- Page 5 Installation Guide 1. Host Installation: Mount the controller securely on the wall. Open the wiring box and connect the power lines, pump lines, pressure control lines, or probes following the wiring diagram. 2. Signal Line Connection: Ensure that no two probe lines are short-circuited. Avoid contact with the pool wall, stay away from areas with strong interference or electrical appliances, and keep the signal lines separate from power supply lines.

- Page 7 A. Time Setting ‘ON’: After setting the ON time, the controller will automatically switch on the pump according to the set time. The time setting is in hours and operates in a cyclic starting mode. Press the key for 3 seconds and release it upon a beep sound. Upon entering the time setting TIME SETTING mode, “P03”...
- Page 8 3. AUTO/Manual Mode (to switch by pressing the key) AUTO MANUAL A. Under AUTO: In this mode, all functions of the pump controller, such as water supply, drainage, constant water supply, and time setting ON, operate fully automatically. B. Under Manual: In this mode, the pump controller is not controlled by water level or pressure; it is only controlled by pressing the key.
- Page 9 5. No-Load Protection NO LOAD When the working current of the water pump falls below the set no-load current, the pump automatically stops. No-load protection follows an inverse time limit principle: the lower the current compared to the set value, the faster the no-load protection will activate. No—load protection current setting: This function helps control and protect the water pump in cases of water shortage, dry runs, or impeller damage.
