"Enter" to change unit working mode.

If the changeover from digital input is enabled, mask R0 is not visualized.

If the automatic changeover is enabled, the changeover from winter mode to summer mode is done automatically

when the indoor air temperature rises above the summer setpoint, while the changeover from summer mode to winter

mode is done automatically when the indoor air temperature falls below the winter setpoint. In any case, the automatic

thermal load request.

In order to have the automatic summer/winter changeover working properly, winter setpoint must be

lower than summer setpoint; if not, the control will activate an alarm that will stop the unit; this alarm

will be automatically reset when the summer and winter setpoint are properly set.
