💡 Product Description
The 20Y automatic pump control panel is specially designed for 1-phase single home water pumps (0.37-3KW).
The most significant advantage of the 20Y smart control unit is that it does not require any level electrodes or float switches for dry run protection.
It protects the pump sensitively against dry running and is suitable for submersible and surface pumps in various operating conditions.

❓ Frequently Asked Questions
How do I convert HP into KW for the controller?
The conversion formula is 1HP = 0.74KW. For example, a 3HP pump equals approximately 2.22KW.
Does this controller require a float switch for dry run protection?
No, the 20Y smart control unit is designed to protect the pump against dry running without the need for level electrodes or floaters.
Can it restart automatically after a power failure?
Yes, the controller includes an automatic restart function after power failure recovery and when voltage returns to normal ratings.
What is the typical delivery time for orders?
Sample orders typically take 3-5 days, while standard bulk orders take between 15-20 days.
How can I restore the factory settings?
Simply press both the "Overload" and "No-Load" buttons simultaneously for 3 seconds to restore factory defaults.
What kind of faults can the system track?
The unit features fault tracking and can display the reasons for the last 10 faults, along with audio and light alarms.
