Valve outputs | Channel-independent functions
The "Summer" or "Winter" state preset via the object is stored internally in the device
and is restored after a device reset. In the ETS, it is possible to configure whether,
after an ETS programming operation, the saved value is restored or, alternatively, if a
defined operation (summer or winter) is activated.
It is also possible to switch the operating mode during active emergency operation (if
called by command value monitoring) or during an active forced position (if activated
via the object). In this case, the value belonging to the operating mode is activated
immediately after the switchover. If the value for emergency operation or the forced
position is polled on a bus/mains voltage return or after an ETS programming opera-
tion, the command values do not change when the operating mode is switched over.
Enabling summer / winter switchover
The summer / winter switchover must first be enabled on the "General valve outputs"
parameter page, so that it is possible to switch between summer and winter mode
during actuator operation. The remaining parameters are set on the parameter page
"Summer / winter mode switchover". Additionally, the parameter pages of the indi-
vidual valve outputs are relevant.
￭
Configure the parameter "Object polarity" to the required telegram polarity.
The summer / winter switchover is enabled. The communication object "Sum-
mer / winter switchover" becomes visible in the ETS. On the parameter pages
of the individual valve outputs, summer and winter command values can be
configured for emergency operation and for a forced position.
￭
Deactivate the checkbox "Summer / winter mode" on the parameter page
"Valve outputs -> General valve outputs".
The summer / winter switchover is not available. For the valve outputs, only
one command value can be configured separately for emergency operation or
a forced position.
Defining the behaviour after of the summer / winter switchover during an ETS
programming operation
The "Summer" or "Winter" state preset via the object "Summer / winter switchover" is
stored internally in the device and is restored after bus voltage return. The parameter
"After ETS programming" on the parameter page "Summer / winter mode switchover"
also defines which operating mode is active after ETS commissioning.
￭
Set the parameter to "Summer mode".
In this setting, the actuator activates summer operation after an ETS program-
ming operation. This overwrites the value saved internally in the device.
￭
Set the parameter to "winter mode".
In this setting, the actuator activates winter mode after an ETS programming
operation. This overwrites the value saved internally in the device.
￭
Set the parameter to "No change (saved operating mode)".
