2.3 FOS and Siemens HOTEL SOLUTION

For hotels already installed with front-office systems such as Hogatex, it will be noted

that these products have their own reservation algorithms. However, as they do not

have an energy management component, the data needs to be transferred.

The flow of data always applies to all room types (single rooms, double rooms or

suites etc.)

In the case of the Hogatex FOS, the flow of data traffic is as follows:

• Number of reservations for that day (with room numbers)

transmitted once at xx:00 hours.

• Number of departures on that day (with room numbers)

transmitted once at xx:00 hours.

• Number of firm bookings for that day (with room numbers)

transmitted once at xx:00 hours.

• All room numbers with room status and priority,

transmitted once at xx:00 hours.

The HOTEL SOLUTION software uses the data from the Hogatex system to set all the

rooms reserved for that day to "Standby A" mode at a specific time (refer to the user's

guide to the User Interface, Section 13, "Room states and temperature profiles"). As

soon as the guest actually checks in, the room is heated to the comfort temperature.

The following shows how many rooms need to be set to which standby mode. "Offline"

in this context refers to all rooms for which the "RCU Offline" attribute is set to 1 in the

Rooms table.

Standby A = R + WI + S

Standby B = U

Standby C = SM – Standby A – Standby B – Comfort – Offline

R - Number of reservations for that day

O = Number of guests checking out on that day

WI = Number of "walk-ins" (immediate bookings without prior reservation)

S = Number of backup rooms (safety margin)

U = User-defined number of rooms for the current mode

SM = Sum total of all rooms
