    • PURPOSE:To prevent the occurrence of erroneous interruption processing due to a noise, etc., by comparing a zero cross pulse generated at the time when the signal voltage of AC, etc., is below threshold voltage and a false zerocross pulse generated at definite time intervals a counter times with each other, and correcting the counter to generate the flase zero cross pulse when deviation between both the pulses becomes over some definite value. CONSTITUTION:The set time of the counter 10 does not perfectly coincide with the time interval of the zero cross pulse, but there is a little deviation due to the precision of the counter 10. While the deviation is small, it does not exercise influence upon the timing of the interruption processing, but when it becomes large after being accumulated for a long time, the influence appears. Then, the generating timing to of zero cross pulse 5 outputted from a pulse generation circuit 4 and the generating timing (t) of the false zero cross pulse 14 outputted from a false pulse generation circuit 12 are compared with each other, and the deviation ¦to-t¦ between the generating timings of both the pulses becomes over some definite value ts, the set time of the counter 10 is corrected.

    • PURPOSE:To realize bidirectional communication between a steam sauna main body and a remote controller via a power supply cable by superimposing and inserting a second communication signal to a part outside between both edges to which a power is supplied from the power supply cable. CONSTITUTION:At a hot water supply device 2 side and the remote controller 2a, 2b sides, a signal until edge input Er is detected by the rise of a power Sa after edge Ed input is detected by the fall of the power Sa less than a threshold level L is handled as a first communication signal. At the steam sauna main body 6 and the remote controller 6a side, no response is issued in the detection of the edge Ed at that time, and also, the second communication signals Sd, Se when the edges Er is detected and inputted after the rise of the power Sa are handled as the signals between the steam sauna main body 6 and the remote controller 6a. Thereby, even when a hot water supply device as first equipment with specification different from that of the steam sauna is connected to the sauna with the same power supply cable, the bidirectional communication can be realized between them via the power supply cable 4.

    • PURPOSE:To facilitate various control processings corresponding to operating switches provided on each machine kind by providing a switch array conversion processing part for converting an array of each operating switch of a remote controller to a terminal array of each standardized function of a microcomputer. CONSTITUTION:When a machine kind designating switch part 10 of an input/ output interface 6 is operated in accordance with a machine kind of a remote control 1, a machine kind designating signal is outputted, and a data selecting part 14 reads out a switch array conversion processing procedure which is stored in a processing procedure memory 12, and sends out this data to a switch array conversion processing part 16. The processing part 16 converts an input signal from each operating switch of the remote control 1 to a terminal array of each standardized function of a microcomputer 4, based on this procedure. In such a way, even in case of changing a little the array of the operating switch of the remote control 1 in accordance with the machine kind, it is unnecessary to change a module of the operating switch, and also, various control processings can be executed in accordance with the operating switch without changing a main processing program of the microcomputer 4.
