Built-in compressor protection This feature helps prevent damage to the compressor in your air conditioning or heat pump system. Damage can occur if the compressor is restarted too soon after shutdown. This feature 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). When the safe wait time has elapsed, the message stops flashing and the compressor turns on. Battery replacement Install two fresh AAA batteries when Lo Batt flashes on the screen. Lo Batt appears for 60 days before the batteries are depleted. Replace batteries once a year, or when you will be away for more than a month. Most settings are stored in non- volatile (permanent) memory. Only the clock and the day must be set after you replace the batteries. Pull at bottom to remove thermostat from wallplate. Turn thermostat over, insert fresh AAA alkaline batteries, then reinstall thermostat. Set the System switch to Off before removing the batteries. Otherwise, the heating/cooling system could remain activated even when batteries are removed. RTHXXXX M32707
