At hotel rooms, the Setback Temperature Control will be activated when the card key is
taken out. As soon as the card key is inserted again, the normal control will be restored.
Setback Temperature Control works during a predetermined period such as during night
time. The period should be configured by users. The normal control will be restored once
the predetermined period is over.
During a long down time such as during a vacation, the Setback Temperature Control
will remain working as long as the user leaves it on. When turning off the Setback
