The Tuhorse control box has some great, advanced, user friendly features. The controller is contained in a water resistant case and is suitable for outdoor use.
Make sure the control box case is closed at all times. Warranty is void if there is moisture damage as a result of the control box case being left open outdoors.
The wire pass through ports at the bottom of the control box come sealed as a factory default. The ports are water resistant provided that there are wires being passed through to the control box. If you have removed the factory seal but are not using the port for whatever reason, then make sure you use silicone to seal the port at the bottom. When operating, the control box will be quite warm and will attract unwanted critters that come through the open ports and once in, these critters will cause damage to the circuit board of the control box. Please make sure that the ports are closed as such damage will void warranty on the control box.
You only need a Philips screwdriver to make electrical connections to the control box.
Below is an explanation of the various lights on your control box.
SYS – A green light indicates that the control box has power and is running.
Pump – A green light indicates that the pump is running. The green light should turn on approximately 20 seconds after the power is connected
MPPT – A green light indicates that the control box is utilising Maximum Power Point Tracking. The Tuhorse control box monitors the solar panel performance and systematically makes adjustments in order to calculate and maintain maximum performance. The MPPT feature improves overall system efficiency, particularly in low light or overcast conditions.
ERR.1 - If this light is on, then it is an indicator that there is a current error. Try disconnecting and reconnecting your solar panel cables.
Low Power - If this light is on, then it is an indicator that there is low power input to the controller. Check for shading, obstructions to your panels or an error with panel connections. This can also occur if the speed dial is turned down too low for the pumping head required. Try these troubleshooting steps for low power.
Tank. F – If this light is red, then it is an indicator that the water or storage tank is full. This will prevent over pumping and water wastage.
Well. L – If this light is red, then it is an indicator that the water in the well is low or unavailable. The pump will automatically stop pumping and will prevent the well from running dry.
