KEYPAD LOCKOUT: You can lock the front panel buttons to prevent unauthorized
tampering of your thermostat settings.
NOTE: These keypad lock instructions need to be performed in a timely manner,
as the thermostat will timeout and automatically exit the keypad lock screens
and return to the Normal Run screen after approximately 10 seconds without a
button press.
TO LOCK THE KEYPAD: Start with the System Mode switch in either the HEAT or
COOL positions, and the Set Slide switch in the RUN position. Press and hold the
NEXT button for 5 seconds, and the words “LOCK CODE” then “SET CODE” will
appear at the top of the screen. Select a 4-digit code that you would like to use
for locking the thermostat. Press the UP/DOWN buttons to change each flashing
digit, using the NEXT button to cycle through which digit is flashing. Press and
hold the NEXT button for at least 5 seconds. The thermostat will return to the
Normal Run screen, with a padlock shown to confirm that the thermostat is now
locked.
TO UNLOCK THE KEYPAD: Press and hold the NEXT button for 5 seconds, and the
words “ENTER CODE” will appear at the top of the screen. Enter the proper
unlock code that was used for initially locking the thermostat. Press the
UP/DOWN buttons to change each flashing digit, using the NEXT button to cycle
through which digit is flashing. Press and hold the NEXT button for at least 5
seconds. The thermostat will return to the Normal Run screen without the
padlock, and the thermostat is now unlocked.
IF YOU FORGET YOUR KEYPAD LOCK CODE: The following steps can regain access
to the thermostat. Place the Set Slide switch in the RUN position. On the back
of the thermostat’s circuit board, press and hold the “HW RST” (Hardware Reset)
button for 2 seconds and release. The thermostat will perform a reset and
should now be unlocked. If the thermostat is still locked with the padlock
present, perform the “To Unlock The Keypad” shown above using “0000” as the
code.
