Seller's Description

Differential controller for swimming pool solar hot water system (NOT variable)
Supplied with 2x waterproof sensors
** Each of these Differential Controllers are built with high quality components and are thoroughly checked and tested before shipment.

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)
• Led indication when operating
• Differential range: Approx. 20°C (68°F) with Approx. 1.5°C of Hysteresis
*** After much experimentation 20°C (68°F) is an ideal differential temperature.

Supplied with 2x waterproof sensors
 
Operation:
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)
For example:
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.
 
Say the temperature of the swimming pool water is +18°C (64°F) and when the temperature of the solar panel reaches +38°C (100°F) (18°C+20°C) or greater then the pump will switch on. 
Please note: solar panels can and often do reach temperatures of about +70°C (158°F) when the sun is shining which can yield an approximate output water temperature of between +30°C (86°F) and +50°C (122°F)...and perhaps more!
 
The differential pump controller also has a manual override switch which can turn the pump on at any time and at whatever temperature.
 
Information: Model DC20-1807C. These differential pump controllers are batch processed for quality.
 
Package content:
• 1x 12vDC differential pump controller
