HVAC control with a remote user interface and a remote temperature sensor

An HVAC controller for an HVAC system that is configured to condition a living space within a building, the HVAC controller comprising:

• one or more transceivers for wirelessly communicating with a network, the one or more transceivers configured to communicate with a remote server via the network and configured to wirelessly communicate with a remote temperature sensor that is situated remote from the HVAC controller and in the living space of the building;
• a controller operably coupled to the one or more transceivers, the controller is configured to:
• receive a sensed temperature signal from the remote temperature sensor;
• receive a temperature setpoint via the network;
• implement a thermostat control algorithm to generate one or more control signals,
• wherein:
• the HVAC controller is located inside a housing of the HVAC system, wherein the housing of the HVAC system includes one or more HVAC components, wherein the one or more HVAC components comprise one or more of a blower, a heat exchanger, a burner, or a gas valve;
• wherein the HVAC system does not include a remote temperature sensor capable of changing the setpoint;
• the one or more control signals are provided by a wired connection to the HVAC system to control one or more HVAC components of the HVAC system;
• and
• the thermostat control algorithm is configured to use the sensed temperature signal received from the remote temperature sensor via the one or more transceivers and the temperature setpoint received via the network.
