Intermediate heating operation
This function can only be activated in systems Anl 2.0.0, 2.1.0 and 2.2.0.
The function block setting DHW–CO4–07 = ON causes heating operating in heating circuit
HC1 to be restarted for ten minutes after 20 minutes priority. The setting DHW–CO4–07 = OFF
gives the storage tank charging unlimited priority over the heating operation in the UP1 heating
circuit.
Note:
The
Intermediate heating
and
Parallel pump operation
functions cannot be configured
simultaneously. When DHW–CO4–06 = ON is configured, DHW–CO4–07 = ON cannot be
selected and vice versa.

Parallel pump operation
This function can only be activated in systems Anl 2.1.0 and 2.2.0.
The function block setting DWW–CO4–06 = ON, the heating pump UP1 remains switched on
during DHW heating unless certain operating situations occur. These situations include, for ex-
ample, those when the current flow temperature demand of the pump circuit is lower than 'Min.
flow set point in heating circuit for parallel pump operation'. In this case, the controller applies
priority operation with intermediate heating. Once a parallel pump operation cycle has been
activated and the time for 'Delay of cancelation due to system deviation' has elapsed, system
deviations greater than 5 °C cause the controller to suspend parallel operation for ten minutes
and to apply priority operation.
By setting 'Delay of cancelation due to system deviation' to 0 min. leads to a parallel operation
once initiated to remain regardless of a deviation.
Note:
The
Intermediate heating
and
Parallel pump operation
functions cannot be configured
simultaneously. When DHW–CO4–06 = ON is configured, DHW–CO4–07 = ON cannot be
selected and vice versa.
