Honeywell 85-3126 Manuel D’Utilisation
Battery Replacement
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 battery every five
years, or before leaving home for
an extended period.
