The invention discloses a fire size remote regulating device with sensitivity cold temperature compensation of a gas
water heater. The fire size remote regulating device consists of a first flow measuring unit, a second flow measuring unit, an
adder circuit unit, a cold
water temperature measuring unit, a proportional value calculating unit, a flow threshold value switching unit and a
proportional valve drive unit. The gas
water heater comprises a first hot water outlet and a second hot water outlet, and the hot
water temperature is changed by adopting a method of controlling two-way hot
water flow through a water valve; when the hot
water flow of the first hot water outlet is relatively increased, burning fire of the gas
water heater is increased, and the hot
water temperature is increased; when the hot
water flow of the first hot water outlet is relatively reduced, the burning power of the gas water heater is reduced, and the hot water temperature is reduced; and regulating sensitivity is subjected to compensation control by virtue of the inlet cold water temperature of the water heater. According to the device, a wired or
wireless remote controller is not required, remote regulation on the hot water temperature of the gas water heater can be realized, and the control results are stable and reliable.
