Replacing Batteries
Not all thermostat models require batteries.
If the thermostat has batteries, a low battery warning flashes on the main screen for approximately 30 days.
NOTES:

• If batteries are not replaced the Low Battery warnings flash, the LO batt screen displays continuously and the thermostat stops operating batteries are replaced.
• The thermostat has a low battery indicator. However, it is recommended that you replace the batteries once each year. Do this to prevent leakage and prevent the thermostat and HVAC system from shutting down due to a lack of thermostat battery power.

Replace the batteries as follows:

1. Remove the thermostat from the base by pulling it straight out.
2. Install three new AAA alkaline batteries with proper polarization.
   NOTES:
   • Always use AAA alkaline batteries.
   • All programming (Schedule, Date and Time) information is retained during battery replacement.
3. Place the thermostat back on its base by aligning the terminal screw blocks with the pins on the back of the thermostat.
4. Push the thermostat straight onto the base.

  • Pressing OVERRIDE sets the temperature to the Occupied setting for the selected time. The next Unoccupied period switches back to the program settings.
  • To cancel the temperature override and follow the programmed schedule, press CANCEL.
  • To unlock the screen, see the Advanced Settings section.

Temperature Recovery
The thermostat is equipped with a feature to eliminate guesswork when setting a schedule. That is, the user need not know the amount of time for the HVAC system to bring the space to temperature (without overshoot) before the scheduled time. The thermostat manages that automatically. Simply set the program schedule to the desired time to have the space at a comfortable temperature. In addition, program the temperature to this comfort temperature.
The thermostat activates the heating or cooling at the proper time to reach the scheduled temperature at the scheduled time.
NOTE: The setpoint changes gradually to use economical stages and avoid overshoot.
For example, space will be occupied at 8:00 AM and the desired temperature is 70°F. Set the OCC 1 period for 8:00 AM and 70°F. The thermostat turns on the heat prior to 8:00 AM to raise the temperature to 70°F by 8:00 AM.
The thermostat provides an alert that the heating or cooling system is coming on before a scheduled time by displaying “Recovery”on the screen.

Setting Calendar This thermostat is designed to, under normal use, automatically keep current time and day in memory for up to ten years once the calendar is set. There are two ways to set the calendar for this thermostat:

• SETTING CALENDAR AFTER THERMOSTAT IS ALREADY FUNCTIONING
  See steps 1 through 4, in the Advanced Settings section, to set year, month and day.
• SETTING CALENDAR WHEN THERMOSTAT IS FIRST POWERED
  When first powered, the thermostat proceeds through a sequence of screens to set the calendar.
