<DIV><SPAN class=365164323-23082006><FONT face=Arial color=#0000ff size=2>This
diagram shows the relationship among throttling ranges, set point temperatures,
and dead band. Personally, I didn't get the concept of throttling range
until I digested this diagram.</FONT></SPAN></DIV>

<DIV><SPAN class=365164323-23082006><FONT face=Arial color=#0000ff
size=2>Essentially, throttling range is the temperate range over which a heating
system is heating a space or cooling system is cooling a space. For
example, if your setpoint for heating is 72F and your throttling range is 4F,
then the system will start heating when the temperature drops to 70F and
continue heating until the space temperature reaches 74F (a 4 degree range).

<DIV><SPAN class=365164323-23082006><FONT face=Arial color=#0000ff size=2>How
the system heats or cools depends on the system type (but that is another
topic).</FONT></SPAN></DIV>
