I have a Drayton Wireless System RF1. The thermostat is apparently working well: it indicates the temperature and has that sign of a flame on it. The receiver however displays NO lights at all -- it seems that it is off, with no power running through it.
Despite that, the water is heating. Can I somehow override the wireless system and control the temperature through the worcester device?
locate and trace cable from receiver to boiler (usually 2 core) with the power off disconnect the cable at the boiler and bridge the two terminals the c/heating will now be permanently on don't forget to tape up the cable you've disconnected
