Installation

Before pairing the app, the device needs to be installed: mounted, wired to the pump, and the sensor placed. This guide covers the essentials; for specific cases also check the installation FAQ.

What you need

• The Tinajon Pro controller (includes solid-state relay and magnetic contactor).
• The ultrasonic sensor and its cable.
• Access to the electrical panel or a point near the pump with power available.
• Basic electrician's tools (screwdriver, wire strippers).

Mount the controller

The controller comes in a DIN rail format. You can mount it inside an existing electrical panel, or fix a length of DIN rail to any surface near the pump and clip it on there.

1. Pick a dry, ventilated spot close to the pump and the electrical panel.
2. Fix the DIN rail to the surface (or use one already in your panel).
3. Clip the controller onto the rail — no extra screws needed.

Wire the pump

The controller takes direct line power (110V or 220V — it auto-adjusts, no manual configuration needed) and drives the pump through a solid-state relay and a magnetic contactor.

1. With power cut, connect the incoming line to the controller's input terminals.
2. Connect the contactor output to the pump, following the diagram included in the box.
3. Double-check every connection is secure before continuing.

Install the sensor

The ultrasonic sensor measures the distance to the water from above, so it goes on the tank's lid or top, facing down.

1. Mount the sensor on the tank lid with a clear line of sight to the water — no obstacles between the sensor and the surface.
2. Leave at least 30 cm between the sensor and the maximum water level — closer than that, the sensor gives false readings (check the sensor's datasheet for more detail).
3. Run the cable to the controller. You can use up to 20 meters of cable without losing accuracy — use shielded cable and keep it away from high-voltage lines.
4. Connect the sensor to the controller following the included diagram.

Power it on

Restore power. The OLED screen should light up and the buzzer should beep briefly — that confirms the controller started up correctly. If the screen stays blank, check the wiring before continuing.
