Sensor Wiring
The connection between the Duct Sensor and the
thermostat must be wired per the connection diagram.
Only three conductors are used, therefore the extra
conductors should be cut from each end of the cable to
prevent shorting. Follow the color coding as shown.
WARNING
Turn off power to the thermostat before wiring. Death
or injury from electric shock could result.
