4.6.2 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
