On the app, override one zone to 28°C for 1 hour. Ideally choose a room that has only 1 Radiator Valve.
- Click on the zone to override
- Change the mode icon at the top-right to the Override symbol (3 arrows)
- Ensure the override temperature is 28°C and the override duration should be 1 hour
- Check that the boiler Receiver Unit is active:
- A Single Channel Receiver shows a green light.
- Hold down the Heating button on the the Dual Channel Receiver (the light at the top-left with turn green for 2 seconds).
- An Electric Switch shows a red light next to 'HUB'.
- A Single Channel Receiver shows a green light.
- Check the boiler fires as normal and the correct zone valve has opened.
Check that the central heating pipe from the zone valve or boiler gets hot.
Wait 10 minutes, then check the radiator in & out pipes and that each radiator is cold not hot! (Except for the overridden zone).
Info This confirms all the valves are properly seated on the radiators, and they can turn the radiators off.
