    It definitely sounds like a wiring issue. Could you provide details of your set including pictures before and after.

  • Hi,

    The two pictures show how the original Drayton LP722 7 day programmer was wired and how I have tried to transfer the wiring over unsuccessfully as the boiler won't fire up and the three way valve doesn't operate.

    @DG1000 This is a wiring problem. The wires on your new wireless receiver are not labelled? First, your old controller backplate had two brown wires on terminal L LIVE. On the the wireless receiver, the seond brown appears to be on CH NO. Why? Second, the original installer of the backplate has used Green/Yellow on terminal 4. This is a Live wire for CH ON. Not even a brown sleeve to indicate a 'Live' wire? (Dangerous / shudder). On the wireless receiver, it would appear the Green/Yellow wire for CH ON is now parked on Earth. Why? (Shudder). If in doubt, consult a professional.

  • I suggest you open the app. Go into Settings - Rooms & Devices - Wireless Receiver - Installation Instructions and follow instructions for your boiler and use the labels provided - It's not worth double guessing. As @wateroakley mentioned, if you're not competent enough seek a professional.
