Installing the Smart Thermostat

The ideal location for the Smart Thermostat is
approximately five feet (1.5m) above floor level in the
main living area.
Do not install the Smart Thermostat:
Close to sources of heat such as incandescent lights
or heating/cooling registers.
In direct sunlight.
On exterior, non-insulated or poorly insulated walls.
In the kitchen or other areas of potentially high heat
and/or humidity.
In an area that could restrict air flow.
To Install the Smart Thermostat:
1. Remove the front cover of the Smart Thermostat,
insert a flat-head screwdriver into one of the slots as
shown below and gently twist the screwdriver.
2. Place the Smart Thermostat backplate on the wall.
Make sure that any existing wires can be inserted
