.Hello,
I have recently installed a used Honeywell t7350 thermostat in one area of our building. I want to make some changes in the program which requires me to get into the software. I have downloaded Tstat into my laptop and purchased a usb to rg46 cable to connect. The problem is that the program in the laptop says there is no connection to the thermostat. Does anyone have any idea why I would not be able to talk to this thermostat. Thankyou.
