Possible uses for the PCD7.L79xN series
1.2.1 Standalone control with no communication
The controller regulates the room temperature without
any connection to a bus system. Control is handled
entirely by the individual room controller based on the
specified default parameter settings.
The outputs are driven by a control algorithm depending
on the measured temperature.
The default set-point setting of 21
°C can be modified
by the set-point control (according to the device).

1.2.2 Standalone control with communication to the automation station
The controller is run as a slave station with a unique
Bus address within a serial S-Net system. Control is
handled by the individual room controller with its own
control algorithm.
The control functions - time or event-driven - are
passed to the individual room controller by the
automation station via suitably configurable function
objects or network variables. This supports individual
parameterisation and operation of the room controller.
The device, and hence the control function, can also
be influenced at any time via the Saia PCD
®
master
station.
For parameterisation, there is a function object
available in the library for every room controller type. In
the case of open network connections, this is handled
via network variables or network objects.
