Replace the batteries as soon as possible after
the indicator starts flashing.
After the batteries are completely dead, the
bAt Lo indicator disappears, leaving the display
completely blank and the heating and/or
cooling system not operating.

batteries do not last as long.
• Make sure the thermosat is set to the OFF
position.
• Use a coin to remove the battery door.
