Abstract: An appliance is placed in a bootload mode and other operations of the appliance are powered down. Data is gathered through an appliance control module which activates the bootloader mode, and then receives the data and overwrites the remainder of the appliance controller memory. In this manner, software for an appliance is updated without having to enter the home.

Abstract: A system and method for controlling operation of a hybrid heating system that includes a heat pump and a gas heater is disclosed. Peak demand or pricing information is received from gas and electric utilities, and outdoor ambient temperature data is also fed to a smart hybrid thermostat. A controller processes this data and calculates overall efficiency of operating the heat pump versus the gas heater by accessing stored performance data relating to the heat pump in memory.
