The Efficient Home Forum

having just purchased a single zone thermostat y87rf, I am trying to get the relay box to bind with the thermostat.
if I power the relay box up it will click initially then after 3 or 4 secs it will click again.
pressing the grey button will put the green light on.
I cant seem to get the red light flashing.
the actual thermostat can be seen on the evo home controller display,
it switches on and off my master relay box[No 1 box], which I don't want it to do.
but that I think would be a problem with set up.
Has anyone any ideas why the single zone thermostat relay box wont go into binding mode.

You mention evohome? Are you trying to add this as a zone to evohome? Your post is lacking details but page 20 & 21 of the evohome Installation Guide details how to add a zone incorporating a thermostat and relay box to evohome (http://www.honeywelluk.com/Documents/Al ... lation.pdf).
