Step 14
Carefully push the wired connections back into the JBOX.
Step 15
Mount pre-wired 16 gauge SS6000 backplate on top of JBOX adapter, using four #5 ½” coarse
thread screws. See Figure 8.
Figure 8: Backplate on Adapter Plate
Step 16
Ensure no airflow from JBOX or wall cavity is able to seep into the thermostat through the wire
harness. Telkonet recommends the use of UL caulk or UL rated insulating tape as shown in
Figure 9 to avoid false temperature readings.
