Electric heater control:
•
At heating mode, when the water tank temperature ≤ set temperature -20 °C, electric
heater starts, and the symbol lights up.
•
When the water tank temperature ≥ the set temperature, the electric heater is turned
off and the symbol is extinguished.
Circulating pump control (water circulation heat pump):
•
When defrosting, water pump is forced to run.
•
When cooling or heating, it is turned on 10 seconds before the compressor and stops
30 seconds after the compressor.
Antifreeze mode:
•
When the controller is powered on, whether heat pump is off or on, when the ambient
temperature is too low, water pump will enter antifreeze mode to prevent the
circulation line or the water tank from freezing.
•
The specific conditions for enabling and disabling the environment for low
temperature antifreeze are as follows:
•
When the ambient temperature is ≤ 2 ° C, and the duration of the circulating
water pump is off for more than 30 minutes, the circulating water pump is forcibly
started for 60 seconds;
•
When the ambient temperature rises to ≥4 °C, the antifreeze mode is disabled.
•
When the ambient temperature sensor is faulty, it is mandatory to start the
circulating water pump periodically, and run for 60 seconds every 30 minutes.
Circulation pump control (optional: uorine cycle heat pump)
Manual water circulation
•
When the controller is in the normal display state, click the “ ” button to start the
manual water circulation function. At this time, the “Back Pump” icon flashes.
The manual return water control is as follows:
No pipe temperature sensor
•
When the manual return water function is activated, the water pump is started. After
30 seconds, the buzzer sounds three times, prompting the user to use the hot water;
after 30 seconds, the “ ” All In One Heat Pump For Domestic Hot Water - 28 - icon
flashes 3 times and the buzzer sounds for 3 seconds.
•
Turn off the water pump and the “ ” icon goes out (if the timed water is set before,
the “Back Pump” and “Timer” icons are displayed).
•
During this process, press and hold the “cold and hot” button for 1 second to
manually cancel the manual water return function.
Pipe temperature sensor installed
•
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 temperature + 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 “ ” icon will be off (if the timed
water is previously set, the “Back Pump” and “Timer” icons will be displayed).
