1.9 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 for positioning of 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 temperature.
The external probe always operates when con-
nected, regardless of the presence or type of room
chrono-thermostat used and can work in combi-
nation with Immergas chrono-thermostats. The
correlation between system flow temperature
and external temperature is determined by the
position of the central heating selector switch on
the boiler control panel (or on the CAR
V2
control
panel if connected to the boiler) according to
the curves shown in the diagram (Fig. 1-7). The
electric connection of the external probe must be
made on clamps 38 and 39 on the terminal board
in the boiler control panel (Fig. 3-2).
