6.2. SWING SETTING
A thermostat works by turning your heating or
cooling system on and off whenever the room
temperature varies a certain number of degrees
from the set-point temperature. This variation is
the "swing." Your system should cycle on about 3
to 6 times per hour. A smaller swing number
increases the number of cycles, so room
temperature is more constant. A larger swing
number decreases the number of cycles, saving
energy in most cases. To change the SWING value
from the main menu:
• Use UP/DOWN ARROW to change the flashing
temperature setting for MON EVE.
• Touch YES to accept the displayed temperature
and advance to Set MON NITE start time.
• Use the UP/DOWN ARROW to change the
flashing start time for MON NITE.
