Step 7. Connect Wires to New Wallplate (Cont)

M22246

If wires will be connected to both R

and R on the new thermostat,

remove metal jumper wire between R

and R. Leave metal jumper

wire in place if only one of the terminals, R

or R, will be connected

on the new thermostat.

If wires were connected to both R and RH terminals on the old
thermostat, remove metal jumper wire between R

and R on the

new thermostat. Connect the old R to the new R

and the old RH

to the new R.

If two C and/or C1 wires were connected to the old thermostat, do
not connect them to the new thermostat. Wrap the bare end of
each wire separately with electrical tape and do not use.

If one C and/or C1 wire was connected to the old thermostat, the
wire should be connected to the "C" letter designation on the new
thermostat.
