Trouble Condition: "TMPR" (Tamper)
SOLUTION TO STANDARD SENSOR - "TMPR" (TAMPER)

TMPR stands for “Tamper” which indicates that your sensor is not sitting in the bracket correctly.

Press on Sensor to check that it is properly installed. If you fixed the issue, the “TMPR” message should disappear. If it continues to read "TMPR" remove the Sensor, wait 10 seconds, and replace Sensor back into bracket. Alternatively, you can check to make sure the tamper switch is working. You can do this by holding down the gray depression switch.
