Step 4: Label the wires
•
Label only the R, Y/Y1, G, and W/W1 wires with the matching wire labels
provided.
•
If you have more than one wire going into these terminals, label only those
wires going to your thermostat.
Note:
If you have wires connected to both R
C and RH terminals at the HVAC
control board, you may have a two-transformer system. Contact our
