I am looking for a wireless CH room-stat/programmer that will control
my DHW as well.
The only unit I can find so far is the Vaillant VRT360F but as
this uses the proprietary eBUS interface it is useless to me.

I simply need a receiver with two N/O relay contacts to control
the two motorised valves in my conventional S-Plan system.

Any recommendations?

Do you need the HW timer to be RF? The stat on the tank has to be fixed, so
you already have some fixed wiring, so adding a fixed timer should be
possible.

I'm currently using this timer from Rapid to control my hot water, which
works well - has battery backup, and a sensible off function. It's current
switching capability is way over that needed for a motorised valve, and it
has a changeover output should you need it.

And you can then choose an RF thermostat to suit your preferences to control
the space heating ( mines a Honeywell CM927, which a lot of people seem to
like too)
