USER MANUAL ETHSU – EASYFIT TEMPERATURE AND HUMIDITY SENSOR © 2017 EnOcean | www.enocean.com F-710-017, V1.0 ETHSU User Manual | v1.0 | December 2017 | Page 5/14 2 GENERAL DESCRIPTION 2.1 Basic functionality EnOcean EasyFit ETHSU is a wireless and maintenance free temperature and humidity sensor. It requires no external components and provides on-board a calibrat-ed temperature and humidity sensor. Power supply is provided by a small pre-installed solar cell or an external 3 V backup battery. An energy storage element is installed in order to bridge periods with no supply from the energy harvest-er. The module provides an internal cyclic wake up every 100s. After wake up, the internal microcontroller reads the status of the temperature and humidity sensor. A radio telegram will be transmitted in case of a signifi-cant change of measured temperature or measure hu-midity. In case of no relevant input change, a redundant retransmission signal (heartbeat) is sent randomly within 8 to 15 minutes to announce the current values. In addition to the cyclic wake-up, a wake up can be triggered externally using the input for the occupancy button or the internal LRN button. Key product features  Fully autonomous operation under sufficient lighting with pre-installed solar cell  Factory calibrated on-board temperature and humidity sensor  Integrated energy storage and charging circuit  Integrated LRN button and TX indicator LED

Therefore products have to be taken into operation after 36 months. The module shall not be placed on conductive materials, to prevent discharge of the internal energy storages. Even materials such as conductive foam (ESD pro-tection) may have negative impact.

USER MANUAL ETHSU – EASYFIT TEMPERATURE AND HUMIDITY SENSOR © 2017 EnOcean | www.enocean.com F-710-017, V1.0 ETHSU User Manual | v1.0 | December 2017 | Page 9/14 3.2 Simplified device block diagram 3.3 Radio telegram format ETHSU transmits telegram data according to EEP (EnOcean Equipment Profile) A5-04-03 which encodes a temperature range of Temperature -20 ... 60°C with 10 Bit and a Humidity range of 0 ... 100 % r.h. with 8 Bit. 3.3.1 Teach-in telegram If the user presses the LRN button then the module transmits a teach-in telegram. With this special teach-in telegram it is possible to identify the manufacturer of a device and the function and type of a device via the EEP or GP used. By default EnOcean Manufacturer ID is set. Customers should configure the module to use their own Manufacturer ID. 3.3.2 Transmit timing The setup of the transmission timing allows avoiding possible collisions with data packages of other EnOcean transmitters as well as disturbances from the environment. With each default transmission cycle, 3 identical sub-telegrams are transmitted within 40ms. Transmission of a sub-telegram lasts approximately 1.2ms. The delay between the three transmission bursts is affected at random.

Since the expected transmission range strongly depends on this system conditions, range tests should categorically be performed before notification of a particular range that will be attainable by a certain application. The following figures for expected transmission range may be used as a rough guide only:  Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls  Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls  Ferroconcrete walls / ceilings: Typically 10 m range, through max. 1 ceiling  Fire-safety walls, elevator shafts, staircases and supply areas should be considered as screening. The angle at which the transmitted signal hits the wall is very important. The effective wall thickness – and with it the signal attenuation – varies according to this angle. Signals should be transmitted as directly as possible through the wall. Wall niches should be avoid-ed. Other factors restricting transmission range:  Switch mounted on metal surfaces (up to 30% loss of transmission range)  Hollow lightweight walls filled with insulating wool on metal foil  False ceilings with panels of metal or carbon fiber  Lead glass or glass with metal coating, steel furniture The distance between EnOcean receivers and other transmitting devices such as comput-ers, audio and video equipment that also emit high-frequency signals should be at least 0.5 m. A summarized application note to determine the transmission range within buildings is available as download from www.enocean.com.

Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélec-trique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions suivantes: 1. L’appareil ne doit pas produire de brouillage, et 2. L’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement. Ces limites sont conçues pour fournir une protection raisonnable contre les interférences nuisibles dans une installation résidentielle. Cet équipement génère, utilise et peut émettre une énergie de radiofréquence et, s'il n'est pas installé et utilisé conformément a ux in-structions, il peut causer des interférences nuisibles aux communications radio. Cependant, il n'existe aucune garantie que des interférences no se produiront pas dans une installation particulière. Si cet équipement provoque des interférences nuisibles à la réception radio ou télévision, ce qui peut être déterminé en mettant l'équipement hors et sous tension, l'utilisateur est en-couragé à essayer de corriger l'interférence par une ou plusieurs des mesures suivantes:  Réorienter ou déplacer l'antenne de réception.  Augmentez la distance entre l'équipement et le récepteur.  Connecter l'équipement à une sortie sur un circuit différent de celui sur lequel le ré-cepteur est branché.  Consulter le revendeur ou un technicien radio / télévision expérimenté pour de l'aide
