I am living in the building located in Dubai where I have two York
split ducted ac installed. There are 4 wires coming to thermostat
(Red-Black-White-Yellow). Could you please tell me Nest 3rd generation
thermostat (T3021US) is compatible or not?
Hi Ryan,Thank you for your reply. One technician install Nest on the
same system and working perfect. I am sharing you the pictures of the
device which he use. He bypass the existing PCB board and use the new
device. Could you please tell me what is...
