About Advanced Features & Operation
29
ENERGY SAVING SMART FAN -  This feature automatically de-energizes 
the fan during an Unoccupied time period, except when necessary to heat 
or cool (see page 28). 
Note:  The fan will not de-energize during an Unoccupied time period if it has 
been programmed for continuous operation (step #7, page 20).
HEAT/COOL DIFFERENTIAL - The Heat and Cool setpoints will not be 
allowed to come any closer to each other than the value set in Advanced 
Setup step #9, on page 20. This minimum dierence is enforced during 
Auto-changeover and Program On operation.
Note:  To increase the spread between the heating and cooling setpoints 
in the Auto-changeover mode press the MODE button until only the heat 
setpoint is displayed; adjust to the desired setpoint. Press the MODE button 
until only the cool setpoint is displayed; adjust to the desired setpoint. Press 
the MODE button again to enter the Auto-changeover mode where both the 
heat and cool setpoints are displayed.
