I finally pulled the trigger on a pellet stove insert. Bought the Quadrafire Trekker insert (couldn’t get the Mt Vernon anymore). But having a lot of trouble getting the user interface to pair. It’s a new unit I’m installing but when I follow the pairing instructions, the interface never pairs and does not respond to inputs. Just shows room temp and “disconnected”. Dealer gave me another one to try, same issue. Can’t navigate to the settings to force it to pair. I’m stuck. My dealer has no idea. When I power the stove it does it’s calibration procedure and the BT dongle flashes like it’s in pairing mode. Any ideas?
