About the card holder function
The information of card insertion (removal) in (from) a card holder allows you to directly control the
temperature by means of the room thermostat, while sending the object value on the bus allows you to
control other room functions with KNX (lighting, electrical loads, feedback status for the hotel reception, etc.)
depending on the configuration done with ETS. The value of the setpoint temperature and the switching have
to be defined with the hotel responsible in accordance with the target of energy saving and level of service to
be offered to the guests.
Conventional (not KNX) card holder
With a conventional card holder the status (card present or absent) of a signal contact is detected through an
input of the device configured as
[DI] card holder contact sensor
. This way you can detect only the insertion
and extraction of the card, but it cannot be detected e.g. the access of users with different profiles (guests,
service staff, maintenance workforce).
KNX card holder
With a KNX card holder you can differentiate the switching to be carried out; this is not resolved by the
parameters of the room temperature controller, but through the definition of scenes that are received by the
device. Depending on the available device, advanced functions are possible (e.g. different user profiles).
