Battery Replacement
Push excess wire back into the wall opening. Plug
wall opening with non-flammable insulation.
Remove factory-installed jumper
only for two-transformer systems.
Wiring
Connect the common side of the
transformer to “C” terminal. This
connection is mandatory.
Power Requirements
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.
Remove tab.
The TouchPRO Wireless thermostat is shipped
from the factory with the coin cell installed. To
keep the battery from discharging during shipment
and storage, the TouchPRO Wireless thermostat is
shipped with a plastic tab inserted in the battery
holder. This tab must be removed during installation.
Simply pull the plastic tab out of the battery tray.
Make sure that the battery tray is fully inserted into
the TouchPRO Wireless thermostat.
Coin cell
battery tray
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.
