I set mine up today following Richards excellent videos (loved the 'meet the family' section
) and have had no problems.
I cleared all my HR92s first and then followed the instructions to the letter - including the 5 minutes
The only room I stumbled with was the bedroom which had a DT92 as the temp sensor with an HR92. Managed it ok by doing the DT92 first then binding the HR92 but was a bit unsure about which stage to wait 5 minutes and was a bit thrown by the message (something about 2 way??) so I confirmed it virtually straight away. Think it is ok though but can always unbind delete and redo if necessary.
One thing I can confirm is that the battery low symbol on the front screen works (yay!) I had one HR92 that I hadn't changed the batteries and as soon as I had set it up, I had a message saying that the batteries were low and when I cleared the message, the symbol still showed.
Is the screen made of a different material as it appears to show up fingermarks more than the old one?
One last question - I will package everything up tonight to post tomorrow - what have people ended up doing about the batteries?
