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 model). When the safe wait time has elapsed, the message stops flashing and the compressor turns on.

CAUTION
Equipment damage hazard
To prevent possible compressor damage, do not operate cooling system when outdoor temperature is below 50°F (10°C).

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. The settings are stored in non-volatile (permanent) memory and are thus preserved when the thermostat is without batteries.
