To scroll through the probes, use the UP and DOWN keys.
If a probe is not provided in the exchanger configuration,
dots will appear in correspondence to the probe (.....); in
the case of a probe error, there will be dashes (---.-).
Finally, each fan has its own information page that reports the status of that fan (on, off, alarm), the current
modulation value, speed in RPM, current and absorbed power.

System status appears at the centre of the Home Page. OFF indicates the standby state, in which additional features
such as coil cleaning, fan antilock and frost resistance can be activated. This why it is recommended to put the
controller in standby mode instead of switching off the exchanger during idle periods; it is also required to leave the
machine on when the ambient temperature drops below 0°C.
