Hi,

The CH and HW is driven by a Danfoss 24-hour `clock face' timer that has
two on-off periods a day.

Any one in particular?

It's six terminals seem to be wired

1 switched live output
2 unused
3 switched live input, connected from 6
4 earth, not connected - is this normal?
5 neutral
6 live

I'm looking for a digital replacement so I can time things more
accurately. Do these things typically fit to a standard backplate so
the existing hole in the wall can be re-used?

My main reason for posting is I'd like more on-off periods a day but 3-4
seems to be the maximum. Anyone know of a 24-hour, or maybe 7-day,
timer that has more, e.g. 6?

Thanks.

Sam.
