DESCRIPTION

22/30448003 DC


This standard 22/30448003 DC BS EN 17690-1. Components for BAC Control Loop. Sensors is classified in these ICS categories:
  • 17.200.20 Temperature-measuring instruments
  • 91.140.10 Central heating systems
This document specifies requirements and test methods for room temperature sensors used to control the room temperature. This document covers wall mounted and flush mounted room temperature sensors. The following aspects are not covered by this document: - Pendulum temperature sensors - Ceiling mounted temperature sensor - Extract air temperature sensors NOTE The measured value available at the output of the sensor is influenced by the place where the sensor device is located and factors such as air velocity, wall temperature, self/waste heating of the device and the air temperature. The perceived temperature, which is important for the well-being of a person, depends among other factors on air temperature, temperature of the surrounding walls and air flow rate as indicated in EN ISO 7730. The temperature sensor element can be combined with other sensors in one device. This document only deals with the room temperature sensing of this devices. Other sensors are not covered except of their influence on the room temperature sensing (e.g. self-heating). This document specifies sensor characteristics contributing to the determination of the control accuracy of individual zone controller according to EN 15500 1.
