Never attach wires to both the O and B terminals on the CT3611. If the old thermostat had wires on both the O and B
terminals, be sure to attach the B wire to the CT3611 C terminal. If another wire is already matched to the C terminal,
contact Honeywell.
b
If the old thermostat had separate wires on both the V and VR terminals, some system modification is required. Call
your local heating and cooling contractor for assistance.
c
If the old thermostat had wires on W1, Y1 and W2 terminals, then remove the CT3611 factory-installed jumper
between Y and W1 terminals and match the old W1 to W1, Y1 to Y and W2 to W2.

Use electrical tape to tape off the end of the wire and push the taped end back into the wall wiring hole.
