Step 5. Connect wires to ecobee
3
If you are replacing an existing thermostat, use the stickers as
a guide when inserting the wires into ecobee
3
terminal blocks.
The wires from the wall should plug easily into the terminal
blocks. To release a wire, press down on the lever.
When installed correctly, the back of the terminal block
will be down. Give each wire a little tug to ensure it is
secured.

If you installed the PEK in step 3,
the R (or Rc or Rh) always connects to
the Rc terminal on the ecobee

.
You do not need to jumper Rh or Rc –
ecobee
3
does it automatically.
