Replaced a comfort M30 thermostat with new icomfort M30 thermostat. Also saw that the account was never set up in the first place and the WiFi I was never set up as well. Set up the Wi-Fi and the account and the client download the app and hook it up to his phone. Client is very happy at this time but was unable to connect the two system zone on left side of house due to the router being too far away from the thermostat. I let the client know if he can fix the Internet issue towards the left side of the house we will hook up the thermostat to his phone afterwards
