INTRODUCTION
The AquatiControl Technology (ACT) Model ELC-800r 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 instructions can be found on the following pages of this
manual. Line drawings for each sensing configuration can be found on our website at
www.aquaticontrol.com.
The ELC-800r should ship with the following contents:
(1) Control unit
(1) Sensing Unit
Standard Well
Sight Glass
Wet Well
Surge Tank

INSTALLATION
The controller and sensing unit should be securely mounted on a sound surface.
The controller should be mounted within five 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 sensing unit should be at the normal
operating water level of the pool. An isolated static water line from the pool to
the sensing 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 included 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 ½” 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 ½” 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 (sensing unit and sight
glass 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 three 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 (a wiring diagram is 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-
800r. 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-800r unit will actuate up to a 2” solenoid valve with a 24 VAC, 10 watt
(max) supply, without the use of an auxiliary relay. AquatiControl Technology
recommends an anti-water hammer or slow close solenoid valve. The power and ground
cables should be directly connected to the ELC-800r terminal strip.
Refer to www.aquaticontrol.com for a full line of solenoid valves.
CONNECTING LOW WATER FEATURE
The ELC-800r has a low water feature that incorporates a NC/NO relay located
inside the control unit. The relay is used to interrupt the power to a pump in case of a low
water situation or it can be wired to an alarm, light or sounder.
PUMP CUT-OFF
The ELC-800r has incorporated a 24VAC output and relay to allow for a
low water setting to shut off a circulation pump in a low water situation. A
24VAC contactor in line with the pump is needed and not supplied. Also
required is another sensing unit that will suit the needs of the body of
water.
The second sensing unit should be placed at chosen low water level and
adjusted. Once the sensor and contactor are in place and wired they can be
connected to the ELC-800r using the provided wiring diagram.
ALARM/LIGHT/SOUNDER
The ELC-800r has incorporated a 24VAC output and relay to allow for a
low water setting to turn on an alarm, light, or sounder in a low water
situation. A separate 24VAC alarm, light or sounder is needed for this
feature. Also required is another sensing unit that will suit the needs of the
body of water.
The second sensing unit should be placed at chosen low water level and
adjusted. Once the sensor and alarm, light, or sounder are in place and
wired they can be connected to the ELC-800r using the provided wiring
diagram.

OPERATION
Once installation has been completed as described on the previous pages, open the
water supply valve to sensor unit. If the water is not up to ideal level in the pool,
manually adjust the water level to that point.
After level is set and water is at normal operating water level, it is time to power
the control unit. Plug the unit into the 120 VAC, 60 Hz electrical outlet then proceed to
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 the user know it is on and ready.
Once power is applied to the controller there are settings in the menu that can be
changed. The user can scroll through the menu by pressing the select button. Options can
be changed using the up and down arrows.
FILL ON DELAY (time between sensor not sensing water and fill solenoid opening)
Fill on delay can be set from 15 seconds to 99 seconds.
DEFAULT: 15 seconds
MAX FILL TIME (maximum time solenoid valve is allowed to stay on per fill cycle)
Max fill time can be set from 20 minutes to 240 minutes, or continuous.
DEFAULT:30 minutes
FILL OFF DELAY (time solenoid stays on after sensor begins sensing water)
Fill off delay can be set from 2 seconds to 99 seconds.
DEFAULT:5 seconds
LOW WATER DELAY (time required before low alarm is triggered)
Low water delay can be set from 10 seconds to 99 seconds.
DEFAULT:15 seconds
LOW WATER ALARM RESET

ROUTINE MAINTENANCE
AquatiControl Technology’s Model ELC-800r 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 normally good for thousands
of on and off switches. 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 distributors and the factory.
