Optg action return diversion
(4796)
The function can either be used as return temperature increase or as return tem-
perature decrease.
Temp decrease:
If the return temperature of the consumer is higher than the tem-
perature on the selected sensor (prog. no. 4795), the lower part of the storage
tank can be preheated with the return. The return temperature drops even lower
with this, which, for example with a condensing boiler leads to a higher efficien-
cy.
Temp increase:
If the return temperature of the consumer is lower than the tem-
perature on the selected sensor (prog. no. 4795), the return can be preheated by
redirecting over the lower part of the storage tank. In this way, for example, a re-
turn reheating can be implemented.
Full charging
(4810)
The function
full charging
makes it possible that the released heat source is first
switched off, despite automatic heat source block if the buffer storage tank is
fully charged. During active function the heat source parameterized for the fully
charging function is first switched off, if the fully charging setpoint is reached or
the boiler must be switched off because of burner control.
Off:
the Full charging function is switched off.
Heating Mode: The full charging is active if the automatic heat source block
blocks the heat source during valid heat request based on the buffer temperatu-
re. If the buffer storage tank reaches the requested temperature on the sensor pa-
rameterized for the full charging function, the function is ended.
Always:
The full charging is active if the automatic heat source block blocks the
heat source during valid heat request based on the buffer temperature or the
heat request is invalid. If the buffer storage tank reaches the requested tempera-
ture on the sensor parameterized for the full charging function, the function is
ended.
Full charging temp min
(4811)
The buffer storage tank is charged minimally to the set value.
Full charging sensor
(4813)
With B4
For the full charging function the buffer storage tank sensor B4 is consi-
dered.
With B42/B41:
For the full charging function the buffer storage tank sensor B42,
if not available buffer storage tank sensor B41, is considered.
DHW-storage
Charge push forward time
(5011)
If the setting
several times/day
is selected under prog. no. 5010, the DHW release
is pushed forward by the set charge push forward time compared to each heating
circuit allocation and kept during the heating circuit allocation.
