Warning
This part has changed significantly since version 3.90; in particular, it has been added a possibility to set different priorities between summer and winter, and priorities for off-peak operation.
...
Lower numbers correspond to higher priorities; the number assigned can be considered as the order of activation: source with priority 1 is the first to be activated, source with priority 2 is the second and so on.
PHOTO TBD
When a source is enabled (that is, all the condition seen before are verified: block signals, enable signals, season, outdoor temperature, etc... ENABLE OR ACTIVE SOURCE?) all sources with lower priority are automatically disabled.
...
Priorities from 6 to 10 have a special meaning: they allow a source to be activated, if necessary, even when it is outside its optimal outdoor working temperature range.
PHOTO TBD
In particular, priority 1/6 should be read as: Priority 1, if the outdoor temperature is within the configured range for the source, Priority 6, if the outdoor temperature is outside the configured range for the source.
In sintesi si può affermare che se si seleziona 1/6, 2/7, ecc. significa che la priorità PRIMA della barra è applicata quando la temperatura esterna è ENTRO il range di abilitazione della sorgente, la priorità DOPO la barra è applicata quando la temperatura esterna è FUORI dal range di abilitazione della sorgente.
Se si seleziona ROT A/B/C corrispondono a rotazione alle priorità 2/3/4 come indicato in tabella:
Example
To better explain the use of priorities 6 to 10, consider this very common case: a system is equipped with a heat pump and a boiler. The heat pump is used (in winter) for outdoor temperatures > 5°C, the boiler is used for outdoor temperatures <= 5°C. Both the boiler and the heat pump are equipped with a block signal; if one of them goes into block, you want the other one to switch on regardless of the outdoor temperature.
...
If ROT A/B/C are selected, they correspond in rotation to priorities 2/3/4, as shown in the table:
...
ROT A corresponds to priority: | ROT B corresponds to priority: | ROT C corresponds to priority: | |
from the 1st to the 10th day of the month | 2 | 3 | 4 |
from the 11th to the 20th day of the month | 3 | 4 | 2 |
from the 20th to the end of the month | 4 | 2 | 3 |
