Mike,

That fixed it - new RoomStat needed..

Oh, dear: it couldn't be the batteries, could it, I'm not sure how
important they are.

We've got a Honeywell room stat in the house we recently bought - there
was enough charge in the batteries for the display to work and
everything to look normal, but not enough to operate the relay.

It definitely might be worth changing the batteries (if it has any!)

Regards,

Steve
