SolarTouch®Solar Control System Installation and User’s Guide
Introduction
The SolarTouch®Solar Controller system consists of a four button controller, a valve
actuator, a positive sealed diverter valve and two temperature sensors (used for water
and solar). SolarTouch solar controller maximizes available solar heat by monitoring
the temperature of both the solar collectors and the pool water. When the pool calls
for heat, and solar is available (collectors are in energy-receiving mode), the controller
automatically diverts the water flowing between the pool’s filter and gas heater or heat
pump and circulates the water through the solar collectors. The SolarTouch solar controller
supports IntelliFlo®and IntelliPro®Pumps. For more information, see page 11.

General Features
• ViewCurrentWaterandSolarTemperature: In normal operating mode
the main screen displays the current WATER temperature and TARGET
temperature. The display also indicates if Solar Heat is on or off. Press the
Enter button to view the current Water and Solar temperatures.
• EasyTemperatureAdjustmentControls:From the SolarTouch controller
control panel you can easily set the desired target temperature setting from
the Heating and Cooling menus. To set the water target temperature, press the
Less (Down arrow) button or More (Up arrow) button to lower or raise the set
temperature to the desired level.
• NocturnalCooling:The SolarTouch controller provides automatic nocturnal
(nighttime) cooling during night time hours for pools that overheat in hot
climates. When enabled, SolarTouch controller circulates relatively warmer
pool water to the collector panels when the collector temperature and the
pool temperature is hotter than the high limit setting. This process cools the
pool water over time. Circulation will stop when the collector temperature is 3°
(default) less than the pool temperature or the pool temperature is cooler
than the high limit setting. For more information, see page 7.
• FreezeControl(AdvancedMenu): When the water temperature and the
solar sensor temperature falls to 40° F (4° C) or below, the pool/spa water is
automatically circulated through the system to prevent freezing. When the solar
temperature sensor and or the water sensor reaches 42° F (6° C), or above,
freeze protection will stop. In mild climates, freeze protection can help prevent
solar collector damage. If an IntelliFlo or IntelliPro pump is being used, be sure
that the pump provides sufficient RPM/GPM flow so the entire solar array is
properly protected. In climates where prolonged freezing temperatures occur,
freeze protection is not recommended. In the event of a power failure, solar
collectors are not protected against freezing conditions. For more information,
see page 8.
• UsingIntelliFloorIntelliPropumpsfordailyltering: When using an
IntelliFlo or IntelliPro Variable Speed or IntelliFlo VF Pump connected to
SolarTouch controller, an external 24 hour time clock for daily pool filtering
is not required. These pumps have built-in programs to schedule daily pool
filtering.

TARGET Temperature and if SOLAR HEAT, NOCTURNAL COOLING or FREEZE is ON
or OFF. Press the Enter button to view the current water and solar temperatures. Degree
units are displayed in either Fahrenheit or Celsius (see Advanced menu, page 5).
Effective solar heat depends on the solar and water temperature and the start and stop
differentials, then SolarTouch controller will rotate the positive 3-way valve and turn on the
solar booster pump or increase the RPM’s if an IntelliFlo®or IntelliPro®Pump is present.
This allows the water to flow to the solar collectors.
The solar roof sensor must be 6° higher than the water temperature. The pump must be
ON for a few minutes for operation. When the roof sensor and the water temperature are
within 3° of each other, solar heat will switch off. The solar temperature start and stop
differential settings are factory set at 6° and 3°. These differential settings are adjustable
in the Advanced Menu settings. Refer to your solar service professional for the optimum
setting.

Using IntelliFlo®and IntelliPro®VariableSpeedPump
The SolarTouch®Controller communicates with the IntelliFlo or IntelliPro Variable
Speed Pump via a two conductor RS-485 communication cable (P/N 350122) which
is connected to the COM PORT on the SolarTouch controller circuit board (see
wiring diagram on page 19). When using a Variable Speed pump with SolarTouch
controller, set the desired speed at the pump from the Ext. Ctrl.* Program 2-4 (speed
buttons 2-4) menu options. Ext. Ctrl. Program 2 (speed buttons 2) is assigned for
solar heating and cooling. Ext. Ctrl. Program 3 (speed buttons 3) is assigned for
freeze control. Ext. Ctrl. Program 4 (speed buttons 4) is assigned for Solar Hold.
IntelliFlo®and IntelliPro®pumps also support 8 internal programmed schedules (time
clocks) for daily filtering schedules. (*) Note: Older IntelliFlo/IntelliPro 4x160/
VS-3050 pumps do not have a control panel display and do not display “Ext
Ctrl.”
IntelliFloandIntelliPro4x160/VS-3050Pump(Program2,3&4)Overview
Also see “Solar Hold Feature for Heating and Cooling” on page 6.
Early models of the IntelliFlo and IntelliPro 4x160/VS-3050 pumps do not have a built
in programmable scheduler (time clock) function, External Controls or LCD display
on the pump. The SolarTouch controller assigns and controls the pump’s Program
2 (Speed 2 button) for solar heat/cooling, Program 3 (Speed 3 button) for freeze
protection, and Program 4 (Speed 4 button) for Solar Hold (see page 6). When the
pump is used as the pool filter pump, the pump must be wired to an external time
clock. When the time clock turns on the pump, Program 1 (Speed 1 button) is used
for daily filtration. The LED indicator above the Program 1 (Speed 1 button) must be
illuminated before the time clock turns off. For the external time clock and the 4x160
pump to operate Program 1 (Speed 1 button) for daily filtration, please take note of the
following:
• Time clock turns the pump on and off for daily use.
•Set Speed 1 button (RPM) for everyday use and turn ON.
See page 13 for set up.
•Speed 1 must be running when time clock turns off to ensure operation.
SettingSpeed1forDailyFiltration(IntelliFloandIntelliPro4x160/VS-3050)
Set the speed (RPM) on the IntelliFlo 4x160/VS-3050 pump for the daily filtration
speed (RPM). Speed 1 must be running when the external time clock turns off. This will
ensure when the next program start time on the time clock activates the pump, will turn
on Speed 1.
SolarOverride-(OnlyUsingIntelliFloandIntelliPro4x160/VS-3050Pump)
Seepage19forwiringdiagram)
Solar Override is located under the Utilities menu, under the Advanced menu. The
default setting for Solar Override is “disabled” from the factory. When Solar Override
is disabled the system only runs during the variable speed pumps programmed run
schedule. When Solar Override is enabled it overrides the pumps schedule and runs
anytime solar heat is available.
Important Note: For the IntelliFlo 4x160/VS-3050 pump, when the SolarTouch
controller releases control of the pump, the pump will then in standalone mode and the
pump will save the last manual speed setting. The last manual speed setting is the last
speed 1-4 button pressed on the pump. Be sure the last manual speed setting is one
you want the pump to run when the SolarTouch controller has releases control and is
in pump standalone mode.
