Cpu controller is electrically connected with built-in water pump;
Cpu controller is electrically connected with outer water pump;
Cpu controller is electrically connected with flow sensor.
Preferably, outer water pump is variable frequency pump.
A kind of control method of the external water pump system of gas-heating water heater, comprising the following steps:
S1:CPU controller dynamically obtains the water route flow value L of system by flow sensor;
S2: when water route flow value L is less than default minimum starting flow value Lq, cpu controller issues instruction, controls outer water pump Starting;
When water route flow value L, which is greater than, presets external water pump operation flow value Ly, cpu controller controls outer water pump and stops fortune Row.
Preferably, when water route flow value L is less than default minimum starting flow value Lq, cpu controller issues frequency conversion instruction, It controls outer water pump and is gradually increased output flow, until flow value L in water route, which is equal to, presets external water pump operation flow value Ly.
The beneficial effects of the present invention are:
It can be chosen whether to open outer water pump according to the actual demand of user, increase the dynamic role of equipment, effectively improve heating effect Fruit reduces expense and pays, high degree of automation, and overall utility is strong.
