Before you begin using your thermostat, you should be familiar
with its features and with the display and the location and
operation of the thermostat buttons. Your thermostat consists of
two parts: the thermostat cover and the base. To remove the
cover, gently pull it straight out from the base. To replace the
cover, line up the cover with the base and press gently until the
cover snaps onto the base.
Now that you are familiar with the thermostat buttons and display,
read the following information to learn about the many features of
the thermostat.
