OUTDOOR RESET MODE
Adjust the set-point temperature according to the outside temperature
This mode allows modulating the boiler output set-point temperature as a
function of the outdoor temperature. The outdoor temperature value comes
from a temperature sensor connected to the boiler controller.
If the outdoor sensor is not connected or if its circuit is open, an alarm signal
will be displayed on the display (SE). The boiler temperature set-point will
become the set value at
STPT Min T. Outdoor
