If you insert new batteries within 20 to 30 seconds of removing the old ones, the thermostat does not require repro- gramming. However, if the display is blank, the batteries are dead or incorrectly installed and the thermostat requires reprogramming.
AM and PM indications are correct. Make sure the current day and time are correct. Reprogram if necessary. Check that the green LED is lit. Check that the switch on the thermostat is set to HEAT. Check the system fuse or circuit breaker and replace or reset, if necessary.
