Change the batteries

This is normal. Your thermostat works off of a PID loop which enable it to kick on based on previous run times on how long it took to get the temperature up or down to the setpoint. this is so that the desired temperature of the space ie the setpoint is achieved by the time the thermostat is programmed for. This is called "smart technology"

If you turn your heat on and the temperature is set 3 degrees above what the actual temperature of the room, the auxillary heat will automatically come on. The auxillary heat is an electric heat strip that provides heat to your home while the heat pump is in defrost cycle or if there are extremely low temperatures outside. Try not to set the temperature more than 2 degrees above the actual temperature of the room. Hope this helps.
