Unknown symbol on Nest thermostat

[AlistairL]

Good afternoon folks, I have noticed from time to time I have an icon I don’t recognise on my Nest thermostat. It’s a yellow circle with a black teardrop. It’s in the same place as the green leaf would live. Strange thing is it comes on when the heating is generally off. Sometimes in the middle of the night the pump is running but nothing else is happening. The heating is off but I’ve got this symbol. 

Ideas anyone? Is it a fault somewhere?

Best regards

Hey there,

I wanted to follow up and see if I could be of any help. This icon is displayed on the temperature screen whenever your Nest thermostat is using your system to adjust the humidity in your home. This icon will only appear if you have a humidifier or dehumidifier installed on your thermostat. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further. 

Best regards,
Jake
