Which sources to enable at any given time depends on the following factors:

Do not use the Auxiliary sensor!
...
If it is used to control Enabling, besides the above points being true (the source must be in the season and outdoor temperature ranges in which it is enabled, it must have the correct priority, the enable signal if present must be entered and the block signal not entered), the sensor used must be in the water set point range set in the "Set point Control" section (in the case below in the range 20-55°C):PHOTO TBD
...
The source will be enabled as long as the sensor is > the minimum set - delta (in the example 20°C - 5°C, so up to 15°C) and as long as it is < the maximum set + hysteresis (in the example 55°C + 5°C, so up to 60°C).
...
If it is used to control Activation, the source must still be enabled, otherwise it will never be activated (the source must be in the season and outside temperature range in which it is enabled, it must have the correct priority, the enable signal if present must be entered and the block signal not entered), but its activation or deactivation depends only on the set point being reached.PHOTO TBD
...
Activation and deactivation of the source are linked only to the set point arriving from the circuits (the highest in winter and the lowest in summer, including offsets). If the set point was higher than the maximum or lower than the minimum, it would be cut off, so if a set point of 70°C arrives from the circuits, a maximum of 55°C is set to the source.
So, assuming a set point of 55°C36°C, the source will activate if the sensor < 55°C 36°C and deactivate when the sensor > set point + hysteresis (so 51°C39°C).
The source will always remain enabled regardless of the temperatures reached by the sensor. In the above case, even if the sensor is at 14°C30°C, the source is always enabled.
The auxiliary activation output, on the other hand, is activated if the sensor < set point – delta (so in the case under consideration below 52°C 31°C = 55°C 36°C -3 5 °C) and is deactivated when the sensor > set point – delta (so in the case above 52°C31°C).
Activation and Enabling without Associated Sensor
...
In the last section at the bottom of each source there is a summary which at a glance shows whether the source is enabled, active, in cooling mode and whether the external and water temperatures are within the source’s enabling ranges:PHOTO TBD
...
There is also a comparison between the desired temperature coming from the circuits (set point) and the temperature of the sensor used, if present (Current Actual Temperature).
The current speed Actual Output corresponds to the set point that would be sent to the source if a 0/10V set point output were connected.
