Connect Thermostat Wires
Once the mounting plate is fastened to the wall, the next step is to connect the wires.
  • Match the color coded wires to the appropriately marked terminal connections on the thermostat and tighten to the terminal screws.
  • If the old wires had no color, connect them to the appropriate terminal based on the labeling you marked when you removed the old thermostat.
  • Refer to the digital picture you took if necessary.
  • Once the wires are connected, push excess wires into the wall.
