2.4 Changing the room operating modes
The hotelier should have the facility to modify the operating mode of any room in
Standby mode at any time vie the user interface. This ensures that the rooms can be
brought to the appropriate temperature if an unexpectedly large number of guests want
to check in on the same day.
In normal circumstances, however, the system should be able to use the empirical data
supplied by the hotelier to calculate the number of rooms in the various standby modes
and to set them to the required mode independently.
After HOTEL SOLUTION receives the data from the FOS, all rooms need to be set to
the required standby mode.
When setting Standby A, the number of guest rooms concerned must take account of
the guests checking out that day. The calculation is illustrated below, using the same
abbreviations as before (see Section 2.3):
Standby A = R – O + WI + S
When the number of Standby A rooms has been calculated, the associated datagrams
are transmitted to the room controllers, firstly on the basis of the "firm bookings" room
list, and then on the basis of the "priorities" list, so that the new room setpoints can be
programmed.
Note that firm bookings no longer appear in the priorities list.
The number of Standby B rooms is specified by the user. Datagrams are generated on
the basis of the priorities list and transmitted to the room controllers.
The remaining rooms are set to Standby C mode.
