2.7 Summer/winter changeover from keyboard
The unit must be switched OFF and the summer/winter changeover from keyboard must be enabled.
Select “Summer/Winter” menu "Enter"
"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
changeover is done with the unit in ON status, so the control will first stop all active devices (compressors, electrical
heaters, etc.), except main fans, and it will restart them automatically when the changeover is done, following the
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.
