    How to wire a 3 port valve on the UH8-RF controller

    Adam Wroath · 0 replies · Posted

    I'm fitting a wireless control system using UH8-RF to integrate a new underfloor system (3 zones) with old radiator and HW system. My problem is that there is a 3 port valve controlling the radiator/HW flow and I'm not sure how to wire this into the UH8.
    A second question is about the 'boiler enable' shown on the UH8 wiring diagram. The boiler (Grant Vortex 15-26) only requires a switched live supply - i.e. the orange wires from the wiring diagram. I presume I can just ignore the grey wire connection i.e. not take it through to the boiler.
    Any help would

    My electrician has just fitted a Heatmiser Touch RF wireless thermostat and receiver, but they are not pairing up?

    Do we need to change a setting or the frequency?

    Is this a weak rf signal problem or could it be something else

    We have 1 neo thermostat and and rf switch fitted to a boiler in an external garage to control the central heating, it's been in for about 8 months and when set up we realised there were problems switching the boiler on and off from an where but the back window. As the weather has got hotter we have had to move the thermostat away from the window area and we purchased a neo plug in the hope that it would boost the signal, it seems the problem still exists and the boiler seems to turn it self on in
