Weather's fairly warm outside, thermostat set to 20C, ambient temp 22C no need for CH to be on ....
I have a Vokera Linea 7, the timer on the boiler is set to "OFF", and yet every few hours (mostly at night) the boiler fires up by itself and all the rads get piping hot and the house really heats up.
I repeat - the Timer is set to "Continuously OFF."
I thought at first this was the "anti stick" function that I'm used to hearing go in the early hours of the morning, but that usually fires the boiler for a few seconds - not continuously for a few hours.
I was at home yesterday, and caught the boiler up to it's tricks during the day ... even though the boiler is set to Off.
I decided to switch off the system by turning the control knob to the middle OFF position, when I did this the boiler carried on running - the LED display goes out, the green light on the front goes out, except that the pump keeps running and the burners are going on full power.
The only thing I could do was to use the isolator switch to cut power to the boiler.
When I switched back on it behaved for 5-6 hours, then started running again even though Timer is Off.
Any ideas what needs replacing javascript:emoticon('')
I have an engineer booked, but I just know they are not going to believe me, and I expect the boiler will not misbehave when the engineer gets here javascript:emoticon('')
