5.2 Startup:
When the power is switched on, the screen will be fully light for 5 seconds, the device code will
be displayed, and then it will enter the normal working state. When the screen is locked, only
the button will light up; Press and hold for more than 3 seconds, other buttons will
all light up. The screen will automatically lock up when there is no operation for more than 1
minute and the brightness of the screen is reduced by 1/3 of the normal display. Short press
to wake up the screen and observe the relevant operating parameters.
5.3 Self-priming
When switched on for the first time after installation, the pump will start self-priming
automatically and followed by self-learning.
1) Self-priming:
The system performs the self-priming in Boost mode, it will count down from 1500s and stop
automatically when the system detects the pump is full of water, then the system will recheck
for 60s again to make sure the self-priming is completed
2) Self-learning:
After the self-priming is completed, the system will perform the first time self-learning for 180s,
and redefine the flow range of the pump by detecting the pipeline pressure.
eg: the default flow range of InverHero IH24 is 5-25 m³/h, after self-learning, the range may be
redefined to 7-22 m³/h.
The default flow range for InverHero is as below:
Model Default flow rate range
³
IH24 5~25 m³/h
Remark:
The pump is delivered with self-priming enabled. Each time the pump restarts, it will perform
self-priming automatically. The user can enter the parameter setting to disable the default
self-priming function (see 5.8)
If the default self-priming function is disabled, and the pump has not been used for a long time,
the water level in basket may drop, the user could manually activate the Boost mode of
priming to fill it (see 5.8), the adjustable period is from 600s to 1500s (default value is 600s).
The user could press for more than 3 seconds to exit the Boost mode, The system will
have a 180s self-learning process after end the Boost mode.
