INSTALLATION INSTRUCTIONS
Connecting the batteries and starting the controller
Remove the terminal panel under the LCD of the unit by pushing up on the tab.
Insert two new AA Alkaline (LR6 in Europe) batteries into the battery clips in the
pocket directly above the terminal strip. The AA batteries enable the EZ Pro
to be programmed without AC power and maintain the programs and real time
clock in the event of a power outage. If the batteries are not installed, and the
Lithium battery has not been activated, the controller will lose real time and
programs in the event of a power outage. The batteries should be replaced every
five years, or when low battery symbol appears.
CAUTION: Use AA alkaline batteries only. NiCad batteries may leak or
explode causing personal injury or property damage.

the unit for the main backup battery. To activate the Lithium Battery backup,
remove the tab marked "PULL" located under the AA battery compartment.
Attach the battery/wiring cover, being sure not to damage wires. If wires are
stiff, you may find it helpful to pre-bend them. Turn on the power source.
