This circuit can be used to control the 5℃ to 35℃indoor temperature or other heating equipments. The maximum heating power depends on its thyristor,this one issuitable for 2kW power, and thyristor is BT139. Temperature is controlledby the bridge road which composed by thermistors, resistance R1 and potentiometer Rp, the actual voltage and given voltage respectively adds on the U6 and U9 of integrated flip-flop TDA1023. If the room temperature is far belowthe given temperature,heating machine workswith all the power. If the room temperature is 1K differ from the given temperature,the proportional adjustment will be achieved.
