The Thermostat can be externally powered with a power
source rated from 12V to 24V, AC or DC, at 100ma or
greater If used, connect to the C and RH terminals (no
polarity)
The 24VAC "C" wire is the other side of the 24VAC heating
transformer and can be found where the other thermostat
wires connect at the wall or at the furnace Do not use the
common or ground side of the line voltage
The Thermostat runs on 4 AA alkaline batteries, the C wire
(if available), or both batteries and the C-wire If you do not
have a C wire, you can run a new wire from the HVAC or
use a standard 12-24V [AC or DC] wall transformer
The C-wire is optional but preferred for all installations
