Hi i`m having trouble with my cxi . NO matter what the wall timer is set to ,even the off postion the centrel heating kicks in , unless i turn the temp knob to zero. So i`m unable to set a on and off time because as soon as i increase the temp on the control it kicks in straight away, i think something might of gone on the board but i`m not sure, can anyone help. thanks alot paul

Have had the same symptoms once on this boiler and it was a faulty actuator.

i know this might sound daft but is the timer not set to constant. or is there any external controls on the boiler that might be turned on ie frost thermostats etc

so in other words the clock timer is still calling for heat maybe its wired wrong.

If it is a new install check the blue wire on the low voltage is disconnected.If it is not it will by-pass the controls and remain on.it could be a faulty timer, or the 240 volt option board playing up. Have had some with the orange link in the p.c.b left in this will also by-pass all the ext. controls and remain on

Also which i forgot to mention is i replaced a o ring and a small amount of water went near the electric board, i know this is supposed to be a sealed area, but if any water got in could this have caused the problem ??? thanks again

What is a Actuator ??

actuator is the black motor clipped on to the divertor valve which drives a spring loaded pin in to divert flow to the c/h you can unclip it and see if it drives in or out.
