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 together with RM… controllers, RXB/RXL room controllers, RDG/RDF/RDU room thermostats, and QAW740 room unit.
