7.3.1.6 Heating circuit temperature offset
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.

7.3.1.7 Heating circuit pump extended running time
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.

7.3.1.8 Screed function
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.
