Displays the word "Run" and its push button, a column to display when combustion is in progress, a number indicating the set hot water temperature, and an up/down switch for setting the hot water temperature.

Figure 5 is an example of a water heater that has the function of reheating hot water in the bathtub, and shows an operation button, a column that displays that reheating is in progress, a number indicating the bathtub water temperature, and a close-up of the button. Displays a down switch, a column to display that hot water is being supplied, a number indicating the hot water temperature, and an up/down switch for setting the hot water temperature.

FIGS. 6(A) to 6(F) show an example of application to a fully automatic bath device with a hot water supply function.

When the fully automatic bath device pattern is selected, first, as shown in FIG. 6(A), an operation button, a setting change button, and the set hot water temperature, bath temperature, and bath water level are displayed. (In addition, in Figure 6, the area surrounded by spots indicates that input is accepted.) In this state, if you press the setting change button, the display will be changed as shown in Figure 6 (B), for example. .

That is, a hot water supply temperature change button, a bath temperature change button, a bathtub water level change button, an up/down button, and an "other" and "end" button are displayed, and each temperature and water level at that time are displayed numerically. You can change the set numbers by pressing either button for ``hot water temperature'' or ``bathtub water level.'' Once you have finished setting the temperature and water level, press the "End" button to return to the initial screen shown in Figure 6 (A).

Further, when the operation button is pressed in the state shown in FIG. 6(A), the display is changed as shown in FIG. 6(C), for example. In other words, the fully automatic operation button, the bath operation button, the warm button, the warm button, and the stop button.
A setting change button will be displayed, and if you press the fully automatic button in this state, the display on the LCD panel will change to the display showing the status of fully automatic operation as shown in Figure 6 (D), and 0 operation will begin. When the water has been filled at the set water level and constant temperature a, the operation shifts to heat retention operation, and the state is shown in Figure 6 (E).
).

In addition, at this time, if the water temperature in the bathtub falls below the set value, reheating operation will be automatically performed, and if the water level in the bathtub becomes lower than the set water level, hot water will be automatically supplied to the bathtub up to the set water level, as in the past. be.

When a certain period of time, e.g. 4 hours elapses from the start of fully automatic operation, or the stop button is pressed, the display on the liquid crystal panel changes as shown in Fig. 6(F), and at this time, the bath water level changes to reflect the current state. It shows.

〔Effect of the invention〕

(A) to (F) in FIGS. 4 to 6 show examples of displays according to the present invention, but in the present invention, various display patterns are stored in the control board on the gas equipment main body side. Since an arbitrary display pattern can be read and displayed by operating the hand-held operation unit, a single remote control device can be used for various types of equipment.
As exemplified in A) to (F), in the case of devices of the same model, the display pattern can be changed according to the operating situation, which has the effect of improving usability.
