Figure 4. Feeding Wires through Back Plate
4. If you are mounting the back plate directly to a wall surface, hold the back plate against the
surface and mark the fastener locations.
5. Secure the back plate using appropriate fasteners. (See “Mounting Surfaces,” p. 9.)The
thermostat must be level and plumb for accurate temperature control and to ensure proper air
mo
vement through the thermostat enclosure.
Wiring
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 will permanently damage it.
General Practice
To wire the thermostat:
1. Connect the wires to the terminal block(s) packaged in the box with the thermostat. (The
programmable
thermostat has two terminal blocks, the non-programmable thermostats have
only one):
• R
emove approximately 1/4 inch (6 mm) of insulation from the wires.
• Use the terminal block screws to securely fasten each wire into the terminal block.
• Refer to the section, “Terminal Identification,” p. 13 and the wiring diagrams on the pages
that follow to determine the correct terminal for each wire.
Note: In
some cases the terminal labels (Y, G, R, etc.) correctly correspond to first letter of the
color wire to which they are connected. However, you must verify which equipment
terminals are connected at the other ends of the wires before connecting the wires to
the thermostat.
