10. Battery and replacement procedures
The thermal energy meter constantly monitors the status of the battery (
maximum life: 10 years*
)
and signals the imminent discharge by showing the icon on display . Reporting takes place one year
before full discharge.For more details see the separated WMBUS specification document.
For replacement, contact the manufacturer.
*The battery life strongly depends on the working time window, set during the configuration process, and on the
environmental conditions. Estimation of the battery life is given by the configuration software.
Do not recharge or replace the battery;
Do not open, puncture or damage the batteries;
Do not short-circuit the battery;
Do not expose the battery to temperatures above
85° C;
Do not use naked flames near the device;
Do not put in contact with water;
Do not insert into ovens, crush or cut: these actions
could cause an explosion or leakage of
flammable gases or liquids;
Always dispose of batteries in compliance with
current regulations;
The thermal energy meter uses non-rechargeable batteries that, if misused, can be potentially
dangerous. To reduce the risks, you should take the following precautions:
