Control DHW on-off times but not temp

[RichardRussell]

I would like to use Evohome to control the DHW on/off times but to retain the existing wired thermostat for temperature control (quite enough battery operated wireless devices as it is!). In other words I would use a BDR91 relay (which I already have, left over from a previous installation) but not a CS92 cylinder thermostat. Can I do that?

No, not possible... evohome requires the CS92A to enable the hot water settings on the evohome Controller.
