THE ATU-PRO3 IS AS FOOLPROOF AS YOU CAN PURCHASE

Here are a few scenario's that have been reported on reef sites and what the ATU-PRO3 does if it happens.

• The float physically jams because of a snail or similar
• The float fails electrically
• The float drops into the tank
• The outlet comes adrift resulting in water outside the tank
• The reservoir runs dry (possible pump burn out}
• The pump gets jammed
• and most important R.O. reservoir "dumps" its contents into the aquarium

In every situation above only the ATU-Pro3 will shut the pump down after a time period set by yourself with the options of 5, 10, 20 or 60 seconds. - exclusive to Reefloat - NO other brand has this facility

The ATU-PRO3/4 is pre-wired and the unit is ready to use - includes:

• The programmable controller
• Supplied with infrared sensor and bracket with 2m flex
• A low voltage pump with a maximum height of 3 metres
• A 2amp power supply
• 2 metres pipe
• full installation guide

LETS SAY SOMETHING FAILS, WHAT HAPPENS?

In a nutshell it shuts down the pump so the top-up is inoperative until you come along and reset it, indication that it has shut down is via the pump LED starts flashing and the alarm sounds for 30 seconds, sounder then repeats for 2 seconds at 15 minute intervals. Reset is a simple push of the button, once to silence the alarm and twice to full reset - if the cause of the fault is still present then it will go back into alarm state

BONUS - Anti-Wave - many are familiar with the pump switching on and off every time you stick your hands in the water, or the same things happens if you have that powerful wave maker powerhead. This is addressed by a 3 second built in float delay activation, in other words the water level has to be "LOW" for 3 seconds before the pump starts, as soon as the level reaches a "HIGH" position the pump stops immediately. The distance between high and low level is not measurable by conventional means the sensor is that accurate!

BONUS - Memory - that preset time you set up stays unless you reprogam, it is not lost on power failure!
