Wiring—conventional system About your new thermostat

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.
