Page 5: Introduction
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. -

Page 8: Temperature Control
Temperature Control From the SolarTouch Controller control panel you can set the desired target temperature ® setting using the Less (Down arrow) button or More (Up arrow) button. After the target temperature is reached, the solar system will automatically switch off or when solar energy is no longer available. -
Page 9: Solartouch Controller Menus (Main Menu - Advanced Menu)
SolarTouch Controller Menus ® Main Menus Use the Main Menu for everyday solar operating features and the Advanced Menu for solar utility settings. To access the Main Menu, press the MENU button. The Main Menu items are as follows: Main Menu Heating Menu Enable/Disable: [Enable/Disable] Target Temp - 40°... - Page 10 Heating (continued) Heating will start when the Start differential condition is met and the water temperature is below the Target Temp. When these conditions are satisfied heating is turned ON. Example: Water Temperature is 75° F; Target Temperature is 82° F. When the roof solar collectors temperature exceeds the water temperature by 6°...

Page 11: Cooling
Cooling The SolarTouch Controller can cool the pool/spa by circulating water through the solar ® collectors when the solar temperature is at a lower temperature than the pool/spa water (typically at night). Cooling must be enabled in the Cooling Menu. The default setting is “Disabled.”... -
Page 12: Freeze Protect
Freeze Protect When 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. If the solar sensor is placed at the solar collectors and when the temperature in the solar collector reaches 42°... -

Calibrating Sensors Control Panel LED indicator To adjust the calibration of the pool water and solar collector sensor go to: Advanced Menu > Utility Menu >Calibrate Water or Calibrate Solar Sensor Use the Up or Down arrow button to adjust the calibration of the sensor. The sensor can be adjusted up to +/-10°. -
Page 15: Error Conditions
Error Conditions Error Conditions When the control panel LED indicator is solid red, a sensor error has occurred; a blinking LED indicates an IntelliFlo Pump communication problem or the IntelliFlo Pump has ® ® been manually stopped. For sensor resistance data, see page 22. If the water or solar temperature sensor is shorted or open, heating and cooling will stop and not restart until the condition is corrected. - Page 16 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).
- Page 17 Setting Pump Speeds (IntelliFlo and IntelliPro VS Pumps) ® ® Setting the IntelliFlo/IntelliPro Variable Speed (VS) Pump speed for solar/cooling and freeze protect mode is setup in the pump’s “Ext. Ctrl” menu. Note: The IntelliFlo pump must be in “Running Schedule” mode to communicate with the SolarTouch Controller.

Page 18: Mounting The Suntouch Controller
Mounting the SunTouch Controller ® The SolarTouch Controller can be mounted on a flat vertical surface, such as a wall or post. Note: Select a convenient location to mount the SolarTouch controller and be sure the location is greater than five (5) feet from the pool or spa and no further than 15 feet from the pool/spa valve. -
Page 19: Installing Conduit And Wire To The Enclosure
Installing Conduit and Wire to the Enclosure • Use No. 14 minimum to No. 6 maximum AWG for power relay circuits depending on the power requirement. Be sure to follow all regulation safety codes for the number and size of conductors that can be installed in various sizes of conduit. -
Page 20: Grounding And Bonding To The Controller
Grounding and Bonding to the SolarTouch Controller ® Connect a ground wire from the primary electrical panel to the SolarTouch Controller ground bus bar. Also ground each piece of high voltage (120 VAC or 240 VAC) equipment that is connected to the Controller relays. The SolarTouch controller must also be connected to the pool bonding system using an 8 AWG (minimum) wire. -
