* Depending on environmental factors

Taiala Fa'apipi'i

  • Common mounting guidelines for the ERS Temp wM-Bus sensor:
  • Tuu le masini i se avanoa avanoa i luga o le puipui, faʻatasi ai ma le maualuga faʻapipiʻi o le 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.

  4. Attach the sensor to the back panel.

2.2 Auaunaga ma Tausiga
E leai ni vaega e mafai ona fa'aaogaina i totonu. Afai e mana'omia se auaunaga e ese mai i le sui o le maa, fa'amolemole fa'afeso'ota'i lau tufatufaina.
2.3 Fa'atinoga
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).
