    Hi,

    I have a Sime Super 90 which was in the property when I moved in and there is no manual anyway, I found one online and it really doesn't help. Basically I want to keep the Hot water so it comes on when I turn the hot tap/shower on but switch the heating off as it's a top floor flat and very very hot! I had it like this when I moved in but there was an issue with a fuse and the settings got messed up and now I can't figure out how to put them back, I've tried but the radiators keep coming on just when I think I've succeeded. Thank you very much for any help!

    Is there a summer/winter rocker switch (sun symbol/frost crystal symbol) on the left of the boiler panel?

    Push it up to the "sun" position.

    What settings got messed up ? your boiler only has a mechanical time clock and a summer/winter switch, what other controls do you have

    Well if I knew that I wouldn't be having so much trouble lol, there are more controls than a clock and Summer Winter though, I will upload a photo. as I said switching to Summer is not making any difference. Thanks

    That is the summer position, the other is a snowflake, they look annoyingly similar. I've had it on both now and they still keep coming on. Driving me nuts! Thanks

    Is there a room thermostat on a wall somewhere?

    Who removed the boiler casing and why?

    No, no thermostat, and it was just like that when I moved in, its an old building converted to flats in the 80's. I love it but it has its problems!
