Keypad
Lift the front cover to see the keypad. From the
keypad, you can operate and program the
thermostat. To operate the thermostat, press
and release the keys.
NOTE: The thermostat registers all program-
ming inputs immediately and main-
tains them until manually changed.
Low batteries or power outages do
not delete thermostat programming.
Battery Compartment
The battery compartment under the left side of
the front panel contains two AA batteries that
keep the clock running during a power interrup-
tion.
Replacing Thermostat Batteries
IMPORTANT
Install batteries to maintain the time in
the event of a power loss. Although
the thermostat has a low battery
indicator, replace the batteries once
every two years to prevent the
thermostat from losing the time during
a momentary power loss.
NOTE: If the time is ever incorrect, you can
not change it. Your energy utility
periodically updates the clock to the
correct time.
