27. CONNECTING THE EXTERNAL PROBE
The boiler is prearranged for connection of an external probe (supplied as accessory).
For the connection, refer to the figure below (terminals 3-4) and the instructions supplied with the probe.
When the external probe is connected it is possible to adjust the heating delivery temperature in two different ways.
If the climate controller is installed in the boiler (section 18.1), the adjustment of the heating delivery temperature depends
on the
K REG
curve (graph 3), manually set using the b/-
.
If the climate controller is installed on the wall (section 18.2), the adjustment of the heating delivery temperature is auto-
matic. The electronic management automatically sets the correct climate curve, depending on the external temperature
and on the ambient temperature found (see also section 20.1).
IMPORTANT:
the value of the delivery temperature
TM
depends on the F16 parameter setting (section 21). The ma-
ximum settable temperature may 85° or 45 °C.
