Most Heat Pump
systems have the C wire
and the thermostat can be
power by the 24VAC from
the HVAC system.
Batteries are not
required
for 24VAC powered systems.
If there is not a C wire
installed, the thermostat
MUST be powered from
batteries.
Connect the R wire to either
the RC or RH terminal.
DO NOT REMOVE THE
RC/RH JUMPER

Connect the wires as marked from the HVAC
system to the corresponding terminals on
the thermostat back.
*C wire (24VAC common) Heat Pump
systems usually have the C wire connected
to the thermostat. If there isn’t a C wire,
batteries must be installed.
** O (Orange) or B (Brown) wire (changeover
valve) connect to the W2/O terminal on the
thermostat.
NOTE: Be sure to set the correct changeover
operation (O = changeover with Cool, B =
changeover with Heat) in the SETUP menu.
Connect the R wire to either RC or
RH terminal.
