摘要： PURPOSE:To enable the feed of hot water at the same feed hot water temperature as a set value even when a change in capacity of a hot water feed device with a time is produced by a method wherein, during the use of a hot water feeder, by multiplying a set hot water feed output to be set by a correction factor, an expected hot water feed output is provided, and from the expected hot water feed output, a hot water feed flow rate value to be saved is computed. CONSTITUTION:A temperature Tin of feed-in water and a flow rate Qin of feed-in water are detected a feed-in water temperature sensor 5 and a feed-in water flow rate sensor 4, respectively, and a flow rate Qout to be fed is computed by a control part 10. From a determined set hot water feed output Gset, by using a correction factor (f), an expected hot water feed output Gex is computed. That is, when hot water feed is brought into a steady hot water feed state, an actual feed hot water temperature Tout is detected. Detection is effected by a feed hot water temperature sensor 7, a topmost temperature T1 and a lowermost temperature T2 of a feed hot water temperature are provided, and the feed hot water temperature Tout is determined by a formula 1. When the determined feed hot water temperature Tout does not coincide with the set feed hot water temperature Tset, the correction factor (f) is computed by a formula 2. In this case, in the formula 2, Gre is an actual hot water feed output = (Tout-Tin)Qout and Gset is a set hot water feed output = (Tset-Rin)Qin.

摘要： PURPOSE:To eliminate deviation from the set value in the feed temperature of hot water due to ignition lag of a burner by performing feedback of a time distribution of combustion-on and off for ignition time lag in the combustion-on time. CONSTITUTION:When a hot water faucet of a feed hot water pipe 3 is released, a combustion-on instruction is transmitted to a burner 4 from a controller 10 while an on-time timer at which a combustion-on time is set is started. An ignition detecting sensor 5 detects whether the burner 4 is ignited, and an igni tion lag time till ignition is counted in the controller 10. The ignition lag time shortens a combustion-on time determined so much and the combustion-off time is extended. Therefore, under-and over combustion is eliminated behind a cycle by performing feedback of the distribution of the combustion-on time and the combustion-off time of next cycle for the ignition lag time. When a cycle is for a period of a few seconds, the prescribed feed hot water temperature can be obtained after the delay of a few seconds.

摘要： PURPOSE:To prevent instantaneous boiling and make temperature variation small by storing beforehand a suitable ON time of combustion in a computer by the inflow quantity per unit time and a required heat quantity and selecting an appropriate combustion ON-time from the required heat quantity and actual inflow rate and also calculating a combustion OFF-time. CONSTITUTION:The quantity of fed water, its temperature, and a set temperature are read in a microcomputer 16 to calculate a required heat quantify G1 per unit time, and from this calculated heat quantity and the inflow quantity Q1 a combustion ON-time is selected which is beforehand stored. In this case the whole area is divided into A area, B area, and C area and for each area a specified combustion ON-time is given. Because the required heat quantity G1 is small in the A area, a short combustion ON-time S is given, and because the required heat quantity G1 is large in B area, a middle combustion ON-time M is given, and because, in the C area, lifetime has priority, the large combustion ON-time L is given. A combustion OFF-time is calculated from those combustion ON-times and the required heat quantity G1 per unit time which is calculated, and the heat quantity of combustion per unit time G0 which the burner 3 of a hot water supply device possesses.

摘要： PURPOSE:To prevent damage of parts when the output side of a remote- controlled unit is erroneously connected to a ground by a method wherein a current limiting resistor is connected between an output terminal of an operational amplifier which is remote controlled and a feed-back resistor in a remote controlling device for a temperature in a hot water feeder. CONSTITUTION:An output of an operational amplifier OP1 at a remote controlled part A is divided by a current limiting resistor R6, resistors R3, R4 at an input part of a main control part B and at the same time this partial voltage is fed back to an input side of an operational amplifier OP1 through a feeding-back resistor R1; thereby it is converted into a temperature adjusting set voltage corresponding to a set signal or a sensor signal and then the signal is transmitted to a control part B. In the control part B, the transmitted signal is inputted to an analogue-to-digital converting terminal A/D of a microcomputer CPU through an operational amplifier OP2. In case of connecting the remote- controlled part A with the control part B through their transmittance line, an output part of the remote-controlled part A is connected to a ground and damage of component elements is prevented by the resistor 6.

摘要： PURPOSE:To reduce the number of wicks as a whole and reduce the erroneous connection of power supply lines and signal lines by connecting power supply lines within a remote control part through a switching element, and also connecting main operation switch and a time division signal line to each other in parallel. CONSTITUTION:In a case where power is fed to a feeder connected to a collector terminal of a switching element 31, when automa operation switch 39 is turned on, a low level signal is supplied to the input port of a microcomputer 41 through an automatic drive time division signal line P, and an automatic drive is started. An automatic drive switching element 38 repeats on/off operations in synchronism with a pulse signal. However, since the high level time of the pulse signal is shorter than the low level time thereof, an automatic drive confirmation lamp 39a is substantially put into a lit state. When the automatic drive switch 39 is again turned on during the outputting of the pulse signal, the pulse signal outputting is stopped, and the automatic drive is stopped. By this constitution, the feeder between a control part 40 and a remote control part 30 becomes only a line J, and signal lines become 7 in total.
