OPERATION
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, pull it straight out from the base. To replace the cover, line
up the cover with the base and press until the cover snaps onto
the base.
