Ideal Classic Standard boiler. LP241 Programmer says that it's swiched off, but the boiler is still heating the house. Thermostat in the hallway set to lowest setting, Frost Thermostat in garage is off, Thermostat on boiler itself is set to 2 ( of 6 ). House is like a sauna. I have to switch the boiler of on the control box on the boiler to stop it.

Sounds like the end switch on the motorised valve is stuck on keeping the boiler on.
