In operation
General
1 bit
DPT 1.002
C, R, T
The group object is enabled if the parameter
Enable group object "In operation" 1 bit
is set to
Yes
in the
General
parameter window.
In order to regularly monitor the presence of the device on the KNX, a telegram In operation is sent cyclically
on the bus.
As long as the group object is activated, it sends a parameterizable In operation telegram.
The telegram value depends on the option selected in Parameter
Send
.

Status byte device
General
1 byte
Non DPT
C, R, T
This group object is always enabled and indicates the current device state. It indicates whether the device is
working normally or whether manual override is in effect.
This group object maps the following information:
•
Bit 0: Operating mode overridden
The controller was overridden via the group object
Operating mode override
.
This bit is always 0 in actuator mode.
–
0: No override
–
1: Override active
•
Bit 1: Building Protection
The device is in Building Protection mode due to dew point/fill level alarm or an open window
This bit is always 0 in actuator mode.
–
0: Building protection
–
1: Building protection active
•
Bit 2: Forced operation
Forced operation was activated.
–
0: Forced operation inactive
–
1: Forced operation active
•
Bit 3: Manual override
The valve was manually overridden via group object.
–
0: Manual override inactive
–
1: Manual override active
•
Bit 4: Direct operation/membrane keypad
Manual operation via the device's membrane keypad is active
This option is available only for devices with membrane keypad
–
0: Manual operation inactive
–
1: Manual operation active
•
Bit 5: Security Mode
The device is in Security Mode, e.g. due to temperature value or control value failure; a defined control
value applies (s. parameter Cyclical monitoring, Page 239).
Note
When in controller mode, the device is also in Security Mode after booting up, because the controller
has not yet received a valid temperature value.
This does not depend on whether cyclic monitoring was activated for the temperature.
The device is operating normally when the group object value is 0 (= all individual bits = 0).

DPT 1.017
C, W
This group object is always enabled.
When this group object receives a telegram with the value 0 or 1, all group objects Status are sent on the bus
if they were parametrized with
On request
.
