Thermostat Power
The thermostat can be powered by either 24VAC from the HVAC system or from four (4) type AA
internal ba eries.
DO NOT
use this thermostat for line voltage controls (120/240VAC).
The C Wire
If the 24VAC common wire (usually blue) is present and is connected to 24VAC common at the HVAC
system end, the thermostat can be powered from the HVAC system and ba eries are not required. If
there is no common wire, ba eries are required.
24VAC Power
Powering the thermostat with 24VAC power
requires
both the 24VAC “C” common wire (typically a
blue wire) and the 24VAC ”R” return wire (typically a red wire).

ery Power
Powering the thermostat from ba eries
does not
require a “C” wire connec on.
DO NOT
install ba eries if the thermostat is powered by 24VAC. They are not required for backup.
If the thermostat is powered by ba eries, the thermostat will operate for approximately (2) two
years on four (4) AA Alkaline ba eries depending on the frequency of user opera ons and backlight
opera on. Always use Alkaline ba eries and replace in complete sets of four (4) at a me.

ery powered, it will
NOT work as a Z-Wave repeater.
CAUTION:
Do not install ba eries and temporarily power the thermostat from 24VAC to include onto
a Z-Wave network. Shortened ba ery life may occur when 24VAC power is removed.
