A computer-implemented method is provided of controlling a heating, ventilation, and air-conditioning (HVAC) system having a heat pump and an auxiliary heater to heat an inside zone, the method comprising: setting values for an economic balance point and a temperature set point; setting a capacity balance point to be equal to the economic balance point; measuring an initial inside temperature in the inside zone and an outside temperature outside of a structure containing the inside zone; determining that the initial inside temperature is lower than the temperature set point; determining that the outside temperature is greater than the capacity balance point; activating the heat pump to heat the inside zone; waiting a heating interval while the heat pump is active; determining that the heat pump is not effective in heating the inside zone; and setting the capacity balance point to be equal to the outside temperature.

Method for controlling an air conditioning system using an economic balance point and a capacity balance point

A system and method for provisioning multiple devices including a commissioning device, one or more endpoints, and a server. The system and method includes the following. The commissioning device accepts user-input network credentials of a wireless network from a user. The commissioning device searches for one or more endpoints unconnected to the wireless network. The commissioning device then verifies the ownership of the one or more endpoints. In response to a positive verification, the commissioning device securely the network credentials to the one or more endpoints. After receiving the network credentials, the one or more endpoints verify the integrity and authenticity of the communication from the commissioning device. After the one or more endpoints verifies the communication, the one or more endpoints access the wireless network based on the securely transferred wireless credentials.
