4.4.7 Lock objects
The following table shows all available settings:
ETS-Text
Dynamic range
[Default value]
Comment
Lock object: Control value Heating
▪ not active
▪ active
Activates the lock object for the
heating process.
Lock object: Control value Cooling
▪ not active
▪ active
Activates the lock object for the
cooling process.
Table 52: Settings – Lock objects for control value
By activating the lock objects, the user has one or two lock objects available for locking the control
value, depending on the setting of the controller type. These lock objects serve to prevent the
actuators (heating device or cooling device) from starting up undesirably. For example, if the
heating is not to start in certain situations, e.g. when the window is open, the lock object can be
used to lock the control value. Another application would be manual locking, for example in the
event of a cleaning process. The lock object locks the control value as soon as a “1” is sent to the
associated communication object. The lock is cancelled with a “0”.
The following table shows the available communication objects:

Comment
Object for Heating request

Activates an object to indicate whether

Activates an object to indicate whether
a cooling request is present or not.
Table 54: Settings –Objects for Heating/Cooling request
The setting "Object for request Heating/Cooling" allows objects to be displayed that indicate an
active heating or cooling process. The objects can be used for a visualisation. For example, a red
LED could indicate an ongoing heating process and a blue LED could indicate an ongoing cooling
process. Another possible application is the central switching on of a heating or cooling process.
For example, it can be realised via an additional logic that all heaters of a building/area are
switched on as soon as a controller issues the request for heating. The object outputs a “1” as long
as the respective process continues. When the process is finished, a “0” is output.
