Maintaining Your Thermostat
INSTALLING BATTERIES
IMPORTANT
Batteries must be installed for programming and operation of the thermostat and heat- ing/cooling system.
1.Purchase two AA alkaline batteries; nonalkaline batteries do not last as long, and can leak, causing damage to the thermostat or wall surface. We recommend Energizer® batteries.
2Make sure the thermostat is set in the OFF position.
3.Use a coin to remove the battery door.
4.Install the fresh batteries, making sure the positive and negative terminals are oriented correctly.
5.Replace the battery door.
As the batteries are running low, the bAt Lo indicator flashes for one to two months before the batteries run out completely. Replace the batteries as soon as possible after the indicator starts flashing.
