It consists in a resistance which varies according to outdoor
tempera ture.
It allows the integrated P.C.B. to vary the system ow temperature
in relation to outdoor temperature.
External probe (B4)

It is a resistance varying according to the primary circuit ow water
temperature.
It is also used as limit thermostat (90 °C).
Flow probe
(B1)
NTC Probe
10 kΩ 25 °C
It allows for the P.C.B. to be able to read the ow temperature
from the storage tank.

It is a switch with clean contacts closing a circuit (low voltage) on
the integrated P.C.B. enabling central heating operation when
ambient temperature is less than desired.

It sends signals to the board of the various operating status buttons, program setting
information and reset, as well as signals regarding domestic hot water temperature and
heating regulations (times, room temperature, error codes etc...).
Using the Super CAR it is possible to indierently vary some settings of the boiler control
