When installing the 6000 Series LEGIOMIX® Electronic Mixing Valve, remember to turn the battery switch to the ON position in the control. This will activate charging the small 3.6V, 3-Cell rechargeable battery, it will take 72 hours after installation to reach its full charge. Once it reaches full charge, this will provide battery backup to maintain Time, Date, Region and any customized setup parameters in the event of a power outage. The battery will backup the setup parameters for up to 15 days of lost power. Although the battery will backup parameter settings, it does not have the capability to operate the control; it's for memory backup only.
