No
Relay output
This parameter establishes a direct connection between the binary input and the relay output, dis-
pensing with the need for group address assignment.
The Status object on the input is updated along with that on the output.
NOTICE
This function allows you to switch the additional relay directly. If the device is being used in con-
troller mode, switching occurs regardless of the function of the controller. If the relay is being
used to switch an electric heater, then depending on the application, this can result in the heater
being switched on when the fan coil unit is not running, which in turn can lead to the unit over-
heating.

On object value

Note
Cyclic sending
Cyclic sending enables the
Switch
group object to send automatically at a fixed interval. If cyclic
sending applies to a specific object value only (ON or OFF), this condition refers to the value of
the group object. It is therefore possible in principle to start cyclic sending by sending a value to
the
Switch
group object. As this behavior is unwanted, the Write and Update flags of the group
object are deleted in the preliminary setting so that they cannot be changed via the bus. If this
functionality is required irrespectively, set these flags accordingly. When the group object
Switch
changes and after bus voltage recovery (after the sending delay time has elapsed), the group ob-
ject value is sent immediately on the bus, and the sending cycle time restarts.
