1. CHARACTERISTICS
This digital controller starts and stops pump through MCU according to water flow and pressure.
Completely replace the traditional pump control systems, which composed of pressure tank, pres-
sure switch, water shortage protection set, check valve etc. Compared with traditional electronic
pressure control, this controller has the following obvious features and advantages.
Three modes:
Pressure mode
Pump motor through MCU Receive pressure data and flow singal to control pump start and stop.
And implement relative protection and failure display function
Time mode
Pump motor through MCU receive flow signal to control pump start and stop.
Start again according to set time, and implement relative protection and failure display function.
Flow mode
Pump motor through MCU receive flow signal to control pump start and stop.
And implement relative protection and failure display function.

4. DEBUGGING AND OPERATION INSTRUCTION
1.setting working mode
Press “ model” button, choose “pressure” “time” or “flow”, then
mode light on.Pressure mode is mainly used for no tower water
supply.The function is same as normal electronic pressure control,
you can set the starting pressure. The pressure gauge on the side
shows the system pressure . Starting pressure can be adjusted
on the head body of controller. Generally, it rotates 180 degrees,
and the starting pressure change 0.1bar. The adjustable range is
1.2-2.5bar, and the default is 1.5bar.This mode is factory setting.
install see Diagram 3
“Time” mode mainly used for mainly used for water replenishment
of water tower ,it avoids the user to start or stop the pump by
themselves frequently. The user can set up how long to start
again after filling up the water according to the amount of water
consumed each day. The set time can choose at 0.5h/6h/24h,
which means half an hour/6 hours/24 hours. When water is in
urgently need, it can reset by pressing the reset button to restart.
If the self-priming pump cannot discharge water in 12s, you can
long press the "Reset" , then pump will keep running.
Install see Diagram 4
3.“Flow” mode mainly used for water tower pressurization.
When the user's water consumption reaches a certain value,
the pump will be started and the pipeline will be pressurized.
The advantage is that when the water consumption of the
pipeline is lower, and it is no need to turn on the water pump,
avoiding suddenly start the pump at night , like the toilet
water supply at night. Install see Diagram 5
4.Under the pressure model, if the current pressure value less than
the starting pressure value, and no water flow signal within 12S, it is
determined to be water shortage and appear relevant indicators.
The electric pump will run by itself for 10 seconds every 15 minutes,
start normally working with water entering, If there is still without flow,
no pressure, and then start shut down protection again. Then run 10s
after another 15 minutes, and keep circulating. Pump will normally
operate when detected water pressure.
5.Frequently start within 3 minutes (no flow signal within 3 minutes,
pressure signal repeated ) more than 18 times, and the failure light
means leakage protection. Leakage protection does not affect the
pump’s normal operation, will not be forced pump shut down.
6.The pump can be restarted by pressing the "Reset"
button at any time.

1. Installation and maintenance the cotroller must be operated by
professionals who proficient in this manual.
2. This product only can be used in the clean water, the user
should check the water of pipe system before installation. If the
water containing the iron ore and iron oxide, the pressure control
will be failure after using at time.
3. This controller should be install on the pump which meet the
requirements. The user should install a check valve in the inlet of
the pump, test the pump first before install the pressure control to
make sure the pump have no problems.
4. The controller can be installed directly in front of the first outlet
and the direction of water flow should be in accordance with the
direction of arrow shown in the controller.
User should use the tube connect the outlet of controller and other
pipeline.
5. Don´t leave the other foreign object inside the controller to avoid
the controller failure.
6. The controller must be perpendicular to the horizon after insta-
llation, and the distance between the highest position of the tap
and the vertical distance of the controller outlet can´t be more than
x meter. (The detail data refer to the diagram 2). Concrete installa-
tion refer to Diagram 1

6.SUGGESTION
Try to suggest the clients to choose the suitable mode, operation instruction please refer the pic.
7. WARN I NG
1.The controller can't be used in the medical treatment or the system whichin the event of
failure will cause serious personal injury or property damage.In the maximum extent permitted
by low .the supplier and the agency will not he responsible for the damage which caused by
something in additionto the controller of any direct or indirect at any time.
2. The controller itself have no repair parts provide to the user , it must be maintenance e by
the relevant professionals and the control box can be,provided by standby application.
3. Cannecting the controller power and. pump must be. use the three core rouna caole. In order to
Keep security,the earth wire must be connected in correct way!
The supplier and the agency should reserve all rights of controller instructions, including but not
limited to the copyright interpretationand the right for further amend. When the instruction is modi-
fied forgive that it without prior notice.
