Operation with external probe
It is possible to use the thermoregulation functions associated to an external probe.
The system is standard set up to use the outdoor unit external probe or an optional external probe.
With the external probe connected and the thermoregulation function active, the system flow setpoint for room central heating / C.H. or
cooling is managed by the system according to the outdoor temperature measured (Par. 1.12).
You can correct the flow setpoint by choosing the offset value in the specific user menu.
It is possible to enable thermal adjustment for each individual zone. The symbol is present in case of thermoregulation of at least one zone.
