It is but we disabled that as my parter's work schedule varies day by day and week by week so that wasn't practical.
Also even when we were using that function the display would still show up orange to show central heating was on. This does not.
The radiators get hot even when the Nest isn't calling for heat. I've kept an eye on it for the last few days and it seems pretty random but I've also noticed it when the hot water has been running, the boiler kicks in and then the radiators start to heat up.
The display shows a C and the burner light is illuminated. And that's what it is normally like when the central heating is on.
I've turned up the thermostat up to a warmer ambient temperature to avoid is getting too cold in the room to see if it the frost thermostat.
I'm currently experiencing an issue with my boiler/thermostat.
I have an Ideal icos boiler (unsure but model either HE15, HE18 or HE24) and use a Nest thermostat. Over the last few weeks i have started to notice that the boiler is coming on even when the thermostat is turned down to a very low...
