Solar and differential temperature controllers
Solar controller DeltaSol® C HE
The RESOL DeltaSol® C HE is designed for the control of a high-efficiency pump in standard solar thermal systems. The control is effected via a PWM output. The controller offers functions such as speed control, heat quantity measurement, tube collector function and a graphical balancing function.


(pump speed control):
(e.g. heat exchange):
