Seller's Description
Supplied with 2x waterproof sensors
Specifications:
• Feed voltage: 12v DC
• Output: 12vDC 2A
• Manual override – to turn on the pump at any time and at any temperature
• Temperature range: from 0°C to 90°C (32°F to 194°F)
• Differential controller dimensions - 85x50x21mm (3.35x1.97x0.83 Inches)

• Differential range: Approx. 20°C (68°F) with Approx. 1.5°C of Hysteresis
Supplied with 2x waterproof sensors
Whenever hot water sensor is measured to be hotter than the cool water sensor by approximately 20°C, the differential pump controller switches on which then supplies 12vDC to a water pump and led comes on. The output remains on, until the measured temperature difference between the two sensors has fallen to below 20°C (68°F)
The hot sensor can be located on the output of a solar panel, the cool sensor can be located in the water or on a water pipe of a swimming pool
In this way when water in the solar panel is hotter than the pool water by 20°C or above - the 12vDC water pump will switch on.

• 2x waterproof sensors - the wire can be extended up to 15 Metres (50 feet)
• wiring diagram and user manual (English)
Additional items required:
• 12vDC brushless water pump (240 to 480 litres per hour).
• 12vDC power supply >= 2 amps but amperage dependant on water pump
