Control for heating, ventilating and air-conditionering applications - Electronic individual zone control equipment
The purpose of this standard is to specify the applications, functionality set and application performance for electronic individual zone control equipment. The applications are for cooling and hot water or electrical heating as described in Annex B.
This standard applies specifically to individual zone control equipment for maintaining temperature, humidity and air flow as a function of occupancy and demand operated with auxiliary electrical energy.
Information required for the operation of the equipment may be processed using either analogue or digital techniques or a combination of both. Safety requirements remain unaffected by this standard.
This standard refers to the input and output requirements of the controller and not of the input and output devices as e. g. sensors and actuators.
This standard covers fixed-function, configurable and programmable controllers.
The control equipment may or may not be connected to a data-network however communications aspects are not covered by this standard.
These devices could be applied for any kind of building, intermittent or non-intermittent occupation, residential or non residential (see Annex B).
