7.1.3 Geographical zone (apartment)
The term "Geographical zone (apartment)" is specified by KNX and implies a
building divided into geographical (physical) zones. However, in practice it is
related to the operating strategy, which is defined as follows:
• One "Geographical zone (apartment)" consists of a number of buildings or parts
of buildings which are grouped together from an operational point of view and
which obey the following criteria:
− Same room operating mode
− Same room temperature (setpoint, actual value).
Based on this definition, the "geographical zone (apartment)" might better be
referred to as an "operating zone".
The "geographical zone (apartment)" is used in conjunction with the RM…
controllers, the RXB/RXL room controllers and the QAW740 room unit.
