PURPOSE: A boiler having an auxiliary controller for circulation pump control is provided to reduce maintenance costs by preventing unnecessary energy consumption which is generated due to the continuous driving of a burner and circulating pump. CONSTITUTION: A boiler having an auxiliary controller for circulation pump control comprises a boiler part(10), a circulating pipe(30), a return pipe(40), a circulating pump(50), a redemption temperature detection sensor(60), a standard value control device(70), and an auxiliary controller(80). The boiler part heats the heating water flowing in the inside according to the heating temperature of the fixed heating water. The heating water, which is connected and heated with the boiler part, passes through an outlet pipe. The return pipe returns the heating water, passing through the circulating pipe, to the boiler part. The circulating pump is installed in one side of the return pipe and supplies the circulating power to circulate the heated heating water which is heated by the boiler part. The redemption temperature detection sensor detects the temperature of the heating water which is returned to the boiler part from the circulating pipe. The auxiliary controller controls the temperature standard value of the fixed heating water, according to the operation of the circulating pump. |
