1、When the product is operating, if the function mode is switched, the product will stop working and enter protection mode. All red indicator lights will flash, indicating a function failure. At this point, the user needs to restart the power for the product to perform the corresponding function. 2、In the three-electrode mode, if the high/low water level probes are connected in the wrong order, the product will issue a corresponding alarm. The user needs to correct the wiring order of the probes for the product to function properly. |
Adjustable sensitivity, adjustable delay
Ten function modes:
Three-electrode water supply automatic control (with delay)
Two-electrode water supply control (on delay)
Two-electrode water supply control (off delay)
Two-electrode water supply control (on delay with full water alarm)
Two-electrode water supply control (off delay with full water alarm)
Three-electrode drainage automatic control (with delay)
Two-electrode drainage control (on delay)
Two-electrode drainage control (off delay)
Two-electrode drainage control (on delay with water shortage alarm)
Two-electrode drainage control (off delay with water shortage alarm)

Three-Electrode Automatic Water Supply Control (with Delay) |  |
When the water level is below E2, the delay starts. After the delay, the relay engages. When the water level rises to E1, the delay starts, and after the delay, the relay disengages. This cycle repeats. |
 |
Two-Electrode Water Supply Control (On Delay) |  |
When the water level is below E2, the delay starts. After the delay, the relay engages. When the water level returns to E2, the relay disengages. This cycle repeats. |
 |
Two-Electrode Water Supply Control (Off Delay) |  |
When the water level is below E2, the relay engages. When the water level returns to E2, the delay starts. After the delay, the relay disengages. This cycle repeats. |
 |
Two-Electrode Water Supply Control (On Delay with Full Water Alarm) |  |
When the water level is below E2, the delay starts. After the delay, the relay engages. When the water level rises above E2, the relay disengages. If the water level continues to rise above E1, a full water alarm is triggered. This cycle repeats. |
 |
Two-Electrode Water Supply Control (Off Delay with Full Water Alarm) |  |
When the water level is below E2, the relay engages. When the water level rises to E2, the delay starts. After the delay, the relay disengages. If the water level continues to rise above E1, a full water alarm is triggered. This cycle repeats. |
 |
Three-Electrode Automatic Drainage Control (with Delay) |  |
When the water level is above E1, the delay starts. After the delay, the relay engages. When the water level drops below E2, the delay starts. After the delay, the relay disengages. This cycle repeats. |
 |
Two-Electrode Drainage Control (On Delay) |  |
When the water level is above E2, the delay starts. After the delay, the relay engages. When the water level drops below E2, the relay disengages. This cycle repeats. |
 |
Two-Electrode Drainage Control (Off Delay) |  |
When the water level is above E2, the relay engages. When the water level drops below E2, the delay starts. After the delay, the relay disengages. This cycle repeats. |
 |
Two-Electrode Drainage Control (On Delay with Low Water Alarm) |  |
When the water level is above E2, the delay starts. After the delay, the relay engages. When the water level drops below E2, the relay disengages. If the water level continues to drop below E1, a low water alarm is triggered. This cycle repeats. |
 |
Two-Electrode Drainage Control (Off Delay with Low Water Alarm) |  |
When the water level is above E2, the relay engages. When the water level drops below E2, the delay starts. After the delay, the relay disengages. If the water level continues to drop below E1, a low water alarm is triggered. This cycle repeats. |
