1.1 Root layerWhen the inverter is powered on and initialized, the homepage of the inverter will apper on the screen.
Press the DOWN buttom, you can see the inverter control page. Under this page, you can control the working status of the inverter.
Again press the DOWN buttom, you can see the valve control page. Under this page, you can control the working status of the valves.
Again press the DOWN buttom, you can see the setting page. Under this page, you can configure the general setting of the inverter.
Press UP buttom, you can return to the previous page. If you want to enter the funcational page, press ENTER buttom when the targe function is appear on the screen. For example, when the "INVERTER CONTROL" page is appearing on the screen, you can press "ENTER" buttom to control the inverter. When you want to exit from any functional page, press "ESC".

1.2 Inverter control layerWhen you are in the INVERTER CONTROL
page at the root layer, you can press the "ENT" buttom to go into the inverter control layer. If you want to return to the root layer from the inverter control layer, you can press the "ESC" buttom. You can press the "UP" and "DOWN" buttom to switch among the subpages of this layer.

1.2.1 Inverter control home pageThe first page of the inverter control is as the following figure shows.
In the inverter control home page, you can change the working status of the inverter and monitor the real time data of the inverter. When you are in the inverter control home page and press the "ENT" buttom to configurate the working status of the inverter. When you are in configuration mode, the Status
block (red block in the following figure) will start blinking.
- OFF: Stop the inverter
- ON: Run the inverter
- RMC: Switch the inverter to remote control mode
Notes:
- There is a sepcial
ERR
status which indicates there is some error in the inverter system. You can find the specific type of the error in the following "Error view and reset" page. When the inverter is inERR
status, you will not be able to chage the working status at this control home page. - It is only allowed to switch to ON or RMC status from the OFF status. When you want to switch between ON and RMC status, you need to first switch to the OFF status. )
When you are in the configuration mode, you can also press the left or right buttom to move the blinking block to the target pressure setting block (as the red block in the following figure shows). Here you can press the up or down bottom to change the targte pressure of the inverter.
After you finished you configuraiton, you can press the "ENT" buttom to save and execute the configuration. And after you press the "ENT" buttom, Status
block or the target pressure block will stop blinking. At this moment, if the Status
block or the target pressure block shows you the value of your target configuration, it means the configuraiton is successful. If the value of the blocks return to the previous value, means the operation is failed. You need to check the setting and re-configurate the working status of the inverter.
And when you are in the configuration mode, ff you want to discard the new configurations, you can press the "ESC" buttom.
The following display row (red block in the following figure) is a monitor data display block that shows the real time water pressure of the pump.
The following display row (red block in the following figure) is a monitor data display block that shows the real time working frequency, current and power to the pump.

1.2.2 Inverter timer pageThe inverter timer allows to run the inverter for a specific duration. When you are in the inverter timer page, you enter the timer configuration mode by pressing "ENT" buttom. You can use the "UP" and "DOWN" buttom to slect the parameter you want to config and use the "LEFT" and "RIGHT" buttom to set the value of the parameter.
For the value of "Timer" parameter, you can select from "ON" and "OFF" to turn on and trun off the timer. For the value of "Value", you can set the duration you want to run the inverter, in minutes. After finishing the configuration, you can press "ENT" buttom to save the setting and enter the configuration mode.
When the timer is turn on and the value is not zero, when the configuration is done, timer will run the inverter and start counting dowm. And the "Remain" block on the screen will shows the remaining time of the timer. When the timer expires, the timer stops the inverter.
#
1.2.3 Error view and reset pageWhen the inverter has some internal errors, the error type will display in this page. However, the errors need to be solve manually. After the error is solved, we can press "ENT" buttom to enter the configuration mode, in which the "RESET" block will start blinking. Then, press the "ENT" buttom again, the inverter will enter the reset procedure.
The possible errors are:
- Overcurrent:
- Over voltage:
- External fault A:
- Instant cut off:
- Input phase loss:
- Ground fault current
- Inverter Overheat
- Electronic thermal
- Overload trip
- Hardware fault
- External fault B
- Param write error
- Cooling fan fault
- Output phase loss
- Inverter overload
- Low voltage
- Keypad error
- SelfDiagnostic fault
- NTC open
- REEP error
- Sensor disconnected
- MODBUS Error

1.3 Valve control layerIn the crurrent system, there are 8 valves. So in the valve control layer, you can use use the "UP" and "DOWN" buttom to select the valve you want to control. To be noticed, it is only allowed to control with timers. When you are in the control page of a specific valve, you enter the timer configuration mode by pressing "ENT" buttom. You can use the "UP" and "DOWN" buttom to slect the parameter you want to config and use the "LEFT" and "RIGHT" buttom to set the value of the parameter.
For the value of "Timer" parameter, you can select from "ON" and "OFF" to turn on and trun off the timer. For the value of "Value", you can set the duration you want to run the inverter, in minutes. After finishing the configuration, you can press "ENT" buttom to save the setting and enter the configuration mode.
If the timer is turn on and the value is not zero, when the configuration is done, timer will turn on the valve and start counting dowm. And the "Remain" block on the screen will shows the remaining time of the timer. When the timer expires, the timer trun off the valve.
