So does mine. Is yours a gravity fed system? This would be why. I have to turn all my rads off individually so the house doesnt get too hot.
If you have another sort of system then there is probably something wrong with the programmer.

I would say that the motorised valve that switches between Hot Water, Central heating or Both, is stuck...
You'll probably find it near the cylinder (airing cupboard)
Its a box with 3 pipes and I think it has an indicator on it to show the position of the gate.

Get a plumber out if your not sure.

This sometimes happens with our system. It's caused by the valves sticking open on the separate CH and HW systems with a shared pump. You could get a plumber in to fix this but that will cost you a lot for something that can be easy to fix.
The valves are supposed to be opened by a small 'synchron' motor and closed by a strong spring. To free up the valves on our system you need to remove the motors - having disconnected electricity first of course. Also, be careful of small screws as they can easily get lost through gaps in floorboards! After the motors are off I attach lockable pliers to the valve spindles and just jiggle them back and forth for a couple of minutes until they free up. Then replace the motors.
The motors themselves will burn out eventually with sticky valves and they are quite easy to replace - again much cheaper to do it yourself. I was charged £90 by a plumber last time when the motors cost £15 each at the local plumber supplies shop.

If it was working properly before, then it can only be the motorised valve stuck open, or a faulty switch on CH in the programmer. You could have a 2 or 3 port valve.

make sure the bladder in your expansion tank is working properly. Another easy trick is to go to the highest point (radiator) in the system and bleed the air out. If the bladder was stuck you may be getting hydrolocked. If the bladder has a hole in it, you will see residual amounts of air alot. Good Luck!
BTW - there was a recent article about this on This Old House, try checking out there website.

if you have a wall mounted setting for the central heating the timer needs reset to stay off while you use the hot water only . if you have a combi boiler then inside the front panel there is a diagrame to show you how to have hiot water only and its a matter of switchign it over so the heating stays off untill you want it on

That's normal but if you don't want hot water switch the electricity supply off to the boiler.

Check the user manual, surely you can set them both up seperately?
