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

Battery replacement

Install two fresh AAA batteries when either Lo Batt or battery icon appears on the screen. The low battery indicator 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 nonvolatile (permanent) memory and are thus preserved when the thermostat is without batteries.
Set the System switch to Off before removing the batteries. Otherwise, the heating/cooling system could remain activated even when batteries are removed.
