, 
Solar controller with two/three sensors,switches the pump on when there is heat to be recovered from the solar collector.
Controller has large LCD display that continuously shows the temperature in the tank,sensor positions,pump position and direction.
Solar collector temperature displayed at the press of a button.
Controller has frost protection ,is used as a back up to a frostvalve.
For reliable protection against frost, a closed loop setup with antifreeze mix would be best, please don't use car antifreeze as it is toxic.
Controller can be programmed for temperature difference circulation or a ring main 3 section time function.
Suitable for 2/3 kw element (3 kw requires relay) to be installed.
Unit has multiple safety features.Low power consumption.
Controller can help extend anti freeze life when used in aclosed loop.
