摘要： PURPOSE:To supply desired hot water surely, by finding the required amount of movement of a control valve per unit output-number, on the basis of the relation between the amount of the movement at the time when the control valve is shifted until a first output-number reaches a second output-number, and the variation of these output- numbers. CONSTITUTION:Each position of a control valve corresponding to a first and a second output-numbers is previously detected and stored. On the other hand, the required amount of movement of the control valve per unit output-number, which amount is found by the amount of the movement at the time when the control valve is shifted until the first output number reaches the second output-number, is previously stored. In the case where a hot water-supplying apparatus is used after that, hereby, when a hot-water supply temperature desired is preset, the output-number required is operated by a control part 30, on the basis thereof. As the result of it, the position of the control valve, at which position the hot-water supply temperature desired can be obtained, is operated with both two positions thereof and the required amount of the movement thereof per unit output-number, which are respectively stored previously. Under such a manner, hot water can be accurately supplied, even if each of these hot water- supplying apparatus is not uniform in the quality of its production or the like.

摘要： PURPOSE:To maintain safety operating status even when any momentary suspension is returned at any time by setting data holding time from the occurrence of a momentary suspension of a microcomputer on a main frame side longer than that of a microcomputer on a remote control side in an oil burner, such as a kerosine hot water supply heater. CONSTITUTION:A safety device for an oil burner is provided with a controller 3 on a main frame side comprising a microcomputer 3A on a main frame side and remote controllers ranging from 4 to 6 which have a microcomputer 2 on a remote controller side. The remote control side microcomputer 2 detects occurrence of momentary suspension from an unfeasible state of external interruption while the main frame side microcomputer 3A detects the occurrence of momentary suspension based on the information whether or not data reception on the main frame side is abnormal. Since the main frame side microcomputer 3A has a longer data holding time from the generation of spontaneous suspension, this construction makes it possible to hold safety operating status or suspension status which prevents the start of recombustion.

摘要： PURPOSE: To prevent execution of an unnecessary freezing preventing operation by a construction wherein an indoor heat exchanger of a hot water type air conditioner equipped with refrigerant and hot water circulation circuits starts a freezing preventing operation when the temperature thereof is a freezing preventing control start temperature set beforehand or below and when a set time or a time longer than it passes after a compressor stops. CONSTITUTION: When an indoor heat exchanger temperature Th detected by a heat exchanger temperature detecting thermistor is a freezing preventing control start temperature T0 (e.g. 10 deg.C) set beforehand or below and when a predetermined set time (t) (e.g. two hours) or a time longer than it passes after a compressor stops, a hot water valve is opened and a heat source machine (including a circulating pump) is started. While the circulating pump is turned ON, in other words, combustion of a hot water producing part of the heat source machine is turned ON and thereby a freezing preventing operation is started. Herein the freezing preventing control start temperature T0 is set at a value (e.g. 10 deg.C) lower than a cooling set temperature Ts . Freezing of a hot water circulation circuit can be prevented reliably without conducting an unnecessary freezing preventing operation.

摘要： PURPOSE:To improve temperature control characteristics in defrosting operation by switching a heating capability control method in response to detected heat carrier temperature or heat carrier temperature set to a heat refrigerant heater. CONSTITUTION:When the operation is judged to be a cooling operation (S42), the cooling operation is performed (S44). When the operation is judged to be a heating operation (S45), a heater carrier request temperature signals is transmitted to a heat carrier temperature control part such that a high temperature heat carrier is supplied (S47). Thereafter, the heat carrier request temperature signal is transmitted to a room temperature control part (S48), and a heating operation by an ordinary control operation is performed (S49). Further, when the operation is judged to be a defrosting operation (S50), the heat carrier temperature request signal is transmitted to the heat carrier temperature control part such that it supplies a low temperature heat carrier (S52). When heat carrier set temperature received by the room temperature control part (S53) is not higher than the request temperature (S54), the ordinary control operation is performed, while when the received heat carrier set temperature is higher than the set temperature, low capability control operation is performed (S56).

摘要： PURPOSE:To provide a positive prevention of freezing in a device by a method wherein when an environmental temperature is lower than a specified value, a freezing prevention automatic switch is turned on, a freezing prevention heater is turned on and then a circulation pump is turned on under a condition in which there is an abnormal circulation in bath and bath tub water or an abnormal sensing of bath temperature. CONSTITUTION:When an environmental temperature is decreased and a freezing prevention automatic operation switch 37 is turned on, a controller 60 turns on a freezing prevention heater 38 with this signal to start heating of a circulation passage. The controller 60 further checks if a bath furnace 10 is in a safe operation under a well-operating state or not and if the safe operation is assured, the circulation pump 32 is turned on. If the safe operation is not carried out and the bath automatic temperature keeping operation switch is not turned on, the circulation pump 32 is turned on. If the bath automatic temperature keeping operation switch is turned on, in principle, the bath automatic temperature keeping operation is preferentially carried out. When an abnormal circulation of the bath tub water is detected and an abnormal detection of the bath temperature is carried out, the circulation pump 32 is turned on.
