2.1.2 Summer/winter changeover
None.
It decides whether the plant is operating in the summer or winter mode based on
various options (hardware input, date, temperature). This information is required (as
an option) 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 menu > Configuration >
Configuration 1 > Su/Wi input = Yes) has the highest priority (Signal 1 = Summer).
The temperature or date can affect the changeover depending on parameterization.
Both criteria must be met when both are enabled. There will be no changeover and
the plant will operate continuously in the winter mode if no criterion is enabled.
