BIASI TIMER AGAIN

[BrynRovers]

I am looking for an external timeswitch for my Biasi 28S boiler, mainly because the Biasi switch seems to create more problems than it's worth.
As far as I can see from the circuit it would need a timeswitch with "floating" contacts.
All the timers I have seen so far have the time contact internally connected to live.
Any ideas ?

drayton 241(i think) and horstmann H17 timeclock suitable ask for a voltage free clock (and check they give you the right type)

as posted below LP241 (24 hour 1 channel) i knew it honest

Drayton LP series are naturally low voltage too.
