in Timer operation.
It allows you to “override” the reset timer
setting until the beginning of the next Timer
period.
For example, if the furnace is ON, pressing
the “Override” button will turn the furnace OFF
until the next period. If the furnace is OFF,
pressing the “Override” button will turn the
furnace ON, and allow you to select a
temperature setting, until the next period. The
furnace will remain on until the next timer
period or until the Override function is turned
off.
