    I have a iIdeal logic combi 24 with prt2 thermostat.
    I've broken the thermostat and now it will not communicate with the boiler.
    How do I start the heating without the thermostat. The house is freezing and my pregnant wife is about to murder me.

    Hi - sorry to hear about your troubles !
    There are live wires inside the stat, so unless you're confident with safe isolation its dangerous to open it up.

    If you are confident with wiring then simply put a link between the terminals inside the prt2 to bypass the stat. Do I need to say turn the electric off first and then double check there is no power to it before you do anything.

    Have you got the left hand part fitted into the boiler?

    Thanks for the replies.
    I've managed to rebuild the thermostat and cowboy a fix on the PCB to get it transmitting again. The timer side of things is goosed though. Oh well at least we can get heat now.
