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.

Claims

1. A control method for an air conditioning and heating system comprising:

(A) a remote control control method comprising the steps of;

deciding a desired temperature state at the remote control by reading temperature information input to a keyboard;

displaying said input state on an LCD display;

converting analog temperature data sensed by a sensor attached to the remote control to digital temperature data; and

transmitting said digital data at predetermined setting time intervals;

(B) an air conditioning and heating set control method comprising;

checking the state of a second keyboard input;

deciding the state of an operating switch;

determining said heater and air conditioner set temperature;

controlling driver control means comprising igniter, electronic pump and burner motor;

checking said digital temperature data transmitted from said remote control;

comparing said digital temperature data transmitted from said remote control with said determined heater and air conditioner set temperature; and

controlling fan motor speed to adjust said heater and air conditioner set temperature according to a difference between said digital temperature data transmitted from said remote control and said determined heater and air conditioner set temperature.

2. The control method for an air conditioning and heating system of claim 1, wherein the last step further includes the step of:

adjusting said heater and air conditioner set temperature by increments divided into 1°

C., 2°

C., 5°

C., wherein the increment is chosen based on said difference.
