Check the line that leads to that box for cuts or any damage which will affect the sensors readings.

Check for wire any interference sources (High voltage, motors, inverters, VFD's etc….)

Check - Meter the Power Supply or even try a different 12VDC power cube, at 500mA or more, and see if dropdown voltage AC to DC is accurate, Since incorrect voltage can discourage the logic within the device.

You Also want to meter the V+ and the VOut.  Removing the wires from these locations and the Ground and simply meter the locations.

The Voltage should be between 3 & 3.5 Volts

Try toggling off switches to equip, one at a time and see if sensors stabilize.

Try detaching sensor from its current location and put it right next to controller, see if the readings recover.

If you are using generator power - or dirty power, try powering controller from a different power source location.
