External Temperature Probe (Optional) - Immergas VICTRIX TERA V2 24 PLUS EU Instructions And Recommendations

1.11 EXTERNAL TEMPERATURE PROBE (OPTIONAL)

The appliance is prepared for the application of the external probe (Fig. 10), 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 appliance 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 connected, regardless of the presence or type of room chrono-thermostat used and can work in
combination 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 device control panel (or on the CA
(Fig.11).
The electric connection of the external probe must be made on terminals 38 and 39 on the terminal board on the appliance control panel
(Fig. 54).
If the probe is used, it is mandatory to set up two separate lines in compliance with current regulations regarding electrical sys-
tems.
