Abstract:
An air comfort control device comprising, in combination:a furnace fan; a blower motor for rotating the furnace fan at a high speed and a low speed; a temperature controller responsive to temperature changes in air in a partially enclosed environment and adapted to receive fan input signal; a motor controller which in response to a fan output signal from the temperature controller applies a first voltage to actuate the blower motor so that the furnace fan rotates at the high speed and a second voltage different from the first voltage to actuate the blower motor so that the furnace fan rotates at the low speed; and a mode input signal received by the temperature controller, which corresponds to one of an automatic mode of operation wherein the furnace is automatically actuated to change the temperature of the air to the desired temperature, and a manual mode of operation wherein the furnace is manually selected to change the temperature of the air to the desired temperature.
