Trying to bind 2 new additional thermostats (THR092HRT). No luck. Tried 10 times with both devices, timeout after 10 minutes each.

I successfully binded half a dozen of the exact same thermostats 3 years ago. They work like a charm until now. However, the new ordered additional 2 units (bought today) refuse to.

Any ideas? Has the product changed in the last years and became incompatible to the older controllers? I have the THR993-RT kit from 2014 with the RFG100. The product codes from 2014 and the new devices are exactly the same.

Thanks for any support!

Hi Dirk,

They should work fine...

Are you following the binding sequence properly?

OK, I'm one step further:

I can get the 2 new thermostats to bind to a new zone each.

However, when the 2nd thermostat bounds to zone2, it drops the 1st thermostat out of zone1 and visa versa.

The problem is reproducible. I can only get one thermostat bound to a zone without "kicking" the other one out.

I had 6 zones working before. Since I can only add 1 out of 2 new ones I can get only a total of 7 zones working simultaneously. Is there a limit on maximal zones of 7?

Is there a way to bound 2 thermostats (which are in the same room) to the same zone?

Thanks!
Dirk
