Combi not stopping on schedule

[jojo77m]

I have a programmable thermostat set with a daily schedule 06:00-09:00 the maximum temperature should be 21c, every radiator in every room has a TRV, this morning the room with the thermostat was at 25c and the radiators in that room (and all the other rooms) were still on and the boiler still heating.
I would think that if the thermostat say's it's reached the max temp it should tell the boiler to stop? is that not correct? (at the very least, the trv in that room should have stopped no?)




thanks

Is it a new stat ?

Is it a new stat ?

we bought the house 3 years ago and it was here when we bought it, I don't know how old it is

Has it ever worked ?

i am assuming that this room stat is wireless - does it need new batteries ?
