Valve outputs | Channel-independent functions
In this configuration, the actuator activates the most recently saved operating
mode.
The operating mode tracked after bus voltage return or preset after an ETS
programming operation is not tracked in the communication object "Summer /
winter switchover" by the actuator.
9.3.4.1 Summer / winter switchover parameters
Enabling the summer / winter mode function
General valve outputs -> Enabled functions
Summer / winter mode
The device possesses a summer / winter switchover. Depending on the season, this
allows the setting of different command value setpoints for the valve output for emer-
gency operation or forced position.
Activated: The summer / winter switchover is enabled. The communication object
"Summer / winter switchover" becomes visible. Summer and winter command values
can be configured for emergency operation and a forced position for the valve out-
put.
Deactivated: The summer / winter switchover is not available. For the valve output,
only one command value can be configured separately for emergency operation or a
forced position.
Setting the summer / winter mode function
General valve outputs -> Summer / winter mode
Object polarity
This parameter sets the telegram polarity of the "Summer / winter mode" object.
After ETS programming operation
The "Summer" or "Winter" state preset via the object "Summer / winter mode" is
stored internally in the device and is restored after a device reset (voltage return).
The parameter "After ETS programming operation" defines which operating mode is
active after ETS commissioning.
Summer operation: In this setting, the device activates summer operation after an
ETS programming operation. This overwrites the value saved internally in the
device.
Winter operation: In this setting, the device activates winter operation after an ETS
programming operation. This overwrites the value saved internally in the device.
no change (saved operating mode): In this configuration, the device activates the
most recently saved operating mode.
