What does the dot with a drop symbol in it mean? We never heat the water with the gas central heating as we have solar panels for this purpose. The water heating function on the Nest controller has been turned off
Thanks for reaching out. I understand you're referring to preventing bacteria. I am happy to help you with this. I recommend visiting How the Nest thermostat helps prevent Legionella bacteria. There, you'll find information on how it works and how to activate or deactivate it as you prefer.
I hope this helps! Let me know if you have any other questions.
