how the auto water changer works!

program update on the ATU-Pro3 and 4

all units now sold have been updated to allow customer selection on the sensor type fitted - eg: infrared or capacitive

the big advantage here is that should you wish to change the sensor type selected by the ATU then it's simply a case of a sequence when powering the device

the only extra cost would be in the replacement sensor itself

this is to attempt to future proof any updates to your original purchase at minimal cost!

  • Both my Refloat items, being my AWC 75 and my ATU have been second to none, both have work extremely well, with minimal hick ups, given that l think my AWC must be about 10 years old and the ATU around 6 year’s, even then with the excellent back up with information, help, guidance, super fast response, postage of items, and spares from Gordon, has given me the ability to up date both of them myself at very minimal cost. Both items have been very helpful to me in this hobby, the AWC has saved me time, energy and my back, giving me a stress free water change to both myself and the live stock in the tank, the ATU has given me the benefits and peace of mind , allowing me to sit back and maybe top up the reservoir every two weeks or so, meaning that also there is less for the holiday cover person to do. I have updated my ATU to the latest sensor, very easily, which has proven to be a good upgrade for me. Happy tanking .
