Calculating the Water Change Volume
Change for Simple
8
The volume can be calculated by multiplying the width and length
of your tank and the distance between the pyramids of the two
sensors.*
For example, a tank is 18 inches in length and 17 inches in width. If
the distance between the two sensors is 3 inches, the water change
volume is approximately 4 gallons.

18” (L) X 17” (W) X 3” (H) = 918 cubic inches (around 4 gallons)**
* The water volume might be inuenced by factors such as the
speed of return pump.
**231 cubic inches = 1 US gallon

*During water change process, pressing can stop the process
and return to the previous AWC MANUAL/AUTO setting page. Also,
ATO is forced to be turned off if its previous status is on and at the
same time the controller gives a ve-second audible and visual alert
( ashing).

Quick Security Technology (QST)
Change for Simple
13
Smart AWC Duo uses QST for real-time protection against any failure
situation.*
QST can detect the malfunction of the sensor, the controller, and the
empty reservoir to avoid the pump running dry. The controller will
give an audible and visual alert when any one of the following
situations occurs.
For ATO: Any lling time is 6 times longer than the rst lling time.
For example, if the rst lling time is 10 sec, the controller will give
an alert when any lling time is over 60 sec.
For AWC: Any draining time or lling time is 3 times longer than
the rst one.**
For example, if the rst draining or lling time is 20 sec, the
controller will give an alert when any draining or lling time is
over 60 sec.
*No security time control for the rst lling and draining.
**AWC lling time including the lling occurring during 3-minute
balance period.
How to Reset / How to Clear QST Memory?
Press for at least 8 seconds until the display goes black can clear QST
memory and go back to factory setting. After reset, please unplug
and plug the power cable back in.

Power Outage Security Measures
Change for Simple
14
1. When the power outage occurs during the water change process,
the process will be delayed for 1 minute after restoration of power
and then resumes. The pump icon will ash during the delay.
2. When the power outage occurs during the countdown, the timer
will pause during power outage.* It will retain the record and
resume after power outage automatically.
Specifications
1. Power Input : 100-240 VAC 50-60 Hz
2. DC Pump :
• Head : 8.2 feet (250 cm)

Notice
1. Please read the manual in detail before installation.
2. If using another ATO instead of the built-in ATO, please turn off
