Mixergy Gauge to set the heat source manually and verify system readiness.
Steps
- Power up the cylinder and observe the LED self-check on the gauge.
- If no Wi-Fi, hold Boost Up + Down on the gauge to enter heat source selection.
- Cycle through:
- Red: Indirect (boiler)
- Green: Heat Pump
- Blue: Electric (PV or backup)
- Power cycle the cylinder to confirm selection.
- Press Boost to initiate heating; the heating demand LED should activate.
Tip from training: Always check that the correct colour is selected. Once heating demand is seen, commissioning is successfully started even offline.
See 'Introduction to the Gauge' for a walkthrough as part of the Mixergy Training with Roy Fugler series.
