1.17 EXTERNAL TEMPERATURE PROBE (OPTIONAL)
The Outdoor Unit has a standard external probe that can be used as an external probe of the heat pump.
This can be used as an external probe of the heat pump.
If the Outdoor Unit is positioned in an area that is not suitable for temperature reading, it is advisable to use an additional external probe
(Fig. 15) which is available as an optional kit.
Refer to the relative instruction sheet for positioning of the external probe.
For the proper operation of the optional probe, it must be connected where envisaged (Fig.14) and then enabled (Par. 1.18).
Once the probe is enabled, switch the appliance off and back on.
The presence of the external probe allows the system flow temperature to be set automatically based on the outdoor temperature in order
to adapt the heating or cooling provided to the system.
The system flow temperature is determined by the setting on the "Heat regulation" menu and by the "User" menu for the offset values
based on the curves shown in the diagram (Parag. 1.18).
If the system is divided into two or three zones, the flow temperature is calculated based on the zone with the higher tempera-
ture in central heating mode and with the lower temperature in cooling mode.
The electric connection of the external probe must be made on terminals 38 and 39 on the terminal board on the Indoor Unit control
panel (Fig. 14).
In case of failure, after having powered off and back on, the outdoor temperature is automatically detected by the external probe on the
Outdoor Unit.
