2. Timing change pump function, balance all kinds of pumps' working time . improve the average life of the pumps.
3. Up to 8 periods pressure control, and each period can be set any pressure setting control .and realize the timer ON/OFF function .
4.Sleep function and auxiliary small pump function, save energy and reduce consumption , extend machine’s life.
5. Positive and negative feedback function , can be used for water supply, but also can be used to pump water and maintain the water level.
6.Over-pressure, low water level, sensor disconnection, inverter failure and alarm control functions ect.
7.Feedback can connect with passive remote pressure gauge, active voltage and current transmitter.
8. Feedback device power 0-24V can be modified, stronger commonality.
9. Feedback signals can be selected .it is more convenient to connect with outer .
10. Standard 0-10V voltage output, can also be arbitrarily modified to other voltage values, the application will be more flexible.
11.when the inverter get failure,The controller can choose the automatic transfer to the working frequency running (pressure range control)
12 .Relay fault output function can be selected.
13. Strong adaptable, applicable to various brands frequency inverter at home and abroad.
14.All digital signal use photoelectric isolation, strong interference ability .
15.With complete key function.
For the setting method of the controller, Please see page 6 and 7 of the manual. The working mode is shown in the following parameter settings:
For example：Meter range is 1.6Mpa, users request is set to 1Mpa constant pressure, the controller will start if pressure < 0.6Mpa.
Small Pump setting as below：
With auxiliary pump：
Small pump starting pressure width：F034=0.08 equal (F000-F034=0.92), sleep status，small pump will start if less than the pressure.
Small pump stop pressure width：F035=0.05 equal（F000+F035=1.05），at sleep status，small pump will stop if bigger than the pressure.
Without auxiliary pump：
F033=0; (also can remain and do not change )
