FOREWORD
This addendum is to allow cooling-only terminal units to provide heating in occupied, warm-up, and setback modes if the air handling unit supply air temperature is greater than room temperature.
Note: In this addendum, changes to the current guideline are indicated in the text by underlining (for additions) and strikethrough (for deletions) unless the instructions specifically mention some other means of indicating the changes.
