<p>PURPOSE:To enable bleeding of air to be confirmed, by providing a microcomputer, which decides a bleeded amount of air in a warm water circuit by a delivery water amount sensor, while a lamp turned on and off by the microcomputer. CONSTITUTION:A warm water circuit, in which warm water is fed by a pump 3 to heat radiators 4 via a water amount sensor 5 and returned to a heat exchanger 2, is formed. The water amount sensor 5 measures a circulating water amount in the warm water circuit to be input to a microcomputer 6, and it controls a lamp 7 to be turned on and off by the input circulating water amount. In this way, bleeding completion of air in the warm water circuit can be easily confirmed.</p> |
