Solar and differential temperature controllers

DeltaSol® M

DeltaSol M The DeltaSol® M is equipped with a multilingual menu, 9 relay outputs and 12 sensor inputs as well as a multitude of add-on functions and options, which enable the adaptation of the controller to individual solar and heating systems. The controller is equipped with an interface for communication with the RESOL ServiceCenter Software.
