Abstract: A system and method for transporting cool fresh outside air into an occupied quarters which has an interface member, input connectors, output connectors, switches, and a microcontroller controllably coupled to the plurality of switches. When the thermostat controller system is operating during a heating period, the switches are closed by the microcontroller such that the thermostat controller system controls the operation of the remote air-handling unit that heats air provided to an occupied quarters. When the thermostat controller system is operating during a cooling period, the switches are opened by the microcontroller such that the thermostat controller system no longer controls the operation of the remote air-handling unit when a temperature of outside air is at least less than a cooling set point. The microcontroller operates a remote fan to draw the outside air into the occupied quarters when the outdoor air temperature is less than the cooling set point.

Abstract: A system and method for cooling a building using cool fresh outside air is disclosed. When the integrated thermostat is operating during a heating period, the integrated thermostat operates a remote air conditioning unit, such as a furnace, an HVAC unit, an electric baseboard heater, or a heat pump, to heat air provided to the building interior. When the integrated thermostat is operating during a cooling period or a fresh air cooling period, the integrated thermostat compares the indoor air temperature with the temperature of the outdoor fresh air. The integrated thermostat operates a remote fan, such as a whole-house exhaust fan, to draw the cooler fresh air into the building interior in response to the outdoor air temperature being less than the indoor air temperature and/or in response to the indoor temperature being greater than a fresh air cooling set point stored in the memory.

Abstract: A system and method for controlling the operation of a vehicle radiator fan motor is provided. One embodiment receives one of a low-speed radiator fan control signal or a high-speed radiator fan control signal from an engine control module; provides a first soft start of the radiator fan motor in response to receiving the low-speed radiator fan control signal, wherein the first soft start is defined by a first increasing power ramp that starts at a zero-power level and ends at a low-speed power level; and provides a second soft start of the radiator fan motor in response to receiving the high-speed radiator fan control signal, wherein the second soft start is defined by a second increasing power ramp that starts at the zero-power level and ends at a high-speed power level.
