Control Functions

Language selection occurs after the controller is started. You can 
then select the controller type: 

•  SDC (heating controller)  

or 

•  DHC (district heating controller) 

"SDC - DHC" appears on the top line. The selection option "SDC" 
or "DHC" appears at the bottom right. The controller type depends 
on the relay equipment or the set type/max code. 

Switching is only possible with relay equipment for which DHC 
types exist. This is not the case with any others. 

Switching the setting is also possible via a special system 
parameter. 

The type code setting is identical for both versions, i.e. the type 
code numbers of SDC equipment correspond to those of DHC 
equipment.  

Reducing a controller to a heating circuit expansion via type code 
(21 or 22) functions only with a presetting to controller type SDC. 

Each controller type covers a specific hydraulic diagram in its "as 
supplied" condition. Depending on the configuration variants there 
is also the possibility of adapting the system by means of further 
parameter settings to hydraulic diagrams differing from the 
standard hydraulic system. 

With parameter 01 in the "Hydraulics" menu a preselection can be 
made from the hydraulic schemes collection. The corresponding 
inputs and outputs are assigned automatically according to the 
hydraulic diagram and can be altered if necessary. The 
associated system schematics are available in the hydraulic 
schemes collection.

The selected functions can be assigned only once and are then 
no longer callable in other variable inputs. If an input function is 
absolutely necessary for a corresponding output function with 
regard to the variable outputs, no selection is possible.
