Alternate wiring (conventional systems)
If labels do not match terminals, connect wires as
shown here (see notes, below).
Remove metal jumper connecting
R
and
Rc
only
if you must connect both
R
and
Rc
wires.
If your old thermostat had both
R
and
RH
wires,
remove metal jumper. Connect the
R
wire to the
Rc
terminal, and the
RH
wire to the
R
terminal.
If your old thermostat had only 1
C
or
C1
wire, connect it to the
C
terminal. If your old
thermostat had 2
C
or
C1
wires, wrap each
separately with electrical tape and do not
connect them.
