Battery Replacement
The TouchPRO Wireless® thermostat 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.
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.
