    Expensive but good - best price here

    3 Channel Time switch. Have used them in the past when they were made by Horstman. I know of no other that has 3 channels which are needed for a boiler which has central heating, hot water and a cooker

    Great job

    Bought as replacement for old one. Very easy to fit once you get the old one off. Very happy

    The controller itself is great, however the app badly lets it down as it is not at all intuitive, restricted functionality and often doesn’t connect
