I was out a lot of today. I did not alter the heating schedule but when I came back all rooms were showing they were set to 5C apart from one which correctly showed its set temperature. On the main screen each room showed the current temperature but with a small symbol in the bottom right corner depicting a sun and a thermometer partly overlapping the sun. Opening the room to check its setting it should it was set to 5C. Not my doing. By using a custom control to switch the whole system off, waiting a few seconds and then cancelling the setting, it came right but I had to do it a few times as only a few rooms at a time reset. Two refused to and I set an override for a short period to do the same job. Anybody know what the icon is meant to show or what could have caused this? I have not seen this icon/image before.
