WARNING
Hazardous voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure the power cannot be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
NOTICE
Equipment damage!
Applying excessive voltage to the thermostat can permanently damage it.
Note:
Terminal blocks are included with the mounting hardware contained in a small plastic bag (new
installation) or remove terminal blocks from pin header (existing installation).
To wire the thermostat:
6. Connect the wires to the terminal block(s) by:
a. Removing approximately 1/4 inch (6 mm) of insulation from the wires.
b. Using the terminal block screws to securely fasten each wire into the terminal block.
Note:
Refer to
and the wiring diagrams on page
through
to determine the
correct terminal for each wire.
In some cases the terminal labels (such as Y, G, or R) correctly correspond to the first
letter of the color wire in which they are connected. However, it is important to verify
which equipment terminals are connected at the other ends of the wires before
connecting the wires to the thermostat.
7. Align the pins/label on the circuit board with the holes/label on the terminal blocks and gently push the
wired terminal blocks into place on the circuit board (refer to
Figure 3.
Attaching the wired terminal blocks to the pins on the circuit boards
8. Push the excess wire through the hole in the wall cavity or into the junction box.
Important:
Do not coil excess wire between the thermostat and the backplate. Use non-flammable
insulation to prevent air movement between the wall cavity and the thermostat.
