Battery replacement

NOTE: Batteries are optional (serving as backup power) only if your thermostat is connected to 24 VAC.
Set the System switch to Off before removing the batteries. Otherwise, the
heating/cooling system could remain activated even when batteries are
removed.
Install two fresh AAA batteries when the low-battery icon flashes
on the screen. The icon appears for 60 days before the batteries
are depleted.
Replace batteries once a year, or when you will be away for more
than a month.
Most settings are stored in non-volatile (permanent) memory. Only
the clock and the day must be set if the thermostat was without AC
power or batteries.
NOTE: The low-battery icon will not appear when the batteries are
depleted if the thermostat is connected to 24 VAC.
