You can use a maximum of 300 ft (91.44 m) of wire for connecting the Indoor Flush Mount Temperature sensor to the thermostat.
Follow these steps to install the indoor flush mount sensor:
1. Drill a ½" hole into the drywall where you want to install the sensor.
2. Fish the cable that connects to the sensor from behind the drywall and out through the ½" hole so that 6" - 12" of the cable
hangs through the hole.
3. Feed the sensor wire through the center of the threaded outer case of the sensor and connect it to the cable that is hanging
through the hole in the wall as shown in FIG. 15.

4. Carefully feed the wires and wire-nuts through the ½" hole and into the wall. Use your hands to lightly screw the threaded
outer case into the hole in the wall as shown in FIG. 16.

5. Use a screwdriver to screw the threaded outer case of the sensor the rest of the way into the ½" hole in the drywall. Be careful
to not pinch the wire while you are screwing in the case. Screw the case into the wall until the front surface of the case is
inserted just past the surface of the drywall.
6. Use your thumb to carefully push the sensor body into the threaded outer case until the face of the sensor body is flat against
the drywall.
7. Attach the connecting wires from the sensor to the S1 and S2 terminals on the thermostat (see FIG. 13). It does not matter
which wire you connect to either terminal.
