hi thanks for your reply

not sure tho as system does not allow for central heating on its own , as it is

hw/only or hw/ch together presume that is because of the valve type ??

thanks

have you got a pic of the current timer or describe it better? can't picture it right now...

Which valve is that?
Separate times for ch and dhw gives a much better performance.

thanks for your help but the danfoss mini programmer will give me the hw/only and the hw/ch only settings i require for the system

thanks
