Battery Replacement

Coin cell
battery tray
Insert the coin cell battery in the coin cell battery
tray and push it inside the battery cover assembly
The UtilityPRO is shipped from the factory with the coin cell installed. To keep the battery
from discharging during shipment and storage, the UtilityPRO is shipped from the factory
with a plastic tab inserted in the battery holder. This tab must be removed before the
thermostat is mounted on the wall. Simply pull the plastic tab out of the thermostat. To
replace the battery, remove the battery tray using a screw driver. Place a new coin cell (type
CR2032 or equivalent) observing the correct polarity and push the battery tray into the
battery cover assembly.
The UtilityPRO has a coin cell
battery that retains the time and date
during a power failure. Under normal
circumstances the coin cell should
last five years. Should the time and
date need to be reset after a power
failure, this is an indication that the
coin cell needs to be replaced. You
should replace the battery every five
years, or before leaving home for an
extended period.
