Programming Keypad Lock
NOTE: In order for the lock function to work as described below, the "LOCK" function must have been enabled during
installation. If the Lock function does not seem to work, you must change a dip switch located on the back of the
thermostat. See “CHANGING DIP SWITCH SETTINGS” section to turn the “LOCK” function on.
This thermostat has a keypad lock that will prevent unauthorized program changes. When the keypad is locked, the
user must enter the 3-digit combination or the keypad will not allow programming changes.
IMPORTANT: Please write down your chosen 3-digit combination in a convenient location away from the thermostat.
The thermostat WILL NOT let you change the settings or the mode if you forget the combination. When the
thermostat "LOCK" function is on, only the LOCK keypad button is functional until the thermostat is unlocked.
