Horstman Diadem - Changing Timer ?

[steve6469]

i've just moved into a property that has a Horstman Diadem C/H + H/W control.

It's got the basic on/off, twice, all day, 24hr settings with a timer clock so you can set 2 on/off programmes.

I'd like to know if it's possible to change this for a timer that allows you to set more on/off times - a bit like my old central heating control where you had little 'pegs' around the clock which you pushed in/out to set the on/off times ?

is there anything suitable that i can use to swap this over ?

thanks for any advice.

i think it will depend upon your system, gravity, or fully pumped?
if youve got fully pumped their are timers that will do 3 timed settings per day.
