User's Manual

When the AA batteries are low and need to be replaced the low battery symbol will appear on the

LCD screen and a beep will sound every hour. However, it is recommended that the batteries be

replaced every year, even if the battery symbol does not appear.

To replace the batteries:

Select OFF to change the thermostat to OFF mode

Remove the thermostat from its mounting plate (back cover) carefully

Remove the old AA batteries and install new ones

Place the thermostat back into its original position

Note: If the batteries are low the backlight will not turn on and the remote control feature will not

work. After changing the batteries, complete the LEARN PROCEDURE again to connect the

thermostat and remote sensor / transmitter. (see the remote sensor/transmitter section)

The backlight helps you to clearly see the thermostat display at night. However, frequent backlight

use will reduce your battery life. To disable the backlight see the “Optional Settings” section.
