Delay control:

When the pressure reaches the action point, the delay action delay time can be set

Can prevent unstable pressure inside the pipe from causing frequent motor action

Password protection:

Lock parameter settings not modified

Protect the set data from being modified

Reverse control:

After the function is activated, the contact opens when the pressure is below the lower limit, and closes when it is above the upper limit

High level start, low level stop

Pressure detection protection:

When no pressure change is detected within the set time. Automatically disconnect the water pump, display E-1, and restart automatically when pressure changes

To avoid water supply interruption due to water source pumping, pipeline leakage, pressure not reaching the upper limit, and water pump idling

Water shortage protection:

When the water pressure is lower than the set water shortage protection value, it will automatically close and click to display E-F. After protection, it needs to be manually started to work

To avoid running the water pump idle under water shortage

Detection time:

Set the time for pressure detection protection and water shortage protection

Used in conjunction with pressure detection protection and water shortage protection
