What is the battery used for in the electronic mixing valve control?

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.

Hello Dean, The battery is a three cell, 3.6v rechargeable that may not be available locally. The Caleffi part number for a replacement battery is F69888. The battery should hold the memory for 15 days of lost power and have a 2 year life expectancy. If the battey is not backing the conrol up you should get a "battery alarm" or have the red light lit up next to the battery picture on the front of the control indicating a battery failure. If the there is no battery alarm or failure indicator and the battery is not holding the memory you should confirm the battery installation orientation. The + side of the battery should be installed facing the bottom the the control or the battery switch.
