Check it will suit your tank height clearance
A good and simply set up device if you read the instructions carefully.
A few issues . To maintain it's accuracy you really need around 500mm of clearance between the highest water level and the sensor/transmitter. This is quite a lot and much more than most tanks which try to limit wasted head space.
Secondly it has a sensor send time of around every 20-30seconds, maybe more so. When you set it up, be patient and wait for enough time for the transmitter to send it's next signal and then the receiver/display will refresh the screen properly.
To reset the levels, press SET and ALARM buttons for 5 secs. Instructions buried in the text...
