B.3 ABOUT THE CONTROLLER

 

The Temperature Difference Controller LTDC facilitates efficient use and function control of your solar or heating system. The device is impressive 
most of all for its functionality and simple, almost self-explanatory  operation. For each step in the input process the individual entry keys are as-
signed 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 LTDC can be used as a solar controller for the various system variants illustrated and explained under “D.2. - Hydraulic variants / systems” on 
page 13.

Important characteristics of the LTDC :
     - 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.
     - Individual configuration of special functions
     - Extensive setting menus with explanations
     - Menu block can be activated to prevent unintentional setting changes
     -  Resetting to previously selected values or factory settings
     - A wide range of additional functions are available.

The controller is available 4 different versions.  See page 3.
