5.1.2 Summer Winter changeover
None.
It decides whether the plant is in summer or winter operation based on various op-
tions (hardware input, date, temperature). This information is required (as an op-
tion) to shut down humidification in summer, to changeover the Combi Coils and to
changeover temperature control (Tmp control mode = RmSplyC Su or RtSplyC Su).
A hardware input enabled for the changeover (Main Index > Configuration > Con-
figuration 1 > Su/Wi input = Yes) has the highest priority (Signal 1 = Summer).
The temperature or date can affect the changeover depending on parameteriza-
tion. Both criteria must be met when both are enabled. There is no changeover and
the plant in continuously in winter operation when no criterion is enabled.

Function
Displays present status for summer and winter op-
eration.
Go to page to parameterize summer/winter
changeover.
Displays whether one of the outputs is not in auto
mode (intervention via HMI), a sensor is out of ser-
vice or the manual operation mode is not on auto.
Go to page with all digital inputs, e.g. to set the
alarm class for enabled manual alarm.
– Auto mode: No element in manual mode or out
of service.
– Manual mode: At least one element is in manual
