  • Yes, it will pair and work with your existing receiver.

  • As long as it is a TLX1010 or TLX1012.
  • There are 5 terminals on the receiver that are normally wired as follows:
    N - Neutral
    L - Live
    ON - Output to motorised valve or boiler
    COM - Switched live from programmer
    OFF - Not normally used
  • It does require a permanent live, so you will need to either add one, or install the receiver next to the programmer instead.

  • Nothing will connect to the existing receiver.

    This will replace it, but you will need to replace the receiver with the one included.

  • It is fairly simple.  Live, Neutral and two control wires.  If you can change a plug, then you should be OK.


  • It is 30m in open air.  Walls and ceilings will lower this depending on construction.

  • Yes it will.

  • Yes it is.
  • Yes it is.
  • Yes it is.
  • As the receiver is mains powered, you will need to place the receiver near the boiler or airing cupboard. The 2 wires to the existing wired thermostat are not enough.
  • No they will work fine with several in a home.
  • Yes it will. You will need to replace the receiver with the one included.
  • Hi. The TLX7501 was wired. Could it be a TLX7506? If so, yes, this is the one you need. The receiver is included.
