displayed, you can clear it by pressing the SERVICE button.
HUMD MX indicates the humidifier has not reached the current humidity setting in the last

In cooling, as the room temperature falls you will eventually reach the setpoint temperature.

continue to call for cool as the temperature decreases in the following manner. 78.9, 78.8,
78.7, 78.6, 78.5, 78.4, 78.3, 78.2, at approximately 78.2 the thermostat will quit calling for
