T7200D,E SERIES 2000 COMMERCIAL MICROELECTRONIC THERMOSTATS
Do not install the thermostat where it can be affected by:
—
drafts, or dead spots behind doors and in corners.
—
hot or cold air from ducts.
—
radiant heat from sun or appliances.
—
concealed pipes and chimneys.
—
unheated (uncooled) areas such as an outside wall
behind the thermostat.
Mounting Wallplate
The wallplate mounts horizontally on the wall or on a
2 in. x 4 in. wiring box. Position the wallplate horizontally
on the wall or on a 2 in. x 4 in. wiring box.
1. Position and level the wallplate (for appearance
only). The thermostat functions properly even when
not level.
2. Use a pencil to mark the mounting holes. See Fig. 2.
3. Remove the wallplate from the wall and drill two
3/16 inch (4.8 mm) holes in the wall (if drywall) as
marked. For firmer material such as plaster or wood,
drill two 7/32 inch (5.5 mm) holes. Gently tap
anchors (provided) into the drilled holes until flush
with the wall.
4. Position the wallplate over the holes, pulling wires
through the wiring opening.
5. Loosely insert the mounting screws into the holes.
6. Tighten mounting screws.
CAUTION
Electrical Shock Hazard.
Power source can cause electrical shock.
Disconnect power before wiring to prevent
electrical shock or equipment damage.
1. Loosen the terminal screws on the wallplate and
connect the system wires. See Fig. 3.
IMPORTANT
Use 18-gauge, solid-conductor color-coded
thermostat cable for proper wiring. If using
18-gauge stranded wire, do not use more than
ten wires. Do not use larger than 18-gauge wire.
2. Securely tighten each terminal screw.
3. Push excess wire back into the hole.
4. Plug the hole with nonflammable insulation to
prevent drafts from affecting the thermostat.

WIRING WALLPLATE
All wiring must comply with local electrical codes and
ordinances. Follow equipment manufacturer wiring
instructions when available. Refer to Fig. 4 and 5 for
typical hookups. A letter code is located near each
terminal for identification.
