Your Pre-set Temperatures

The sleep timer will automatically change the thermostat from the Sleep to Home temperature after the number of hours set in 
the configuration menu. The Sleep timer default is 8 hours and can be changed to a setting between 1 to 12 hours.
Example: You have selected 8 hours for the Sleep timer in the configuration menu. Press the Sleep button, the thermostat will 
maintain the sleep temperature for 8 hours. After 8 hours the thermostat will go back to the Home temperature. The Sleep timer 
will be activated each time the sleep button is pressed.

The thermostat can display a reminder when it is time to change the air filter on your heating and cooling system. The Change 
Filter will automatically display after the number of hours set in the configuration menu. The change filter reminder time default 
is 200 hours and can be changed to a setting of 25 to 1975 hours; 200 hours is approximately 3 months.
Example: You have selected 250 hours for the change filter reminder. The thermostat will display change filter after 250 it has 
counted down 250 hours. When 

“Change Filter” is displayed, press the 

 or 

 button to clear the display and restart the 

timer.

With Cool Savings enabled, the thermostat will make small adjustments to the desired temperature during periods of high 
demand to reduce cooling system running time and save energy. When the cooling system has been running for more than 
20 minutes, humidity in the home will be lower and a higher temperature will feel comfortable. After 20 minutes of run time, 
the thermostat will start increasing the desired temperature in steps of less than one degree as the system continues to run. 
These adjustments will eventually cause the system to satisfy the thermostat and turn the system off to reduce the energy 
consumption. When the Cool Savings feature is active and making adjustments, the display will flash “Save”. The amount of 
adjustments to the desired temperature is dependent on the Cool Savings value that is set, 1 being the least adjustment and 6 
being the most adjustment. With this feature set to OFF, no change will occur when the cooling system is continuously running 
during the periods of high demand. Periods of high demand will normally occur during the late afternoon and early evening on 
the hottest days of the summer.
