<P>PROBLEM TO BE SOLVED: To efficiently stabilize capacity by preventing capacity deterioration of a heat pump unit. <P>SOLUTION: Control is carried out by controllers S1 and S2 such that hot water storage operation is stopped on the basis of an output of a hot water temperature detection sensor provided in a hot water storage tank 27, but when a detection output of 55°C or more is inputted into the controller S2 from a predetermined sensor, or operation stop signals are inputted from floor heating remote controllers 3 and 4, and a bathroom heating remote controller 23, the detection output or all of the operation stop signals are transmitted to the controller S1. In the controller S1, when the detection output or all of the operation stop signals is transmitted, discrimination of whether it is a hot water storage stop command or a heating stop command is carried out. If it is distinguished that it is a heating stop command, the controller S1 judges whether or not a first open and close valve 13 for heating is presently opened, and if it is opened, the controller S1 carries out control such that the first open and close valve 13 is closed after passage of a predetermined time such as ten seconds. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
