Failure to observe the recommendations included in this manual may be dangerous or cause a violation of the law. The manufacturer, Elektronik System i Umeå AB, will not be held responsible for any loss or damage resulting from not following the instructions of this operating manual.
- Kaua te taputapu e wetewete, e whakarereke ranei i tetahi huarahi.
- Ko te taputapu mo te whakamahi i roto anake. Kaua e tukuna ki te makuku.
- The device is not intended to be used as a reference sensor, and Elektronik System iUmeå AB will not be held liable for any damage which may result from inaccurate readings.
- Me tango te pākahiko mai i te taputapu mena kaore e whakamahia mo te wa roa.
- Otherwise, the battery might leak and damage the device. Never leave a discharged battery in the battery compartment.
- Kaua rawa te taputapu e pa ki nga wiri me nga paanga.
- Hei horoi i te taputapu, horoia ki te kakahu makuku ngawari. Whakamahia tetahi atu kakahu maeneene, maroke hei horoi kia maroke. Kaua e whakamahi i te hopi horoi, waipiro ranei hei horoi i te taputapu.
- WHAKATAHI – Morearea o te pahū ki te whakakapihia te pākahiko e te momo hē
Panui tuku kia rite ki te Parapara mai i nga Taputapu Hiko me te Hiko (WEEE) Arataki 2012/19/EU
Ko te taputapu, tae atu ki nga waahanga katoa, kaua e tukuna ki te para o te whare, ki nga para ahumahi ranei. Me tuku e koe te taputapu i te mutunga o tona oranga i runga i nga whakaritenga o Directive 2012/19/EU hei tiaki i te taiao me te whakaiti i te para ma te hangarua. Mo etahi atu korero me pehea te mahi tuku, whakapaa atu ki nga kaiwhakarato ratonga tuku whaimana. Kei roto i nga pukoro he pākahiko lithium, me wehe motuhake.
Whakaahuatanga
The ERS Temp wM-Bus sensor is an indoor climate sensor that communicates on wM-Bus and measures Temperature with long expected battery time.
1.1 ERS Temp wM-Bus Attributes
The ERS Temp wM-Bus attributes are Temperature, wM-Bus, and no NFC.
1.2 Tapanga
The Barcode is of Aztec type and contains DevEUI and sensor type. This label is located at the back of our device.
1.3 Ahu
Measurements are given in millimeters

1.4 Main Features of the ERS Temp wM-Bus
- Wireless M-Bus mode
- Wireless M-Bus standard EN13757:2018
- Ka ine i te pāmahana ambient
- 15 years of battery life*
- Tāutatanga ngawari
- IP30
- OMS 4.0 Compatible
* Depending on environmental factors
Nga Aratohu Whakapuru
- Common mounting guidelines for the ERS Temp wM-Bus sensor:
- Whakanohoia te pūoko ki tetahi waahi tuwhera i runga i te pakitara, me te teitei whakaurunga o te 1.6 mita.
- For best RF and measurement performance, make sure you mount the sensor with the ventilation openings vertically. See installation in chapter 2.1
- Make sure that the sensor is not placed in direct sunlight, close to heating vents, near windows, air ventilation where it may measure values that are not representative of the rest of the room.
- Do not mount the sensor in a steel cabinet. Doing so will dramatically decrease the signal coverage.
2.1 Tāuta
- Tangohia te papa o muri o te pūoko ki te huriwiri iti.

- Install the Battery. The ERS Temp wM-Bus requires one AA battery. The battery type is 3.6V Lithium Battery (ER14505). Use battery slot A.

- Mount the back panel to the wall with at least 2 appropriate screws, using any of the four mounting holes. Alternatively attach the sensor using double sided adhesive tape.

- Attach the sensor to the back panel.
2.2 Ratonga me te Tiaki
Kaore he waahanga e taea ana ki roto. Mena ka hiahiatia he ratonga i tua atu i te whakakapi i te pākahiko, tena waea atu ki to tohatoha.
2.3 Mahi
Upon Installation of the batteries, the sensor will begin to transmit wireless M-Bus telegrams. The telegrams contain sensor data as well as various information about the product status.
2.4 Wireless M-bus mode
The ERS Temp wM-Bus has one mode which is C1A. And is OMS 4.0 compatible. The wM-Bus Telegram is encrypted (AES).
