The allocation of rooms is governed by the following:
All energy groups are assigned a priority number, which determines the order of the
energy groups from which to allocate the rooms. Rooms in another energy group are
only allocated when all the rooms of one energy group have been allocated. This
ensures demand-based use of the separate heating circuits. The diagram below should
clarify this.

Fig. 2-1: Schematic layout of hotel
There are two possible approaches to the allocation of rooms to energy groups. (This
depends on the layout of the heating circuits.)
All areas for general access, such as the foyer, lifts, etc. need to be supplied by
separate heating circuits.
The individual energy groups are based on the layout of the heating system, and are
therefore set up when the hotel database is generated. Energy groups and assignment
to energy groups can be managed retrospectively using the commissioning functions of
the HOTEL SOLUTION user interface.
To avoid repeatedly subjecting the same rooms to excessive wear and tear, the hotel
staff should vary the priority numbers originally assigned to specific energy groups by
the commissioning engineer. For this purpose, too, there is an appropriate option in the
Energy Management menu of the user interface.
To enable the hotel staff to assign the rooms within a given energy group in the
required order, a priority number is also assigned to each room. This determines the
order in which the rooms are allocated within a given energy group. If a room is to be
withdrawn from the group, for redecorating, for example, it is assigned a priority of "0",
and will then not be allocated.
