Function:
Auto Control Function:
Starts when there is a lack of water or the pressure is lower than the set value in the upper pool. It will automatically pump water.
When the water is full or the pressure is up to the set value in the upper pool it will automatically stop pumping.
Multi-function: you can set the controller to get different functions like water supply, waste drainage, pipe pressure increase, pipe pressure stabilization etc.
Intelligent control function:
'Lack of water' protection in lower pool: When there is a lack of water in the lower pool or pipe, water is not supplied while it is pumping, the controller will automatically switch off in 10 seconds. When the water level recovers in the lower pool or pipe, water is re-supplied. The controller will automatically reset for pumping. If the lower pool is 'no-load' protected it will automatically check every 30 minutes and will commence pumping when there is water.
Overload Protection:
This controller has the feature of 'anti time limit' overload protection. It means that the more over-load current is over than the set value, the faster the over-load protection is.
Lack of Phase Protection:
The controller will switch off in 4 seconds if there is a lack of any of the 3 phases.
Combining the pressure and water level control together: The user only needs to set the switch to the pressure or water level to get the pressure or water level function.
Failure Hint:
If the over-load light is on, the current screen shows overload current.
If the lack of phase light is on, the current screen shows lack of phase.
- 011 - phase A loss
- 101 - phase B loss
- 110 - phase C loss
