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 of the lock object is, for example, manual locking, e.g. via a
push-button, in the event of a cleaning process. The lock object locks the control value as soon as a
"1" is sent to the associated 1-bit communication object.
The following communication objects are available for this:
