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. If the filter reminder is turned on during installation, the words Change Filter will flash on the screen when the filter needs to be replaced. After you replace the air filter, press and hold the RUN button for 3 seconds to reset the alert.

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
