2. INSTALLATION
The thermostat is typically mounted to an industry standard double gang
junction box or trim ring about 5 feet above the floor. Example Legrand
part numbers are shown in the chart below.
Thermostats should be placed away from windows to avoid solar heating
to improperly affect the units temperature sensitivity. Be certain that the
thermostat will not be covered by objects such as a bathroom or closet
door when open. The thermostat should not be mounted near the heating/
cooling equipment in a manner where direct airflow, or the waterfall effect
of a heating or cooling unit would impact the measurement of the overall
room.
