Device selection
2. Device selection
2.1 Which devices/applications are available in practice in conjunction
with KNX?
– Both cooling and heating functions are implemented.
– Convectors, fl oor heating, cooling ceilings, and less frequently, electrical heating
systems are used.
– Fan Coil Units can also be used; for control purposes, either special actuators
(FCA/S 1.1M) or switch actuators with a matched application are used.
– Generally, a KNX thermostat (alpha nea ® , Busch-triton ® , Busch-priOn ® or solo ® as well
as the Room Thermostat Fan Coil with Display RDF/A 1.1) are used. The Controlpanel
as well as the Busch-ComfortTouch ® may also be used as thermostats. Busch-priOn ®
and Busch-ComfortTouch ® in combination offer a further solution, see chapter 2.2.2.5.
– The actuators that are used are switch actuators and electronic actuators that each
feature electrothermal valve drives or direct electromotor valve drives with KNX
connection.
– A special solution is the use of the Universal Interface US/U x.2 with electronic relays
and electrothermal valve drives.
– Special solutions such as the use of KNX-enabled boilers, implementation of central
control functions with an analogue input or output and separate control modules etc.,
are not dealt with in this chapter.
