Did you try by the IP? 192.168.91.1 I believe.Good question, if only the TEG would let me into the commissioning wizard! The guys who normally commissioned it handled the tech the first time.
When I followed up with the procedure in the installation manual and tried it again myself, I get no response from http://teg-XXX so I am not sure what I am doing wrong. I downloaded Opera so the features of chrome weren't messing me up. I will try my laptop next time.
This seems like a silly problem but it's time for me to do the learning clearly.
