Have recently moved in to a small cottage which has an oil fired Termecon 40/60 wall mounted external boiler.
The problem is even when the timer is in the off position the boiler is still kicking in which is obviously going to be using excessive oil and isn't correct.
The controls are Siemens RWB9 and I have checked the position of the dip switches and it is set correctly for:-
Daily with 2 on/off switching per 24 hr period
16 mode (fully pumped HW & CH).
The timer appears to working correctly and is coming on and off to the times set but the boiler will still run.
There is no thermostat in the house, the water tank has an external stat and the rads are all individually thermostatically controlled, maybe this is the problem?
Any ideas would be much appreciated before I call in a specialist.
