manual water return function.
B, there is a pipe temperature sensor
When the manual return water function is activated, if the return water pipe temperature is <35
℃
(default 35
℃
), and the current water tank temperature ≥ return water set tempe return water
temperature difference, return water pump will starts. If the return water pipe temperature ≥ back
water set tempe return water temperature difference for 5 seconds or temperature control
return water time ≥ 2 minutes, the buzzer sounds three times, prompting the user to use hot water;
after 30 seconds, the "
" icon flashes 3 times, buzzing the device will beep for 3 seconds, the
water pump will be turned off, and the “

to start or turn off the timed water return function; the “

The timing return control is as follows:
A, no return water temperature sensor
When the timing water returned function is activated and the timed start time is reached, the water
pump is started. After 30 seconds, the water pump is turned off, and the buzzer sounds three times,
prompting the user to use the hot water; After 15 minutes, the water pump is started again and the
cycle is repeated. .
If press and hold the "cold hot" button for 1 second or the timed return water close time is reached in
this process, the timed water return function will be turned off (the return water function is still valid
for next time, unless the timed return function is turned off).
B, there is a return water temperature sensor
When the timing return water starts, and the start time reaches, if the return water pipe temperature
< return water set temperature, and the current water tank temperature ≥ return water set
tempe return water temperature difference, the return water pump will start. If backwater
pipe temperature ≥ return water set temperature + return water temperature difference for 5
seconds or temperature control return water time ≥ 2 minutes, the water pump will turn off. The
buzzer sounds three times, prompting the user to use hot water; When the pipe temperature <
return water set temperature, the water return pump is started again and the cycle is repeated.
If press and hold the "cold hot" button for 1 second or the timed return water close time is reached in
this process, the timed return function will be turned off (the return water function is still valid for next
time, unless the timed return function is turned off).
Note: When the return water temperature is faulty, it will automatically switch to the “no return water
temperature sensor” mode.
3.5 Anti-fouling function
Sometimes the return pump/circulation pump stops for a long time, the pump will be rusted or
scaled, and the pump needs to be started periodically.
