Pentair SolarTouch Controller 521590

Solar pool heating is a smart investment. Make the most of it with the smartest, most efficient solar controller you can buy: SolarTouch automation from Pentair. Only the SolarTouch solar system gives you the precision and reliability of full digital control. Just set the digital thermostat and SolarTouch will monitor the temperature of the pool water and solar collectors. Whenever the sun offers sufficient energy for effective heating, the SolarTouch controller can open a motorized valve and send filtered water to your collectors. If temperatures drop, the system shuts the valve to keep cold water out of your pool.

Now you can control your pool temperature with the touch of a button. Just set the digital thermostat and SolarTouch will monitor the temperature of the pool water and solar collectors. SolarTouch also integrates with IntelliFlo and IntelliPro Variable Speed Pumps, so you can enjoy unparalleled efficiency, unbeatable digital precision and ease of use. SolarTouch is the smart, easy, efficient way to go solar.

System Includes:

  • SolarTouch Solar System Controller Only

SolarTouch Features:

  • Digital calibration of water and solar temperature sensors allow more precise measuring. Temperature control can be set in one degree increments.
  • Digital touch controls eliminate the imprecise settings and moving parts of mechanical dials.
  • Customers can set their pool temperature and solar temperature differentials with the touch of a button.
  • Solar valve automatically drains the solar collectors when the pump shuts off. Durable PTFE seal is maintenance-free for years of dependable service.
  • Savings up to $1,500 on your energy bills when you combine SolarTouch with an IntelliFlo or IntelliPro Variable Speed Pump.
  • LCD display gives sharp, clear readings of air and solar collector temperatures.
  • LED indicator lights confirm that SolarTouch automation is working. Service indicator LED indicates when attention is needed.
  • Motorized valve actuator is built to last with sturdy steel gears, a highly efficient low-voltage motor, service switch for flow direction and a weatherproof composite enclosure.
  • Includes nocturnal cooling and recirculation freeze protection, with filter-pump timer override. 
  • Pool-cleaner pump protection—prevents damage to your pool cleaner pump that can result from air in the solar collectors at start-up.
  • Control of a solar booster pump (not included)—for systems that require extra flow. Activated only when solar energy is available.
