A Note About Auto Changeover:
In Auto you have the ability to switch between Auto Heat or Auto Cool
by pressing the system key. This can be done once the current mode has
reached its setpoint. For example: if in Auto Heat, the heat setpoint must
be satisfied before the thermostat will allow you to switch to Auto Cool.
You can switch out of Auto by holding down the system key. To get back
into Auto, you must toggle the system key to Auto.
