Had to replace destroyed rdh10 digital room thermostat. Cannot get it to pair to wired controller.
Checked all on line sources, but my RDH10 only has reset button, no learn or test button. How do I pair it?

If it wasn't clear, can't pair the new, replacement RDH ( yeah, I bought it off eBay cause I couldn't afford a brand new one) And the hot water works fine, but have to hit override to get any house heat, then remember to turn it off 30 mins later
