SDC / DHC

Control Functions

 

 

6.5Switching from SDC to DHC

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.

6.6Selection of hydraulic parameter presettings

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.

6.7The variable inputs and outputs of device series SDC/DHC 43

Variable inputs 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.
