Pentair | 521592 | SolarTouch Solar System – Digital Control with 3-Way Solar Valve & Temp Sensors

The Pentair SolarTouch Solar System (Model 521592) delivers precise, fully digital control over swimming pool solar heating. Featuring a digital thermostat, LCD display, integrated 3-way motorized valve, and dual temperature sensors, this system ensures maximum efficient solar heat utilization with the simplicity of button operation. Included components enable preventative drain-down and seamless integration with Pentair’s IntelliFlo and IntelliPro variable-speed pumps for unmatched energy savings.

Key Features

• Accurate Digital Control
  Set pool and solar collector temperatures with 1° precision using intuitive digital touch controls.
  

• 3-Way Solar Valve with Motorized Drain-Down
  Automatically routes water through solar collectors when heating is effective; shuts and drains the collectors when not in use to prevent overheating or stagnation. PTFE-sealed motorized valve ensures long-term maintenance-free operation.
  

• Integrated LCD and LED Display
  Backlit LCD clearly displays water and solar collector temperatures; LED indicators confirm system status and provide service alerts.
  

• Freeze Protection & Pool-Cleaner Safety
  Features nocturnal cooling and sensor-based freeze protection. Automatically pauses pool cleaner operation when solar function initiates to prevent pump damage from air in solar collectors.
  

• Variable Speed Pump Integration
  Works seamlessly with IntelliFlo and IntelliPro pumps to optimize flow and power usage—achieving significant energy savings and solar efficiency.
  

• Durable Construction
  Housed in a weatherproof composite enclosure with rugged steel gears for the actuator.
  

• Complete System Package
  Includes control panel, 3-way solar valve, valve actuator, and two temperature sensors (one for pool water, one for solar collector).
  Warranty
  Backed by a 3-year manufacturer’s warranty.
  

Product Overview

The Pentair SolarTouch Solar System takes the guesswork out of solar pool heating. Users simply set desired temperatures—SolarTouch monitors pool and collector sensors, then intelligently directs water flow using its motorized 3-way valve. When solar gain is available, filtered water is pushed into the collectors; otherwise, the system diverts or drains them to prevent waste and potential damage.

Integration with variable-speed pumps brings unmatched efficiency, potentially saving up to $1,500 per year in energy costs. On top of that, safety features like freeze protection and cleaner-pump pausing enhance reliability and system longevity. The SolarTouch system simplifies solar management with smart automation, clear diagnostics, and robust engineering.
