Batteries
Two “AA” alkaline batteries are included with your thermostat. Prior to use, open the battery door and remove the battery tag. We recommend replacing batteries every 2 years, for best results, use new premium brand alkaline batteries such as Duracell® or Energizer®. When battery power remaining is
approximately half, the

!CAUTION
If the home is going to be unoccupied for an extended
period (over 3 months) and 
is displayed, the batteries should be replaced before leaving. When less than two months of battery life remain, the setpoint temperature will change by 10 degrees (10 degrees cooler in Heat / 10 degrees warmer in Cool) to alert you to change the batteries before they fail. If the temperature change occurs, the normal setpoint can be manually reset. However, the temperature will change by 10 degrees within two days if the batteries are not replaced.
!WARNING
Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard.
Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will damage
thermostat and could cause personal injury and/or property damage.
Thermostat installation and all components of the system shall conform to Class II (current limited) circuits per the NEC code. Failure to do so could cause a fire hazard.
