Thing is it used to bleep when I opened either of the front or back doors but it is not doing it now but it is still going off when it's set
Does that make sense
Trouble is I don't have the manual as I only moved in the house last year so I am just pressing buttons willy nilly
Same with the central heating - the water wont heat up and the radiators are not working - low pressure probably but I dont know how to re-set it
