Optionally, a stop valve may be disposed at a sanitary water inlet or a sanitary water outlet of the at least one flow path to cut off the flow path when the stop valve is closed and not to limit the sanitary flow when the stop valve is opened, the throttling device may include an orifice, a flow-limiting ring or a memory alloy, and the state of the stop valve may include a normally open state or a normally closed state. Taking the bathroom water pipeline as two parallel flow paths as an example, if the stop valves (generally, solenoid valves) on the flow paths are closed, the bathroom water can only pass through the throttling devices on the flow paths, at this time, the bathroom flow is limited by the throttling devices, the bathroom flow is small, wherein the throttling devices of different specifications correspond to different bathroom flow limiting amounts, and if the stop valves on the flow paths are opened, the bathroom water can simultaneously pass through the two parallel flow paths, at this time, although the throttling devices on the flow paths limit the bathroom flow of the flow paths, the stop valves on the other flow paths do not limit the bathroom flow, the bathroom flow is only related to the water pressure of the user's home, and the bathroom flow is large under normal water pressure.

Specifically, as shown in fig. 2, the method for controlling a wall-mounted gas boiler includes:

and S101, detecting that the user starts to use the bath water, and controlling a stop valve to be opened.

That is to say, after detecting that the gas hanging stove ignites and burns, adjust the aperture of the gas proportional valve of gas hanging stove according to bathroom demand load to the firepower size of adjustment gas hanging stove, thereby, make the leaving water temperature of gas hanging stove reach the setting leaving water temperature, end the operation until the user closes the water machine.

Further, as shown in fig. 5, after the stop valve is controlled to be kept in the open state and ignition combustion of the gas wall-hanging stove is detected, the control method further includes:

and S3021, controlling the stop valve to close when the required load of the bathroom is detected to be greater than the rated load of the gas wall-mounted boiler.

That is to say, keep the on-state at the control stop valve, and detect gas hanging stove after the burning of igniteing, if detect that bathroom demand load is greater than the rated load of gas hanging stove, at this moment, can think if continue to control the stop valve and keep the on-state, then the gas hanging stove can't heat bathroom water to the present temperature of setting for water outlet, consequently, for satisfying user's temperature demand, the control stop valve is closed to reduce the bathroom flow of gas hanging stove, promote the heating capacity of gas hanging stove.

Further, as shown in fig. 6, after the stop valve is controlled to be closed and ignition combustion of the gas wall-hanging stove is detected, the control method further includes:

and S3022, controlling the stop valve to open when the required load of the bathroom is detected to be less than or equal to the rated load of the gas wall-hanging furnace.

That is to say, close at the control stop valve, and detect gas hanging stove ignition burning after, if detect bathroom demand load and be less than or equal to the rated load of gas hanging stove, at this moment, can think if continue to control the stop valve and close, then the gas hanging stove can produce extra energy consumption, is unfavorable for energy-concerving and environment-protective, consequently, under the prerequisite that satisfies user's temperature demand, control stop valve opens to promote the bathroom flow of gas hanging stove, further promote user's use and experience.
