Table 48: Settings - Blocking objects
By activating the blocking objects, one or two blocking objects are available to the user for blocking
the control value, depending on the setting of the controller type. These blocking objects are used to
prevent the actuators (heating or cooling device) from starting up unintentionally. For example, if the
heating is not to start in certain situations, e.g. when a window is open, the blocking object can be
used to block the control value. Another application of the lock object is, for example, manual locking,
e.g. via a pushbutton, in the event of a cleaning process. The blocking object blocks the control value
as soon as a 1 is sent to the associated 1-bit communication object. A 0 releases the blocking.

Heating/Cooling request
The setting "Heating/Cooling request object enabled" can be used to display objects that indicate
that heating or cooling is about to start. These objects are status objects.
The objects can be used to visualise a starting or ending heating or cooling process. For example, a
red LED could indicate a continuous heating process and a blue LED could indicate a continuous
cooling process.
Another possibility of application is the central switching on of a heating or cooling process. For
example, an additional logic gate can be used to ensure that all heaters in a building/area are
switched on as soon as a controller issues the heating request.
The 1 bit communication object outputs a 1 as long as the respective process continues. If the
process is finished, a 0 is output..
