Yesterday I noticed that the radiators were hot even though the danfoss FP715 programmer was in the off mode, the CH pump located in the airing cupboard is also constantly on. To recitfy this I have to swith the boiler off when not needed but if I would like to heat the water up for a bath the radiators get hot again even though the thermostat in the hallway is on 0 plus the CH pump is on regardless of all mentioned?
Central Heating stays on regardless of programme settings?

I have 2 motorised valves, a danfoss which is for CH? and honewell for HW?
Could be either. Are they both in the airing cupboard next to your hw cylinder? if so the hot water one will be connectec to the pipe that enters the hw cylinder about 1/2 way up. The heating one will have apipe that disappears into the floor usually. Replace the ch valve head. Sounds like it has stuck.
I wouldn't rush into replacing the head. First determine whether or not the motor is moving and the actuator actuating.
If they are then the cause could 'simply' be debris on the valve ball/flap, in which the system would need cleaning out, although a new valve body would be a short-term remedy.
