Sime super 90, can not figure out how to switch off heating but not water

[Elamani]

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.

Hi, thank you for your reply. I've tried this and the radiators are still coming on.

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

click that switch up to the summer position and the heating will go off

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?

 

[Elamani]

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!
