Gebrauchsanweisung Steuerung ESP-TM

The ESP-TM controller is factory-supplied with a 3-Volt
lithium coin cell backup battery, which is wrapped in a
protective insulator strip in the battery drawer. This battery
is designed to maintain program information for several
days without power.
If electrical power to the ESP-TM remains uninterrupted,
the lithium coin cell will last well over one year. However,
long or frequent power interruptions will use up the battery
much faster.
To activate this battery, remove the lower face panel on the
controller and remove the plastic insulator strip from the battery.
Make sure battery drawer is completely closed, then reinstall
the lower face panel. See page 25 for complete instructions.
