LOW BATTERY WARNING - The two AA lithium batteries must be replaced
Important: To ensure proper operation use only AA LITHIUM batteries.
When the “low battery” icon is displayed the batteries must be replaced
immediately (see next page). The manufacturer cannot be liable for
improper operation of the thermostat if the batteries are not immediately
replaced. Annual battery replacement is especially critical in locations
subject to freezing temperatures. The thermostat will be unable to turn
on the heating system if the batteries are exhausted.
