Hi, Peter,I think I got the following info from an e-mail which was sent to Access-uk some time ago.
It may be what you are after. Gordon Atkinson "Danfoss 4033 24-Hour Mechanical Programmer TIMED/OFF/ON (Constant) for heating and same for domestic hot water. Off and On override. this switch is available from danfoss randall ltd of bedford. they do a braille version which is very accessible. it has 2 switches, one switch for hot water, the other for the heating system. they are clearly brailled h/w each switch has 3 positions, off, on and timed. there is a rotary dial with dots around it, a little like a braille watch. there is a reference dot so you can use the rotary dial to enable you to set the 24 hour clock. there are 4 colour coded tappets, 2 red 2 blue, one set for each function, namely heating and water. simply slide the tappets to the desired on/off times. the tappets are also marked with tactile markings, a series of different numbers of dots.I think you may have to specifically request a braille version of the timer. this switch is very well designed for a blind person to use. I would suggest giving this company a ring before purchasing, and asking them if it will work with your particular heating system. They have a wide range on offer, and do not forget to ask them if they can supply a Braille version if this is required. Details as follows. Danfoss Randall Ltd.
