Setup instructions
Before installing STM 550 into its intended location, a sufficient initial charge should be pro-
vided to STM 550 and its correct operation should be verified.
To do so, follow these steps:
1.
Place STM 550 under bright light (daylight or bright light source) for 5 minutes to
provide an initial charge
2.
Press the LRN button once so that STM 550 will start operation
3.
Check that STM 550 transmits radio telegrams at the configured update interval (by
default once every 60 seconds). The LED will blink every time a telegram is trans-
mitted (unless this has been disabled via NFC).
4.
Use a suitable receiver to capture the STM 550 data telegrams and verify that all re-
quired parameters are reported. Consider disabling the measurement and reporting
of non-required parameters to conserve energy.
5.
Check the light level reported by STM 550 at the intended installation location to
verify that sufficient light is available for the energy harvesting functionality. Maxim-
ize the amount of light available for energy harvesting as much as possible.
6.
Make sure that the installation location is chosen according to the guidelines in the
subsequent chapters to maximize the measurement accuracy.
After those steps, STM 550 is ready for installation into its intended location.
