PROBLEM TO BE SOLVED: To provide a method of collecting information about the use condition which enables a user to monitor the use conditions of a heat source unit constituting a central heating system and a terminal apparatus connected to this. SOLUTION: This is a method of collecting information about the use condition of a central heating system which has a heat source unit and a terminal apparatus being connected to this power source unit through a hot water supply pipe and an in-system communication means. In this method, the quantity of used heat and the integrated quantity of heat of the above heat source unit are counted and preserved, and in correspondence to the terminal apparatus, the open time of a thermal valve or a flow variable valve is integrated and is preserved in the above terminal apparatus, and the above heat source unit collects and stores the information about the integrated open time of the thermal valve or the flow variable valve preserved periodically in the above terminal apparatus, and transmits the information collected from the above heat source unit to a diagnoser connected to the above heat source unit through a communication means thereby enabling the display of those use conditions separately for each heat source unit and terminal apparatus. |
