For special applications this function offers the possibility to admit 
the heating curve of the direct heating circuit with a constant 
offset value. The demand value plus the offset value is 
transmitted to the heat generator. 

The displacement of the heating curve is carried out in parallel 
with the flow temperature. 

 

To ensure the desired setpoint temperature for remote heating 
circuits as well.

The heating circuit pump ceases operation if there is no heat 
demand from the heating circuit. Safety switch-off of the heat 
generator is prevented. 

While the pump extended running of a mixed heating circuit pump 
(MC-1 and MC-2 only) is active, the mixed heating circuit 
continues to adjust its setpoint without forwarding a demand value 
to the heat generator.

This function is not active if the heating circuit control is used as 
constant control (CC). 

If the screed function is active for a direct heating circuit, only 
requests of this heating circuit are forwarded to the heat 
generator. Requests of other heating circuits are suppressed.  

 

Activation of the screed function for a non-mixed heating circuit 
only functions at the direct heating circuit of the central device 
with address 10 (CD1 - DHC) and only if no other central devices 
are present on the bus network.
