<P>PROBLEM TO BE SOLVED: To enable the operating time of a heat pump unit of large power consumption to be integrated and to enable a user to easily judge the operating time with inexpensive constitution. <P>SOLUTION: When a signal to the effect that the heat pump unit A is in operation is transmitted to a tank unit B, a first control device 31 can acquire the purport of the heat pump A being in operation. In this case, every time a timer 44 outputs a time-up signal, a night counter 45 when it is in a night power time zone and a day counter 46 when it is in time zones other than the night power time zone recognized by a clock 43 are incremented by "1". The first control device 31 computes the operating time of the heat pump unit A in the night power time zone and in the other time zones by multiplying the counting frequency of the night counter 45 and day counter 46 by 1 minute and makes time displays on display devices of a bath remote control 40 and a kitchen remote control 41. <P>COPYRIGHT: (C)2008,JPO&INPIT |
