Drayton SM2 how to use.

[mastacrx]

Hi,

I've recently moved into the new flat and can't figure out how to use the central heating. It's a Vaillant Iboiker with Drayton SM2 'programmer. I' ve read the instructions but for some reason the central heating does not work, we still get the hot water all the time though. If i want the heating to be set at 4:30am and 5:00pm once a day how should I set it? I use the tappets according to the manual bimut nothing happens. Another question is how to just turn it on when you wabt it to go in straight away without the timer? I believe it's the advance button. The led indicates the heating is on but heaters are stone cold.


Cheers

Matt

Two times a day use the twice setting with your times set via the pegs

one time a day eg just in the morning use the once setting

24 hours is constant

Ok, thanks. The trouble is when I set it to 24h it indicates by led it's on but it isn't.

Light isn’t on at the timer when it’s on 24 so bad timer I would say
