I have just replaced a HWS and cannot get the 50.0 remote to pair. I use two remotes, a 40.0 and the 50.0. The new HWS came with U232 software and did not recognize the 50.0 remote. So, I paired the 40.0 remote. That worked well and all the timers transferred successfully. I waited for the HWS to update which it did overnight. I had the U237 software the next morning. However, I still cannot get the 50.0 remote to pair. Both remotes were unpaired from the old HWS. Any ideas on how to get the 50.0 remote paired? I tried to pair again last night which was three days after the update to U237.
