Making 4 Wires Work When 5 Wires Are Required
If you would like to install the thermostat using only 4 wires when 5 are
required, follow the directions below. You will need a screwdriver along with a 3"
long piece of thermostat wire to use as a jumper:
1. Make sure the power is off.
2. Label and disconnect wires at the thermostat. Please note the color and
corresponding wire designator with each color. For example: The R wire is
red and the W wire is white and so on. You will need this information handy
for the next step at the HVAC equipment.
3. At the HVAC equipment end of the thermostat wires (usually at the furnace),
locate the terminals that the wires are attached to.
4. Remove the “G wire” from the terminal marked G.
5. Place the “G wire” on terminal C.
6. Place one end of the 3" long jumper on terminal G.
7. Place the other end of the 3" long jumper on terminal Y. Please note that
there will be more than 1 wire on terminal Y.
8. When connecting the wires to the thermostat, note that the wire
that was previously connected to the G terminal of the old thermostat
will now be required to be connected to the C terminal on the
thermostat.
All other wires
will be connected such that the connections on
each end of the individual wires match terminal designations.
For example: Connect the yellow wire on the thermostat end to the Y terminal
on the thermostat. The yellow wire will be connected to the Y terminal on the
HVAC equipment end also.
