INTRODUCTION
The AquatiControl Technology (ACT) Model ELC-810 is designed to provide the
most accurate and reliable automatic water level control for swimming pools, spas,
fountains, and spray pads. All of the user-friendly features incorporated into the system
were designed with the operator in mind.
The importance of precise control of water level in relation to proper filtration and
water chemistry makes it possible to appreciate a device that will maintain levels within
+/- 1/8 of an inch. Installing the system requires basic tools and is accomplished quickly.
Installation and operating directions can be found on the following pages of this manual.
The ELC-810 should ship with the following contents:
(1) Control unit
Sensing Unit(s)
Standard Well
Sight Glass
Wet Well
Surge Tank
Deck Well
(1) Mounting Hardware
(1) Operation and Maintenance Manual
(1) Warranty Card
If any items are not found in this package, please call your closest distributor or
the factory at [phone].

INSTALLATION
The controller and sensing unit should be securely mounted on a sound surface.
The controller should be mounted within 5 feet of a 120 VAC, 60 Hz grounded outlet.
The controller can be wired up to 300 feet from sensor unit (contact ACT for
exceptions). ACT recommends mounting the controller in the most favorable
environment possible.
The standard well sensing unit is installed at the water level of the pool. The
center of the clear ½” PVC tube on the sensor unit should be at the normal
operating water level of the pool. An isolated static water line from the pool to
the sensor unit is necessary to provide stable water conditions. A valve
arrangement is provided. The valves are installed so that the operator may
maintain and clean the sensing unit.
The sight glass sensing unit is installed by attaching the unit to a balance tank
sight glass. The sensor should be mounted at normal operating water level of the
balance tank using the attached clic connectors.
The wet well sensing unit is installed in a 2” PVC pipe which serves as a still
water stand pipe from the pool. The normal water level should sit approximately
1.5” up from the bottom of the end cap.
The surge tank sensing unit is installed in the surge tank at normal operating
water level with the included clic connectors. The normal water level should sit
approximately 1.5” up from the bottom of the end cap.
The deck well sensing unit is installed at pool side. The unit has a ½” static line
sight glass inside to attach a sight glass sensing unit to, which is also provided.
The deck well is connected to the pool using a 2” static line. Conduit connection
and drain connections are also present to make installation quick and easy.
The 3 conductor extension cable provided with the system is the electrical
connection for the sensor unit to the controller. With the standard well, sight glass, wet
well and deck well, a terminal strip is provided in the sensor housing for terminating the
cable (please see wiring diagram for color connections located inside sensor box for
standard well, sight glass, wet well, and deck well applications). The other end of the
cable terminates inside the ELC-810. The interconnecting cable carries low voltage.
Local codes may require the cable to be housed in conduit.
Refer to www.aquaticontrol.com for sensing applications, drawings, and other product
information offered by AquatiControl Technology.

CONNECTING THE SOLENOID VALVE
The ELC-810 unit will actuate up to a 2” solenoid valve with a 24 VAC, 10 watt
(max) supply, without the use of an auxiliary relay. We recommend an anti-water
hammer or slow close solenoid valve. The power and ground cables should be directly
connected to the ELC-810 terminal strip.
Refer to www.aquaticontrol.com for a full line of solenoid valves.
CONNECTING ALTERNATE LEVEL SENSOR
The ELC-810 has an alternate level sensing feature that allows a surge tank to run
at two different levels. This feature is activated with a flow switch or through a signal
from the contactor on the feature pump located near the starter; and is normally used in
conjunction with spray features.
In order to setup the use of an alternate level on the ELC-810, a second sensing
application should be placed at the chosen lower water level and a flow switch, supplied
with the ELC-810, needs to be installed in the feature pump line. The second sensing
application and flow switch must be wired following the wiring diagram on page 6 of this
manual.
CONNECTING HIGH LEVEL WATER DRAIN OFF
The ELC-810 has a high water drain off feature that allows a NC/NO relay inside
the unit to be used to open a solenoid that will drain water.
In order to setup the use of the high water drain off feature on the ELC-810, a
third sensing application should be placed at the chosen higher water level and a second
24 VAC solenoid, not supplied with the ELC-810,should be used (can be a general
purpose solenoid). The third sensing application and second solenoid must be wired
following the wiring diagram on page 6 of this manual.

OPERATION
Once installation has been completed as described on pages 4 and 5, open water
supply valve to sensor unit. If the water is not up to normal operating level in the pool,
manually adjust the water level to that point.
After level is set and water is at normal operating level, it is time to power the
control unit. Plug the unit into the 120 VAC, 60 Hz electrical outlet; turn the on/off
toggle switch on the side of the controller to the ON position. The unit will go through a
self-test and beep to let you know it is on.
Once power is applied to the controller there are settings in the menu that can be
changed. You can scroll through the menu by pressing the up and down arrows. The enter
button will bring you back to the startup screen. Options can be changed by following the
directions below.
The first six screens as you scroll down through the menu are for informational
purposes. The screens give you the following information.
STARTUP SCREEN
This screen will tell you the version of code that your controller is running.
SCREEN 1
This screen will tell you what your controller settings are for Delay Time To
Shutoff and Maximum Fill Time.
SCREEN 2
This screen will tell you what your controller settings are for Manual Override
and Delay To Normal.
SCREEN 3
This screen will tell you what your controller settings are for Level Sensor Type
and Alternate Sensor Option.
SCREEN 4
This screen will tell you what the Last Fill Time was.
SCREEN 5

ROUTINE MAINTENANCE
AquatiControl Technology’s Model ELC-810 controller is completely solid state
and normally will not require any maintenance.
SENSOR UNIT CLEANING
STANDARD WELL
The ½” PVC tube on the Standard Well Sensing Unit may need to be cleaned
periodically. To clean the tube, isolate the sensor unit by closing the valve that
supplies the water to it. Remove the cap from the top of the tube and fill with a
diluted acid solution, 3 parts water to 1 part acid. A brush may be used to clean
the inside of the tube.
The valve at the bottom of the sensing unit can be opened to drain out the acid
solution. Place the solution into a container and dispose of it properly. The tube
can then be flushed with fresh water. After flushing, open the valve from the
pool. The unit is now ready for operation.
SIGHT GLASS
The Sight Glass Sensing Unit will not normally need to be cleaned.
SURGE TANK
The Surge Tank Sensing Unit will not normally need to be cleaned; however, if
the cap on the bottom of the sensing application becomes clogged with debris, it
can be unscrewed and rinsed until clean and then replaced.
WET WELL
The Wet Well Sensing Unit will not normally need to be cleaned; however, if the
cap on the bottom of the sensing application becomes clogged with debris, it can
be unscrewed and rinsed until clean and then replaced.
DECK WELL
The Deck Well Sensing Unit will not normally need to be cleaned; however,
debris and stagnant water may enter the Deck Well which can be cleaned out
being very careful not to get any water near the sensing unit or electrical conduit.
SENSOR REPLACEMENT
The proximity switch used for the control system is good for thousands of on/off
switching. Typically the sensor should be replaced every three years for year round
usage. Seasonal pools may require replacing every five years or as needed. Replacement
sensors are available from the distributor and factory for all but the surge tank sensing
units which need to be replaced in whole.
