DHW exchange controllers

DeltaSol Fresh^® Modbus

– For manufacturers of DWH exchange modules –
RESOL offers a range of solutions for the control of DHW exchange modules. The new controller platform is equipped with an enhanced and faster control algorithm and enables the precise and energy-efficient control of the draw-off temperature. In order to achieve the best possible control quality, our laboratories run a number of dimensioning tests and check measurements. Classification of control quality is conducted on the basis of research results of the Rapperswil Institute for Solar Technology and the Institute for Solar Energy Research in Hamelin (ISFH).
