whichever clock you decide to use it will have to have voltageless switching, then you can leave the exsisting clock in and set it to 24 hour mode then remove the link from the roomstat posistion on the pcb and connect it in place of the link, or you can remove the old clock alltogether and use the 2 switching wires back to the new clock you will not need a programmer just a clock
To do it though you should be part P approved for electrical work so you will need an electrictian
