HVAC control
The temperature in every room is acquired and controlled. Every room sends its heat/cooling energy request to the
heating/refrigeration plant. These plants are controlled depending on the outside temperature and the heat/cooling
energy requests received from the rooms. During nonoccupancy times (rooms not booked), the room temperatures
are automatically lowered via the integrated hotel booking system. Open windows are always automatically detected
and the temperatures of such rooms are lowered/raised to save heating/cooling energy. The room temperatures are
also slightly lowered/raised during the day, if the guest is not present.
Lighting control
Presence detectors (hotel card switches) help save energy by automatically switching the lighting off when the room
is not occupied.
Blinds control
When a room is not booked (or, if desired, when the guest is absent), a weather station outside the building protects
up to 4 façades from extreme sunlight in the summer. This function helps to keep the rooms cool. The weather
station also protects the blinds from damage caused by strong winds or other natural influences. On sunny winter
days, the weather station raises the blinds to let solar radiation make a natural heat contribution.
When the guest is present, the blinds can be controlled via the pushbuttons and automatic operation is off.
Remote control
Integration of a webserver facilitates remote control and monitoring on a PC or smartphone via webbrowser.
