    hello, I recently moved into new flat fitted with danfoss tp9000 programmable thermostat for both central heating and domestic hot water. Issue is my heating and hot water both seem to be working all time even though I have programmed on off events in tp9000. The tp9000 indicator light comes on and off as per my timed events but regardless of that my boiler (unvented indirect water boiler) seems to be working all time being controlled by its own thermostat. My understanding is that the boiler thermostat should operate only during the hot water On event in tp9000. Any clues as to what might be broken? The tp9000 is wall mounted and main power supplied without any remote sensor.

    Thx in advance for help.

    No. Homeowner. Have gone thru all manuals provided and played around a bit with different settings but to no avail. Want to get idea of what, if anything, is broken before calling for professional help.
    Thx

    The chances are that the problem is not with the programmer or the
    boiler.

    What is the make and model of your boiler?

    Do you know what type of heating system do you have?

    Does your system have 2 port/ 3 port valves probably in or around
    the airing cupboard?

    Boiler: Range Tribune HE Indirect Unvented Hot water cylinder (manufactured by kingspan)
    Central District Heating system (hydronic)
    Separate zone valves for central heating (1-zone) and domestic hot water
    2 port valve

    Thx

    The Range Tribune HE Indirect Unvented Hot water cylinder is not a boiler.

    It would be best for you to get a heating technician in to check out your
    system.

    The problem likely to be to do with the zone valves but could be something else.
