Section 1
Overview
SunTouch®Control System Overview
Congratulations! On your purchase of the Pentair Aquatic Systems SunTouch® Control System - The next
generation in intelligent pool and spa control systems. The SunTouch Control System quick-access menus
helps you to setup control of your pool and spa daily operations. Your system can be easily congured to
operate in “Solar Only” mode for solar systems, “Pool/Spa” mode for shared equipment systems or “Single
Body of Water” mode for single equipment systems.
The SunTouch Control System supports the IntelliChem® Chemistry Controller, IntelliChlor® Salt Chlorine
Generator (SCG), for pool water sanitizing and IntelliFlo® Variable Speed (VS) and IntelliFlo® Variable Flow
(VF) Pump to meet all your pool and spa needs. For a complete list of the SunTouch Control System and
optional equipment, see to page 43.
Solar Mode
The SunTouch Control System Solar Mode provides automatic solar heating control using a differential
temperature control designed especially for solar-heated swimming pool, spas, and hot tubs. Also included is
solar nocturnal cooling control for optimizing heat control at night. Whenever solar energy is available, The
SunTouch Control System will automatically activate a motorized three-port solar valve and/or the optional
solar booster pump which controls the water ow direction, and pump pool water through the solar collectors.
The lter pump timer can be set so the lter pump is operating during that time of the day when solar energy
is available.
If you are using a pool cleaner booster pump for your pool, the SunTouch Control System will disable the
pump for ve minutes whenever the solar system turns on. This protects the pump from possible damage
caused by residual air within the solar panels.
Note: For information about setting up and operating the SunTouch Control System as a solar only
system, see page 5.
Pool/Spa Mode
The SunTouch Control System Pool/Spa Mode provides automation controls for pool and spa shared
equipment systems or for pool only or spa only “Single Body” systems. With the addition of two valve
actuators, The SunTouch Control System can be congured to control your pool and spa heating and ltration
schedules and additional features such as pool lights, automatic cleaners, or waterfalls.
Using the optional QuickTouch® (QT4) Wireless Remote controller you can control up to four circuits to
activate the spa circulation, and for operating three auxiliary pieces of equipment (such as lights, jet pump,
air blower, waterfall, etc.). For more information, see “Main Menu: QuickTouch (QT4) Wireless Remote,” on
page 28.
