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.

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.

7.3.1.8Screed function

NOTE 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.
