Sorel STDC Version 1


Sorel Small Temperature Difference Controller


Made in Germany by Sorel 


Single circuit controller for basic systems with 1 storage. This Listing is for Sorel STDC-V1.


The Temperature Difference Controller STDC facilitates efficient use and function control of your solar or heating system. The device is impressive most of all for its functionality and simple, self-explanatory operation. For each step in the input process the individual entry keys are assigned to appropriate functions and explained. The controller menu contains headwords for the measured values and settings, as well as help texts or clearly-structured graphics. The STDC can be used as a temperature difference controller for the various system variants.


Important characteristics of the STDC : 

 - Depiction of graphics and texts in a lighted display 

 - Simple viewing of the current measurement values 

 - Analysis and monitoring of the system by means of statistical graphics,etc. 

 - Extensive setting menus with explanations 

 - Menu block can be activated to prevent unintentional changes of settings 

 - Resetting to factory settings
