The following describes the individual steps required. The description includes
examples for clarification. Please refer to the user's guide to the HOTEL SOLUTION
User Interface for information on how to make additional settings.
1
Assign all rooms to suitable energy groups. If the existing energy groups do not
meet the requirements, set up others. Rooms should be assigned to groups
bearing in mind which rooms will be dealt with together. In the "3-house hotel"
referred to above, for example, the obvious approach is to define three energy
groups. If a more detailed differentiation is required, the individual floors in each
house could each represent one energy group.

2
Later, a specific room state will be allocated to the rooms in a given energy group.
For this purpose, only an existing room state can be used (e.g.: "Standby C").
3
Since the room state and the temperature profile are combined to represent a
temperature setpoint, the active temperature profile for the system must be
defined first.
4
In the user interface, enter for each room state the temperature setpoints
associated with the required temperature profile.
The following is an illustration:
A hotel, consisting of three buildings, is closed throughout February. However,
House 1 must be kept ready for special guests. The setpoints in House 2 and
House 3 should be set to 13 °C.
• Energy groups are set up for House1, House2 and House3. The rooms in each
house are assigned to the associated energy group. Normally, this task only
needs to be carried out once.
• The available states are: Comfort, Standby A, Standby B and Standby C
• The available temperature profiles are: Autumn, Spring, Summer, Winter
