To Enter the Advanced Configuration Mode:
Press and hold the FAN key for about 10 seconds until the display changes so that only two pairs of digits are showing. The large upper display shows the configuration number and the small lower shows the configuration setting. Configuration number will be flashing, which means it can be adjusted using the UP and DOWN keys. To cause the opposite pair to flash (to be adjustable), press the MODE key. Successive presses of the MODE key alternate between the configuration number and the configuration setting. To exit the configuration mode, press the FAN key. If no key is pressed for 3 minutes, the configuration mode will automatically exit, returning the thermostat to normal operation (all previous changes will be saved).
