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.

7.2. SMART RECOVERY SWITCH #2  
The Program Lock allows the owners/operators to  
prevent unauthorized changes to the thermostat’s  
settings. When the thermostat is locked, a three  
digit code is set (000 to 999). That code must be  
re-entered before locked settings can be changed  
without performing a hardware reset of the unit.  
The status of the lock is indicated by an open or  
closed padlock icon.  
Smart Recovery allows your HVAC system to  
attempt to recover from a setback period and  
reach your desired comfort temperature set point  
by the beginning of your programmed comfort  
period. This option allows you to choose whether  
to use Smart Recovery.  
When enabled, Smart Recovery will initiate if:  
• Recovery is from an evening setback to  
morning comfort or day setback to evening  
comfort period.  
• In Heat mode the temperature set point of the  
comfort period must be higher than the setback  
period.  
• In Cool mode the temperature set point of the  
comfort period must be lower than the setback  
period.  
• The estimated Smart Recovery time must be  
longer than 15 minutes for a Smart recovery to be  
initiated.
