CHANGING BATTERIES

When 1)the battery symbol on the LCD display flashes, or 2) Temperature is in flashing and a beep sound

is heard from the unit, it indicates that the batteries are running low and have to be replaced immediately.

However, it is recommended that the batteries be replaced every year even if the indicator is not flashing.

To replaced batteries:

- Set the thermostat system switch to the OFF position and have the new batteries on-hand.

- Open the thermostat by gently pulling the front of the thermostat away from the backplate.

- Remove the old batteries and install new ones quickly.

- Close the thermostat to its original position.

If new batteries are inserted within 20 seconds of removing the old ones, the existing time and programs will

not be cleared. Otherwise, the display will show 9:00AM and the thermostat will have to be re-programmed.
