Abstract: A thermostat includes a microprocessor operatively coupled to and adapted to control a HVAC system. The thermostat also includes a wireless transceiver operatively coupled to the microprocessor and adapted to communicate with wireless routers. The thermostat is adapted to be placed into a listen mode, connect with a remote input device in a direct wireless connection while in the listen mode, receive a Wi-Fi password from the remote input device for accessing a first Wi-Fi wireless network over the direct wireless connection, be disconnected from the remote input device after the Wi-Fi password is received, detect a set of available networks accessible over the wireless transceiver, attempt to login to the set of available networks with the Wi-Fi password, successfully connect to the first Wi-Fi wireless network using the Wi-Fi password, and transmit device information of the thermostat over the first Wi-Fi wireless network to a cloud server.

Abstract: The invention provides a method of inputting a code to a thermostat comprising the following steps, providing a thermostat having a display panel and a receiver for receiving signals from a local router, the local router configured to receive signals via the internet from a remote input device (RID), transmitting a register command to the local router, transmitting new user information to the local router and the thermostat receiving a serial number from the local router and the thermostat synchronizing with the RID without requiring any direct inputs to the display panel of the thermostat. The RID may verify the service set identifier (SSID).
