JBJ Automatic Top Off (A.T.O.) System Water Level Controller Information


Product Manuals & Documentation

Tired of lifting heavy buckets to refill sumps or tanks due to evaporation?

There is finally a professional grade product that automates refilling evaporated water. The All-New A.T.O. (Automatic Top Off) device is the most advanced water level controller system on the market. Lifting heavy buckets and spilling water is now a thing of the past. Maintaining stable salinity and specific gravity are no longer a problem since the A.T.O. will refill as soon as the water level drops. The A.T.O. will keep your reef tank parameters consistent, ensuring an optimal environment for your tank inhabitants.

Advanced Features

Float Sensors
The A.T.O. is equipped with (2) float sensors that activate within seconds when your water level drops and automatically refills your sump or tank until it reaches your desired set point. Each float sensor has been designed with an exterior guard preventing snails & hermit crabs from attaching to the sensors.

Electronic Controller Module
Our state-of-the-art electronic controller allows for (2) modes of operation with a total of (3) different set up scenarios, allowing you more choices for installation for your unique set up. Our compact controller also incorporates a visible LED panel + our innovative Audible Signal alerts when in operation mode.

Linkable Brackets
Your professional kit includes commercial grade "Linkable Brackets" that can easily be adjusted to meet your height requirements, and securely positions your float sensors. Many competing brands use inferior suction cups that are temporary that can lead to disastrous water spillage.

Pump Safety Protection
The A.T.O. automatically stops power to your return pump in you reservoir, in the event that your reservoir is low on water. This safety feature prevents pumps from running dry and failing.

Specifications:
  • Item: Water Level Controller System
  • Model: A.T.O.
  • Purpose: To automatically replenish water lost through evaporation
  • Power Supply for Pump Capacity: 2 Amps
  • Dimensions (L x W x H): 1.5" x 2.75" x 4"
  • Weight: 2 lbs
  • Water Pump: (Not Included)


Frequently Asked Questions (FAQs)

Q: How large of a pump can I plug into the A.T.O.?
A: The A.T.O. receptacle will handle pumps up to 2 amp capacity.

Q: Can the Audible Alert be turned off?
A: Yes, it can be turned off if the "Speaker Buzzer" is removed from the circuit board.

Q: Why does my A.T.O. automatically shut off after a few minutes of operation even though the water level has not reached the float sensor?
A: All A.T.O. Controllers have a factory "Float Fail-Safe" duration time period of 3 minutes and 45 seconds of operation before power to the pump is turned off. The Pump LED will glow but power to the pump will not be turned on. This feature was designed to act as a safety mechanism in the unlikely event the float sensor(s) failed or if something was to get stuck in between the sensor(s). You will have to reset the float sensor(s) to restart the controller.

Q: Can I adjust the "Float Fail-Safe" duration time period?
A: Yes, the duration time can be extended to 14 minutes of operation. (Please see instructions below on adjustment.)

Comments: This is a top notch product. I hate purchasing things for my reef as the current setup has served me well for 10 years. As everyone else I bought every bell and whistle I was told to and wasted so much money. My last ato was an old reef dose pump that worked like a champ for 10 plus years and I was sad to see it finally fail. This ato is great. You can use it in different configurations and itwill protect your pump from running dry. I like the floats and the cover around it to protect from invert interference. No suction cups is also nice. Any product still utilizing suction cups should be banned. There is an audible alarm but the way I am using it the alarm is out of the picture. You will like every aspect of this product.

Comments: This is one of the most useful pieces of equipment I have purchased for my system. I love not having to add water manually daily or twice a day. My one complaint is that sometimes it will allow too much water I evaporate before turning on and it causes the pump to run for a long period of time without filling the tank. I just have to restart the ATO and it works again.

Comments: So far this has been a great product! I actually like the auto turn off fail safe. When my top off bucket is pumped empty and the unit keeps pumping but no water comes out it shuts off after 3 minutes! (can be adjusted to 14). Genius! The only reason this product does not get 5 stars is because the power cord and the sensor cord are on either side of the plug in for the pump and too close to allow me to plug in the pump I currently had. (it had a larger transformer not a normal plug). So I bought a new pump as well. All around a great product!

Simple ATO

Comments: Great little ATO device. Easy to set up and maintain. Does what it should do, with a couple bells and whistles like an adjustable emergency pump shut off timer, float placement options(both in sump, or 1 in sump an 1 in ato water container), and fill alarm on/off switch. Highly recommended!
