programmer ??? for what . I presume for your heating.
If so it is possible that have not got one. It has always been good practice to install a programmer and a room thermostat when installing a heating system but it wasnt compulsary untill it became part of building regs,part L, April 2005. So if you cant find it on a wall in one of your rooms or in the airing cupboard if you have an airing cupboard that is then you are unlucky i am afraid. You can save alot of money on wasted energy if you get a progamable room stat installed.If you get a RF one (radio frequency) you dont have to spoil your decoration running wires all over your house.
