Another object for receiving the time of day for display on the room
thermostat. See parameter P07 (3 or 4)
4 Fault information Alarm

Common alarm output. If an alarm occurs, the alarm number is
transmitted

CWU
A supervisor alarm system can disable the broadcasting of alarms
by the devices. This has no impact on the local display of alarms.
After a timeout of 48 hours, the sending of faults will automatically
be enabled again.

CWTU
Controls the room operating mode selection of the thermostat via
bus.
The command can also be submitted as four 1-bit communication
objects (8...11). The last interaction wins – either from local
operating mode button or via bus.
Note: The thermostat will transform Precomfort either into
Economy or Comfort (selectable via P88).

CWU
This information is provided by a central time switch or a
supervisor and defines the actual HVAC operating mode.
The command can also be submitted via three 1-bit
communication objects (13...15).
Protection has the highest priority and cannot be overridden.
Note: The thermostat will transform Precomfort either into
Economy or Comfort (selectable P88).

CRT
Effective room operating mode used by the thermostat
(considering time switch, user selection, window contact, etc.) This
state information is available via one 8-bit enumeration or three 1-
bit communication objects (17...19). Note: The thermostat does not
support Precomfort.

1.019
1 bit
CWU
The thermostat is set to Economy mode if value “1” (open) is
received. It switches back to the previous mode when the value is
“0” (closed).
"Window state" is sent e.g by a KNX switch or a KNX presence
detector. It has the same effect as the local operating mode
switchover contact X1, X2 (parameter P38, P40).
Only one input source must be used, either local input X1/X2 or
KNX bus.
21 Room

The value of the room temperature measured via built-in or
external sensor is available via this communication object.

ture: Comfort
basic setpoint
Temp .
value
9.001
2 Bytes
CWU
If function "Temporary setpoint" is enabled via parameter P69, then
after an operating mode change, the setpoint adjustments made by
the user and via communication object 23 will be dismissed and
the thermostat will be reset to the Comfort basic setpoint.
Note: Setpoints that have been changed via the local HMI may be
overwritten during a system startup from a central master
controller, e.g.RMB795.
The Comfort basic setpoint is stored in EEPROM (see section
3.3.2).
The service life of the EEPROM depends on the number
of write cycles. Never write this communication object cyclically!
23 Room
temperature:
Comfort setpoint
Temp .
value
9.001
2 Bytes
CWTU
Communication object used to shift the setpoint used by the
thermostat (see section 3.3.2). Same priority as local setpoint shift
on the ther
mostat. The last intervention wins.
Note: The Comfort basic setpoint (object 22) will not be changed.
24 Current setpoint Temp .
value
9.001
2 Bytes
CRT
Current setpoint, including shift, compensation, etc., used by the
thermostat for temperature control
