SunTouch Pool and Spa Control System Installation and User’s Guide

Section 1
SunTouch™ System Overview
SunTouch Control System Overview
Welcome to the Pentair SunTouch pool and spa control system - The next generation in intelligent control
systems. The SunTouch control system can be easily configured to operate in “Solar Only” mode for solar
systems, or in “Pool/Spa” mode for shared equipment systems, or single body pool or spa systems. The
SunTouch system is also compatible with the IntelliChlor® salt chlorine generator for pool water sanitizing, and
with the IntelliFlo® 4x160 variable speed pump. For a complete list of SunTouch systems and optional
equipment see to page 38.

SunTouch Solar Mode
The SunTouch Solar system offers automatic solar heating control using a differential temperature control
designed especially for solar-heated swimming pool, spas, and hot tubs. Whenever solar energy is available,
SunTouch will automatically activate a motorized three-port solar valve and/or the optional solar booster pump
which controls the water flow direction, and pump pool water through the solar collectors. The filter pump
timer can be set so the filter 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, SunTouch will disable the pump for five 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 SunTouch as a solar only system, see page 4.
SunTouch Pool/Spa Mode
SunTouch 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, SunTouch can be configured
to control your pool and spa heating and filtration 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.

Note: For information about setting up and operating SunTouch as a standard pool and spa controller
in “Pool/Spa” mode, see page 9.

Freeze Protection in Solar Only mode
The SunTouch freeze protection function is active once the optional air sensor is installed and enabled
(see page 8). Freeze protection is enabled whenever the outside temperature is 36º F or lower. When freezing
conditions are detected by the air sensor the filter pump will be switched on and water will circulate continuously
through the system. It’s important that the air sensor be permanently placed in the shade and away from windy
locations. In the event of a power failure, the system will be unprotected. Recirculating water to protect your
system from freezing is not recommended in climates where freezing temperatures occur frequently and last for
extended periods.
If you live in a location where freezing conditions occur and there is no air sensor installed
or the air sensor is not enabled, your system will be unprotected.

Schedules Menu (4/13) (Continued)
Schedule your Spa or Pool
You can set a daily start and stop time to switch the filter pump on and rotate the pool or spa valves into the
“Spa” or “Pool” position. The heater will automatically heat the spa or pool water up to the set point
temperature as set in the “Heat” menu (see page 14). If the pool has a separate jet pump or blower controlled
by AUX 1 and/or AUX 2 , these need to be scheduled separately. You can also program when to filter and
heat your pool, and switch light or auxiliary circuits on or off.
You can create schedules to automatically run equipment like pool filtration or lights. Any circuit can be set to
switch on and off on every day of the week. When a relay is switched on manually, it remains on until you
either switch it off manually, or the next time the relay is scheduled to be switched off. For example, if the
filter pump is scheduled to automatically run from 3:00 PM to 5:00 PM daily then the filter pump is switched on
manually at 9:00 PM, it will run continuously for 12 hours until the next day at 5:00 PM then switch off. The
programmed schedule will then continue from then on. Default run time for the a scheduled program is 12
hours. If you program the start and stop times the same the schedule will run for 24 hours if scheduled to run
for one day. A spa or pool program can be overridden using the Spa button (Up arrow) or set Circuit On/Off

Advanced Menu (8/13): Calibrate water, air and solar sensors
The SunTouch system includes two temperature sensors for monitoring water and ambient air temperature. An
additional air sensor for controlling solar heating systems can also be installed for solar systems. Generally,
these sensors are accurate and do not require calibration. However, long plumbing runs and water features
can cause temperatures at a body of water to be different from the temperature sensor reading. You can
manually recalibrate the sensors to adjust for this. You only need to calibrate one body of water, since the
temperature sensor is common to both the pool and spa.

Calibration
Before you start, you’ll need an accurate all weather thermometer. When calibrating the air sensor, wait until
the sensor is not in direct sunlight. For the air temperature sensor, make sure that the sensor is located in the
shade for accurate readings.

SunTouch Pool and Spa Control System Installation and User’s Guide

Circuit Functions Menu (10/13)
Assigning Circuit Functions
From the Circuit Functions menu you can assign special logic to the auxiliary relay circuits AUX 1 and
AUX 2. For example, when setting up an automatic pool cleaner pump, you could assign AUX 1 the circuit
function FLOOR CLEANER. With this "Cleaner" logic the cleaner pump would force the filter pump on, and
the cleaner pump would start after a delay of five minutes. The cleaner pump would automatically shut off
whenever the spa and/or solar is switched on.
Using AUX 3 circuit: The AUX 3 connector on the SunTouch motherboard cannot be connected to a
dedicated relay, however, it can be used as an extra assignment to control pump speeds or valve actuators. For
example, AUX 3 can be assigned to control the high speed function of a 2-Speed pump or one of the four
speeds of the IntelliFlo 4x160 pump. The pump speed control can be selected/activated via a scheduled
program or switched on/off manually. Also, If VLV C is not enabled for solar, an additional pump could be
connected to VLV C for a waterfall feature and AUX 3 could be assigned to control the valve actuator to
divert water for the waterfall feature.

Freeze Protection
Freeze protection switches on a circuit if the outside air temperature sensor detects the temperature is getting
close to freezing (below 36° F). The system will switch on the circuits that have been assigned freeze
protection, and runs the circuits for every 15 minutes to stop the pipes from freezing. For pool and spa
combination the valves will rotate between the pool and spa. During this process the cleaner will be switched
off. This is especially important if there is a pool and spa combination. If freeze protection is set to both the
spa and pool circuits, the filter pump (and booster pump if installed) switches on and the pool and spa valves
alternate every 15 minutes to keep the water moving in both the pool and spa. This process continues until the
freeze condition is over.
Circuit Functions
To assign a circuit function and freeze protection: Note: The air sensor must be enabled for freeze

pump will have freeze protection. For the SPA circuit the filter pump will run and
the pool/spa valves will switch between pool and spa at 15 minutes intervals
throughout the freeze condition. For the FLOOR CLEANER circuit freeze
protection is generally not needed for pool cleaner pumps since they get water
flow from the filter pump. Just make sure that POOL has freeze protection.

about connecting the RS-485 communication cable from SunTouch to the IntelliFlo pump, refer to the IntelliFlo
4x160 Installation and User’s Guide (P/N 357269).

Freeze Protection
Freeze protection protects the pool, plumbing, and equipment against freeze damage. If the outside air
temperature sensor falls below 36° F (2° C), freeze protection is activated and the pool/spa filter pump relay is
switched on to circulate the pool water. To enable freeze protection for a circuit, see page 26. In order to use
the SunTouch freeze protection function, an optional sensor is required to monitor the air temperature. To
enable freeze protection and display the outside air temperature on the main screen, the “AIR SENSOR” must
be enabled (see Advanced Menu 8/13 on page 24). Freeze protection is enabled whenever the outside
temperature is 36º F or lower. When freezing conditions are detected by the air sensor, SunTouch will switch
the filter pump on and circulate pool water continuously through the pool and spa.
Note: If multiple AUX circuits are set to “ON,” the circuit will run the pump at the highest assigned
speed of the active circuit.

SunTouch Pool and Spa Control System Installation and User’s Guide

IntelliChlor Menu (13/13)
The IntelliChlor electronic chlorination system needs to be connected to the SunTouch system to use the
following IntelliChlor settings. While in normal operating mode (Pool, Spa mode or Spa Fill (Spillway),
SunTouch will control the chlorinator output level. When IntelliChlor is connected to the SunTouch, chlorination
levels can only be changed from the SunTouch control panel. The IntelliChlor control panel will be disabled.
The amount of chlorine introduced into the pool is determined by the amount of salt in the water, the water
temperature and the amount of time the pool operates in “Pool/Spa” mode. Note: While in “Freeze
Protection” mode, IntelliChlor will not operate during the time that the filter pump is operating. For
more information, refer to the IntelliChlor Electronic Chlorine Generator User’s Guide (P/N 520589).

SunTouch Pool and Spa Control System Installation and User’s Guide

Plumbing Requirements
It is important that the pool and spa plumbing system be in accordance with local codes and the Recommended
Hydraulic Schematics. Before starting, please review the diagrams and the following recommended guidelines:
The spa should be at or above the level of the pool.
1

If the spa is attached to the pool, provide a dam between the two bodies of water to allow the spa to
overflow into the pool. If the spa is not attached to the pool, an overflow, sufficient in size to carry a full
pump-flow, must be installed at the water level in the spa.

Plumb a three-port Intake Valve (VLV A) on the suction-side of the filter pump, so that the center port
of the valve is connected to the pump inlet. Connect the spa suction to one side of the Intake Valve, and
the pool suction to the other side.

Plumb a three-port Return Valve (VLV B) on the return-side of the heater, so that the return water will
enter the valve through the center port.
Connect the spa return to one side of Return Valve, and the pool return to the other side.

If required, install a spa makeup line (consisting of a manual gate or ball valve, for elevated spas install a
check valve) to bypass the pool return line. This will enable some of the chemically-balanced water from
the pool to cycle through the spa. The manual valve will allow the amount of bypass to be adjusted.
For systems which incorporate a skimmer, it is possible to balance the amount of suction between the
skimmer and main drain for maintenance purposes. This is easily accomplished by installing a manual
three-port mixing valve at the suction line. Plumb one port to the skimmer and the other to the main drain.
If a “non-booster pump” pressure-side pool cleaner is being used, plumb a manual three-port valve
between the filter pump and filter, with the third port plumbed to the pool cleaner line, and install a
motorized two-port Pool Cleaner Valve at this line. The motorized valve will automatically open
whenever the SunTouch activates the pool cleaner.
If a booster pump pool cleaner is being used, plumb the booster pump so that its suction-side is connected
to the pool return, after the heater, and as close to the ground as practical.

SunTouch Pool and Spa Control System Installation and User’s Guide

Plumb the solar feed and return lines between the filter and the heater. Install a three-port valve at the
feed line. Use a solar valve (P/N 263047)), to allow automatic draining of the panels.

A solar booster pump should be used when the distance to the panels exceed 200 ft., or the panels are
elevated higher than 25 ft.

Glazed solar panels require a drain valve to allow draining of the panels. This prevents damage from
overheating water. Install a drain valve at the solar feed line and connect to the pool fill line.

Equipment Location
All equipment, with the exception of the spa-side remote, must be located at least 10 ft. from the water’s
edge.

Solar Hydraulics System
Plumb the SunTouch solar system in accordance with recommended hydraulics shown below.
•

2” diameter 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 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).

SunTouch Solar System Installation
•
•
•

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 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).

SunTouch Solar System Start-Up
1. Switch power on to the SunTouch Power Center.
Note: 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.
2. 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 on and off to check
the motor is operating correctly.
3. Check that Solar Valve is in “solar bypass” position, diverting water away from solar panels. If Solar
Valve is staged incorrectly (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.
4. Check that Solar Valve has rotated from the “solar bypass” position to the “solar” position, diverting
water through the solar panels.
5. The system is now ready to be operated as desired.

Pool Cleaner Protection
Recommended for use in pool systems which utilize a “booster pump” 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.

Troubleshooting
Troubleshooting
Use the following troubleshooting information to help resolve problems that may occur when using the
SunTouch system. If by following the recommended actions you are still unable to resolve the problems, please
contact Technical Support (see page vi).

Frequently Asked Questions (FAQ)
How do I setup a two-speed pump?
A two-speed pump operates using two relays and one or more circuits. The first relay turns the pump on or
off. Assuming this is a filter pump, this circuit is controlled by the pool and spa circuits or any other circuit that
may be tied to the filter pump (such as circuits with freeze protection, etc.). The second relay (AUX 2)
switches the pump from low speed to high speed. The default condition is low speed. Up to three circuits may
be assigned to trigger the pump to high speed. However, if three relays are being used, two relays must be
located outside the SunTouch enclosure. The SunTouch enclosure which houses two relays. Note: These
circuits do not switch the pump on.
To configure a two-speed pump relay, refer to “Settings Menu: 2-Speed Pump,” on page 29. For relay location
and wiring (see page 51). The 2-Speed pump relay connector is plugged into the AUX 3 output socket on the
SunTouch motherboard.
Can I switch the heater on and change the temperature from the spa?
The heater may be switched on from the spa location using the QuickTouch wireless remote controller
(optional), see page 28 for setup details.
How do I switch on solar heating?
The system must first be configured for solar heating. Go to the “Heat” menu (see page 14) and enable
“Solar” as the heat source. Note: Do not set solar as a heat pump. Then the heating method must be
selected for each body of water.

SunTouch Pool and Spa Control System Installation and User’s Guide

Problem Solving a Solar System
SunTouch solar is not operating
Verify the circuit breaker at sub-panel is not tripped. If the 3 AMP Circuit Breaker on the on SunTouch is
tripped, it is most often due to a defective Circuit Board or Valve Actuator. Try disconnecting each one
separately to determine which one is at fault.
Solar will only operate when the solar temperature is 5° warmer than the water temperature.
Inspect the appropriate sensor cable and wire connections and replace the appropriate temperature sensor if
necessary. An ohm meter can be used to take a reading of the sensors. See table on page 68.
If the temperature sensors are not at fault, replace the SunTouch circuit board.
Water flow to panels switch does not operate the valve actuator
If the valve actuator does not operate when using the WATER FLOW TO PANELS Switch (sliding switch
between ON and OFF), either the valve actuator or the SunTouch circuit board is at fault.
First verify that the toggle switch located on the valve actuator is either in the ON1 or ON2 position.
With a voltmeter, check the output voltage of the VLV1 socket located on the SunTouch circuit board. When
the WATER FLOW TO PANELS Switch is in the OFF position, the top and middle pins should read 24 VAC.
When the WATER FLOW TO PANELS switch is in the ON position, the top and bottom pins should read
24 VAC.
If voltage readings are correct, replace the valve actuator. If voltage readings are incorrect, replace the
SunTouch circuit board.
Checking The Temperature Sensors
Disconnect temperature Sensor wires from the SunTouch circuit board, and test sensor using an ohm meter.
See table on page 68.

Testing the Solar System
To test the SunTouch in “SOLAR ONLY” mode: Set the “System Control” menu setting to “SOLAR ON”
verify the valve(s) are in the solar position. Then set the menu setting to “SOLAR OFF” and verify the valve is
in the normal recirculating pool position. If the valve(s) positions are working in reverse, toggle the valve
switches and test again.

SunTouch Pool and Spa Control System Installation and User’s Guide

Temperature vs. Resistance Data
SunTouch systems use 10k Ω thermistor sensors. When the solar sensor is disconnected from the SunTouch
system, the sensor will read 10k Ω at 77º F (25ºC). Refer to the tables on the following pages for the
resistance at other temperatures. The resistance reading for any given temperature should be accurate to
±0.5ºF. For any given temperature, the resistance reading should be accurate to ±1%. Be sure that the solar
sensor is connected to the SunTouch system before making any DC voltage measurements. The reading should
be accurate to ± 2%.
