Built-in compressor protection This feature helps prevent damage to the com- pressor in your air conditioning or heat pump system. Damage can occur if the compressor is restarted too soon after shutdown. This fea- ture forces the compressor to wait 5 minutes before restarting. During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump model). When the safe wait time has elapsed, the message stops flashing and the compressor turns on. Message flashes until safe restart time has elapsed.9 69-2798EFS—03 M34673 M34676 Set Cool

Battery replacement Install two fresh AAA batter- ies when Lo Batt flashes on the screen. Lo Batt appears for 60 days before the batter- ies are depleted. Replace batteries once a year, or when you will be away for more than a month. The settings are stored in non-volatile (permanent) memory and are thus pre- served when the thermostat is without batteries. Pull at bottom to remove thermostat from wallplate. Turn thermostat over, insert fresh AAA alka- line batteries, then reinstall thermostat.69-2798EFS—03 10 M34673 M34676 Set Cool
