Scenarios for hotel rooms
For hotel rooms, the following usage scenarios are considered realistic:
HVAC
A typical HVAC scenario could look as follows:
When a room is not occupied, it operates continuously in Economy mode. The moment the
guest checks in, the hotel reservation system switches the room's operating mode from
Economy to Precomfort. As long as the room is not occupied, its temperature is maintained
at the Precomfort setpoint (20 °C for heating/26 °C for cooling). When the guest enters the
room, its temperature is raised to the Comfort level of 21 °C in the case of heating/lowered to
24 °C in the case of cooling, and then lowered/raised again when the guest leaves the room.
When checking out, the room's operating mode is reset to Economy.
The guest can adjust the Comfort setpoint to meet his/her individual needs. But when auto-
matically switching to another operating mode, the setpoints are reset to those of the room
group.
Lighting
A typical lighting scenario could look as follows:
When the hotel card is inserted, the basic lighting is switched on. Then, other lights can be
switched on manually via the pushbuttons. When leaving the room, all lights are automatical-
ly turned off after a certain period of time.
Shading
A typical blinds scenario could look as follows:
When the room is not occupied, the blinds are controlled automatically. In the winter after
sunrise, the blinds are automatically raised, allowing solar heat to enter the room. On the
other hand, when, in the summer, the sun shines on the façade, the blinds are lowered to
protect the room from solar heat. For safety reasons, the blinds are automatically lowered
after sunset.
When the room is occupied, it is up to the guest to control the blinds. Then, automatic opera-
tion is deactivated and the blinds can be controlled via the pushbuttons or the room operator
unit.
