1.8 EXTERNAL TEMPERATURE PROBE
(OPTIONAL).
The boiler is designed for the application of the
external temperature probe (Fig. 1-6), which is
available as an optional kit. Refer to the relative
instruction sheet to position the external probe.
The probe can be connected directly to the boiler
electrical system and allows the max. system
flow temperature to be automatically decreased
when the external temperature increases, in
order to adjust the heat supplied to the system
according to the change in external tempera-
ture. The external probe always operates when
connected, regardless of the presence or type of
room chrono-thermostat used and can work in
combination with Immergas timer thermostats.
The correlation between system flow temperature
and external temperature is determined by the
parameters set in menu “M5” under item “P66”
according to the curves represented in the dia-
gram (Fig. 1-7). The electric connection of the
external probe must be made on clamps 38 and
39 on the boiler P.C.B. (Fig. 3-2).
