    Heatslave 2 hive single channel

    Hi all Looking for some advice in connecting a hive single channel to a new heatslave ii. Everywhere I look suggests the common (black) should connect to ‘LS’ which I don’t have. If I connect to LR water, nothing happens. Do I need a jumper between common and live? Thank you

    no central heating but DV actuator is operational

    Hi all, I’ve recently moved house and inherited a Worcester green star heat slave 12/18 with a Honeywell wireless thermostat. A day or two ago we lost central heating. The hot water works fine as the boiler fires up. However there is no heat in the rads throughout the house. I bled the rads...
