I have a Saunier Duval F24 combi with an analogue timer. Apparently there is an electronic programmer kit available SD part A20087. Are these simple to exchange, and can anyone recommend a supplier for the kit.
Thanks for your response - that hadn't occurred to me. The main objective is to provide different settings for on/off on different days of the week. Can a programmable thermostat provide that?
So is it a case of unplugging the wiring for the existing timer and replace with the new one - is the wiring going to be the same? Or, is there any way I can make sure the wiring will be the same.
