To quote AHSRAE 90.1-2007 Addendum cr:
temperature control throttling range: The number of degrees that room temperature must change in order to go from full heating to no heating or from full cooling to no cooling.
unmet load hour: an hour in which one or more zones is outside of the thermostat setpoint plus or minus one half of the temperature control throttling range. Any hour with one or more zones with an unmet cooling load or unmet heating load is defined as an unmet load hour.

For reference, the Commercial Reference Building Models use a reporting tolerance of 0.556 deltaC, or 1.0 deltaF.
