The batteries are easily accessible from the battery door located on
the bottom front of the thermostat (fig. 1). To open the battery slot,
pull out on the battery door (fig. 1) and swing down (fig. 2).
Remove the old
batteries and replace
with the new AA
alkaline batteries
(fig. 3).
Push up on the battery door
and snap closed (fig. 4).
The batteries must be replaced immediately when the thermostat
displays the low battery icon (fig. 1). If the thermostat is
connected to 24v power, the batteries should still be installed.
Installing the batteries when system powered (24VAC) will keep
the clock running in the event of line power interruption.
