Abstract
Air conditioning and heating system drives convection fan motor to control distribution of indoor temperature by controlling device with the first sensor and the second sensor, wherein the first sensor and the second sensor is individually connected to controlling device of air conditioning and heating set, and radio transmission device is attached to air conditioning and heating set and remocon. According to difference of temperature between remocon and air conditioning and heating set, main controlling device controls convection motor, electronic pump, driver controlling portion. It has higher heat efficiency by dividing operation of emitting heat and cooling device into more steps.
