DeDietrich Diematic iSystem User Manual

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.
n
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 command
imposes to the boiler a temperature or power setpoint. Be sure that
parameter BOILER MAX is set higher than CONS.MAX 0-10V if the
control is done by temperature.

Boiler temperature or sliding output
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.
