摘要： PROBLEM TO BE SOLVED: To provide a hot water supply system which can be configured at low cost and in which second and subsequent hot water supply apparatus can be extended easily. SOLUTION: A main hot water supply apparatus 1a subjected to hot water supply control preferentially is not provided with a water solenoid valve 6 but only a sub-hot water supply apparatus 1b supplementing the capacity of the main hot water supply apparatus 1a is provided with a water solenoid valve 6 controlled by a system controller 2. The water solenoid valve 6 is closed when hot water supply is started and opened with a command from the system controller 2 when the capacity of the main hot water supply apparatus 1a is deficient. Since the main hot water supply apparatus 1a is excluded from control by the system controller 2, a hot water supply system can be configured by simply providing a sub-hot water supply apparatus 1b and a system controller 2 additionally.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption during a relay operation in a driving circuit of a mechanical relay. SOLUTION: In this driving circuit, a zener diode 3 is inserted between a relay 4 and its driving power source Vcc, and a transistor 2 is connected so that driving voltage is can be impressed bypassing this zener diode 3. In starting time of an operation of the relay 4, the transistor 2 is turned on to impress a rated voltage to the relay 4 from the driving power source Vcc, and after the operation of the relay 4, the transistor 2 is turned off to impress a voltage lower than the rated voltage to the relay 4 via the zener diode 3.

摘要： PROBLEM TO BE SOLVED: To implement combustion operation even if a damper malfunctions in a combustion apparatus. SOLUTION: In a combustion apparatus for combustion operation according to a closing position of a valve disk (a damper 60) disposed on a draft route of air toward a combustion part (a burner 30), combustion operation in a small range side of combustion capacity is enabled by recognizing that the valve disk 60 is not driven to a specified position by malfunction of the valve disk 60 on the basis of output of detecting means (a limit switch 62) when the valve disk 60 is driven so as to change draft rate.

摘要： PROBLEM TO BE SOLVED: To ensure the transfer of setting data accompanied by the replacement of a control base board by a method wherein the base board discriminating data of an old control base board are compared with those of a control board retained by themselves and the setting data, transferred from the old control base board, are decided whether the setting data are to be address to and stored in a memory or not in accordance with the result of the comparison. SOLUTION: The version information of a microcomputer is written previously into a non-volatile memory equipped in both of a new control base board 1 and an old control board 2 as base board control data. Upon transferring data between both of the new base board 1 and the old base board 2, setting data and base board discriminating data, which are stored in the non-volatile memory of the old control base board 2, are transferred at first to the new control base board 1. Subsequently, the base board discriminating data of the old control board 2 are compared with own base board discriminating data in the old control base board 2 and only when the version of the microcomputer coincides, the setting data are addressed to the non- volatile memory of the new control base board 1. According to this method, malfunction, caused under a condition that the control data are not coped with the new control base board 1, can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent useless check processing from being performed when a check signal is erroneously outputted or at the time of maintenance and check in the case of controlling a system through communication between equipment. SOLUTION: A solar hot-water supply connection controller 48 holds the value of '0' as an initial flag value. After the equipment is installed, a solar hot-water supply connection unit C requests the response of whether a main hot-water supplier A can deal with that solar hot-water supply connection controller 48 or not and when a response signal from a main controller 4 is received, it is discriminated whether that equipment is a suitable type or not. When the main hot-water supplier A and the solar hot-water supply connection unit C are suited as a result of discrimination, the solar hot-water supply connection controller 48 turns the flag value to '1', holds it and normally operates a hot-water supply system. When the flag value is turned to '1', the solar hot-water supply connection controller 48 does not perform any check even when a check signal is received from a remote controller 51.

摘要： PURPOSE:To shorten a time, required to trial running after second time, by a method wherein only a heat terminal, whose result of past trial running is good or bad, is selected based on data, storing the results of trial runnings of heat terminals, while the heat terminal, whose result of past trial running was good, is excluded upon retrial running. CONSTITUTION:The results of good or bad of heating trial running and cooling trial running of heat terminals 2-6, which are obtained as the results of trial running of this time, are stored in a RAM. When there is any heat terminal, whose result is bad in accordance with the result of automatic trial running, the heat terminal is repaired. Then, the trial running of second time is started by starting a trial running switch 41. The heat terminals are selected sequentially to decide whether the result of trial running of heating of previous time of a selected heat terminal was good or not. The heat terminal, whose result of trial heating of previous time was good, is excluded from the heating trial running of this time. According to this method, automatic trial running after second time can be effected in a short period of time.

摘要： PURPOSE:To facilitate the understanding of a display pertaining to the conditions of devices composing a multiple device system. CONSTITUTION:A multiple device systems is provided with a plurality of devices 1, 2 and 3 connected to each other, remote controllers RC1, RC2 and RC3 (hereinafter called remocons) connected corresponding to the devices, a system controller 4 connected between the devices and the remocons corresponding thereto and a system remote controller 5 connected thereto. While direct transmission or reception between the devices and the remocons corresponding to the devices are made impossible, the transmission or reception of the devices and the remocons are made possible only with the system remote controller 5 separately to separate the devices, the remocons and the system remote controller 5 into groups A-D. Information transmitted from the devices in the groups is displayed on the remote controller of the same group while the newest information alone is displayed on the system remote controller 5 out of that from the devices of all the groups.

摘要： PURPOSE:To make it possible to positively confirm whether the function of a clock is normal or not in an apparatus having the clock function. CONSTITUTION:A first timer means 41 for performing counting as a clock and a second timer means 44 for performing counting of the time based on the synchronizing signal of an apparatus are timed with a timing starting means 55. The counting is performed for a specified period at the same time. In an agreement discriminating means 58, the counted content of the first timer means and the counted content of the second timer means are compared. Whether the clock function is normal or not is discriminated based on whether the agreement is discriminated or not.
