    摘要: A combination thermostat and blower speed control for use with an air conditioner for both heating and cooling air which is circulated through an enclosure by a multi-speed blower.The control has a system switch for selecting either a heating or cooling mode of operation and a blower speed switch for selecting either automatic blower operation or continuous low speed or high speed operation. The combination thermostat and blower speed control has a built-in override such that when the thermostat senses a cooling need and the control is in the cooling mode of operation the blower will operate at high speed notwithstanding the selection of the blower speed at the blower speed switch.

    摘要: An adaptive microprocessor control system and method provide a low heat mode and a high heat mode of a heating cycle in a furnace dependent upon the performance of the previous heating cycle. The duration of the low heat mode and subsequent high heat mode period is a function of the previous low heat mode duration, previous high heat mode duration, and the time period between the end of the previous heating cycle and the beginning of the next heating cycle. The control and method utilize a single-stage thermostat for providing the dual rates of heating.
