Use
The HRC3.2 room controller integrates temperature control, energy management,
access control and the management of a hotel room, at room level.
For operation, use is made of room operator units, access card readers and access
card holders with a switch to turn on the lights, for example, and a connection to the
bus.
Functions
The functions are determined by the downloadable application software.
The room controllers are delivered with the standard application (the basic features are
described in this data sheet).
In special cases, the standard application may be overwritten with a definitive
customized application software. A commissioning and service tool is available for this
purpose.
