If you are going to be away from a home in the winter, and the thermostat has batteries, be sure to replace the batteries on a regularly. If a thermostat with batteries stops working because the batteries went dead, water pipes could freeze and break causing an extreme amount of damage. It would be worth it to use lithium batteries.
