LOW BATTERY WARNING

The two AA lithium batteries must be replaced at least once every 12 months to ensure proper operation. The “low battery” icon (fig. 1) will appear on the display when it is time to replace the batteries. When the “low battery” icon is displayed the batteries must be replaced immediately. The manufacturer cannot be liable for improper operation of the thermostat if the batteries are not immediately replaced.
