Solar controllers
DeltaSol® A/AX/AX HE Solar controller
The DeltaSol® A, DeltaSol® AX and DeltaSol® AX HE controllers are the simplest solution for all differential controls. The version DeltaSol® A is equipped with an adjustable temperature difference and an antifreeze function. The version DeltaSol® AX presents an extended version which is additionally equipped with an adjustable target temperature for minimum or maximum temperature limitation. Equipped with an electromechanical relay and a PWM output, the DeltaSol® AX HE controller manages the speed control of a high-efficiency pump. The enclosed silicone sealing cord guarantees a protection against dripping water.
