n
NIGHT
This parameter is displayed if at least one circuit does not
include a room sensor.
For circuits without a room sensor:
4
NIGHT :DEC.
(Reduced): The reduced temperature is maintained
during reduced periods. The circuit pump operates constantly.
4
NIGHT :STOP
(Stop): Heating is shut down during reduced
periods. When installation antifreeze is active, the reduced
temperature is maintained during reduced periods.
For circuits with a room sensor:
4
When the room temperature is lower than the room sensor set
point: The reduced temperature is maintained during reduced
periods. The circuit pump operates constantly.
4
When the room temperature is higher than the room sensor set
point: Heating is shut down during reduced periods. When
installation antifreeze is active, the reduced temperature is
maintained during reduced periods.

Function 0-10 V
This function controls the boiler using an external system that
includes a 0-10 V output connected to the 0-10 V input. This control
imposes an instruction set temperature on the boiler. It will be
necessary to ensure that the parameter
BOILER MAX
is higher than
CONS.MAX 0-10V
.

x
Voltage at input
y
Boiler temperature
If the input voltage is less than
VMIN/OFF 0-10V
, the boiler is off.
The boiler temperature setting corresponds strictly to the 0-10 V
input. The secondary boiler circuits continue to operate but have no
impact on the water temperature in the boiler. If using the 0-10 V input
and a secondary boiler circuit, the external regulator providing this
0-10 V power supply must always request a temperature at least
equal to the needs of the secondary circuit.
