Set the parameter to "Activate command value according to emergency opera-
tion".
For the valve output, the actuator polls the emergency operation command
value, as configured in the ETS. Here, the active operating mode (summer /
winter) is taken into account, providing that a summer / winter change-over is
configured. Ensure that, in this setting, emergency operation is not executed
(as would be the case if there was a faulty command value found in the course
of command value monitoring)! The actuator only polls the command value
preset for emergency operation.
The behaviour after an ETS programming operation is only executed if there
have been changes in the configuration of the device. If just an application
download is executed with a project design already located in the actuator,
then the actuator will execute the configured "Behaviour after bus voltage re-
turn".
A valve state set after an ETS programming operation is added to the com-
mand value status objects. The feedback objects also only first transmit after
an ETS programming operation when the initialisation has finished and, if ne-
cessary, the "delay time after bus voltage return" has elapsed.
An active manual operation mode will be terminated by an ETS programming
operation.
9.4.6 "Valve output - General" parameters
Valve output x - General
Name of valve output
The text entered in this parameter is applied to the name of the communication ob-
jects and is used to label the valve output in the ETS parameter window (e.g. "Un-
derfloor heating living room").
The text is not programmed in the device.
Command value input
Data format
The actuator can optionally be controlled via a 1-bit object or a 1-byte object.
Switching (1-bit): In the case of a 1-bit command value, the telegram received intern-
ally in the device is forwarded directly to the output of the actuator, taking the con-
figured valve direction of action into account.
Constant (1-byte): In the case of a 1-byte command value, the following parameter
"Activation with" determines the type of processing of the command value.
