Safety Notice
Important Safety Instructions
When installing and using this electrical equipment, basic safety precautions should always be
followed, including the following:
READ AND FOLLOW ALL INSTRUCTIONS.
WARNING - To reduce the risk of injury, do not permit children to use this product unless
they are closely supervised at all times.
WARNING - Water in excess of 100 degrees Fahrenheit may be hazardous to your health.
A green colored terminal (marked “G”) is located inside the high voltage compartment of
the LX-220 Solar Control. To reduce the risk of electric shock, this terminal must be
connected to the grounding means provided in the electrical supply service panel with a
continuous copper wire equivalent in size to the circuit conductors supplying this
equipment.
SAVE THESE INSTRUCTIONS.

Introduction
The LX220 Control System is a basic differential temperature control designed especially for
solar-heated Swimming Pool applications. Whenever solar energy is available, the Control will
automatically activate a motorized three-port Solar Valve and/or a Solar Booster Pump.
Remember to set the filter pump timer so that the filter pump is operating during that time of the
day when solar energy is available.
If the Swimming Pool utilizes a pool cleaner booster pump, the Control will optionally disable
the pump for a period of 4 minutes whenever the solar system turns on. This protects the pump
from possible damage caused by residual air within the solar panels.
Package Contents
The LX220/2TX Solar Valve Control System includes the following components:
LX-220 Solar Control
CVA-24T Valve Actuator
PTV-2TS 3-Port Valve
TS-5T Temperature Sensor (2 qty.)
Note: The System is also available without Valve and Valve Actuator. Order LX220/B Solar
Booster Pump System.
Tools Required: 5/16” Drill for Water Sensor. Cable for Solar Sensor.

Plumbing Requirements
Plumb system in accordance with recommended hydraulic schematic.
2” dia. plumbing is advised to ensure maximum flow of water through the solar panels. A solar
booster pump should be added if panels are installed at a very high elevation.
It is recommended that the solar panels are mounted in a way that gravity will allow draining
whenever the filter pump is not on.
For systems with glazed panels, damage can occur from overheating if the filter pump is still
running after the solar has turned off. To enable glazed panels to automatically drain whenever
the solar turns off (even if the filter pump is still running), a 1/2” motorized Solar Drain Valve
(model HW-5B) should be plumbed from the solar feed line, through a check valve, to a zero
psi point (such as pool fill line or jet air intake).

Installation Instructions
Solar Control
Select a convenient location to mount the Control, making sure that the location is greater than
5 feet from the Pool or Spa and no further than 15 feet from the Solar Valve. Wall-mount the
Control, using appropriate screws through the threeexternal mounting pointslocated on the side
of the enclosure.
Valve Actuator
Mount Valve Actuator to solar valve using the 4 mounting screws provided. Run cable to solar
control. Loosen LOCK SCREW on service panel of Solar Control, and swing open to expose
the high voltage and low voltage compartments. Insert Valve Actuator cable through hole on
bottom left side of Solar Control, and plug into circuit board at VLV1 socket.
6Compool Lx220
Water Sensor
Select a convenient location to mount the Water Sensor in the plumbing system between the
filter pump and filter. Drill a 5/16” dia. hole in one side of pipe, and install one of the
Temperature Sensors (included) in accordance with instructions provided. Run 22 gauge 2-
conductor cable (included) between the Sensor and low voltage compartment of the Solar
Control. Use waterproof connectors (provided) to connect Sensor to cable. At the Solar Control,
strip insulation 1/4” and connect to the circuit board at WATER SENSOR screw terminals.
Solar Sensor Install the other Temperature Sensor at the solar panel array, or any sunny location.
WARNING: DO NOT DRILL HOLE AND CLAMP SENSOR INTO SOLAR PIPE. For
glazed panels, install Sensor between collector and glazing. Run 2-conductor cable between the
Sensor and the Solar Control. Use waterproof connectors (provided) to connect Sensor to cable.
At the Solar Control, strip insulation 1/4” and connect cable to the circuit board at SOLAR
SENSOR screw terminals.
High Voltage Wiring
The high voltage wiring section is located behind the service panel in the lower right side
compartment of the Solar Control. Holes are provided on bottom of enclosure for conduit
mounting. The Solar Control can be connected either to 115VAC or 230VAC. The Solar
Control should be wired so that it gets continuous power (connect to Line-Side of Time Clock
or directly to sub-panel).

Pool Cleaner Protection
Recommended for use in pool systems which utilize a “boosterpump” pool cleaner. This feature
automatically turns off the pool cleaner pump for a few minutes whenever solar is initiated. This
will protect the pump from damage caused by air in the solar panels at system start-up.
Install Relay Kit (model RLY-SC) at the Solar Control in accordance with instructions
provided, and plug low-voltage connector onto circuit board at SWP Socket. Using wire nuts,
connect Black wires to Load connections of Pool Cleaner Time Clock, and connect Red wires
to the Pool Cleaner Pump.
Solar Booster Pump Control
If a solar booster pump is being used, install a Relay kit (model RLY-SC) at the Solar Control
in accordance with instructions provided.
Plug low-voltage connector onto circuit board at PMP Socket. Using wire nuts, connect Black
wires to 115VAC or 230VAC Line Voltage, and connect Red wires to the Solar Booster Pump.

Second Valve Actuator
It is possible to control a maximum of two Valve Actuators. Plug the second Valve Actuator
into VLV2 socket.
System Start-up Apply power to the system.
Place the WATER FLOW TO PANELS Switch in the “OFF” position. The POWER ON and
POOL CLEANER DELAY EXPIRED Lights should come on.
If pool cleaner protection has been added to the system, the pool cleaner pump motor should be
activated whenever the pool cleaner timer is on. Momentarily turn pool cleaner timer on and off
to check that the motor is operating correctly.
Check that Solar Valve is in “solar bypass” position, diverting water away from solar panels. If
Solar Valve is staged incorrectly (ie: diverting water to the solar panels), reverse switch on back
of Valve Actuator (change from ON1 to ON2, or vice-versa). The Valve Actuator will
automatically rotate to the correct position.
Place the WATER FLOW TO PANELS Switch in the “ON” position. The POOL CLEANER
DELAY EXPIRED Light will turn off, and the SOLAR ON Light will come on. Check that
Solar Valve has rotated from the “solar bypass” position to the “solar” position, diverting water
through the solar panels.
Place the WATER FLOW TO PANELS Switch in the “AUTO” position.
The system is now ready to be operated as desired.
