Use of Lithium AA Batteries
I am a new user and just starting to install my system. I am concerned about the battery life of the keypad which is said to be 8-12 months. I am not at this location for part of the year (sometimes 6 or more months) and during the winter, battery life can be compromised. The house thermostat is set for 55 degrees minimum when we are not here. The instructions say that the keypad takes 2 AA alkaline batteries. Can I use Lithium AA batteries instead?
