• Single-control UP pool (water storage) installation instructions shown in figure 1
• A(red)—Upper water level control point. When water level gets to A point,
• the probe touch water and controller can stop the pump by auto.
• B(blue)—Lower water level control point. When water level gets off B point,
• the probe out of reach water and controller can start the pump by auto.
• C(black)—Should be placed in bottom of pool as the common line.
• D(green) and E(yellow)are connected with C (black).
• Single-control DOWN pool(drain water)installation instructions shown in figure 2.
• E—Upper water level control point. When water level gets to E point,
• the probe touch water and controller can start the pump by auto.
• D—Lower water level control point. As liquid level gets off D point,
• the probe out of reach water and controller can stop the pump by auto.
• C—Should be placed in bottom of pool as the common line.

A&B—disconnected

• Lack of water protection installation instructions shown in figure 3.
• C&D—Lower water level control points. When water level gets off this point,
• C or D probe out of reach water and controller can stop the pump by auto.

E&C—short-connected;

A&B—disconnected

• Joint control UP and DOWN pool installation instructions shown in figure 4.
• A—Upper water level control point in UP pool. When water level gets to A point,the probe touch water and controller can stop the pump by auto.
• B—Lower water level control point in UP pool. When water level gets off A point, the probe out of reach water and controller can start the pump by auto.
• C—Should be placed in bottom of UP and DOWN pools as the common line.
• D—Lower water level control point in DOWN pool. When water level gets off D point, the probe out of reach and controller can stop the pump by auto.
• E—Upper water level control point in DOWN pool. When water level gets to E point, the probe reach water and controller can start the pump by auto. Then pool starts to drain water. If not, E point disconnected

Used to solve problem:

• On power but no work
• Check the red indicator is on or not. If not, make the connection is good enough;
• When water level is above or below probes but the pump does not start or stop by auto, Please check it like the following.
• Whether the probe is placed too high or low so that water level can reach or out of reach it;
• The connection of upper &lower line or probe is dislocation by error or short connected;
• To check the probe whether it is rust or not or the connection is good enough.
• C- Check the common line whether it is placed in the lowermost bottom of pool.
