Caution

! Install the unit after all construction work and painting is complete.
! Install the unit in an unobstructed location where there are no objects on the wall

above or below the thermostat or other obstructions (such as furniture) restricting
vertical airflow.

! It is not necessary for the thermostat to be level.

Prior to installing or servicing the thermostat, turn off electricity to the entire
HVAC system; do not turn electricity back on until all work is complete.

Do not jumper wires together to test the system. This may cause harm to your
HVAC system and damage the thermostat, and therefore void the warranty.

All wiring must conform to local codes and ordinances. The distance between
CAT5/CAT5E/CAT6 cables and HVAC cables should be a minimum of one inch.
