INSTALLATION INSTRUCTIONS
BEFORE INSTALLATION
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring diagrams.
Wall module wiring can be sized from 16 to 22 AWG (1.5 to
0.34 mm
length of wire from a device to a wall module is 1000 ft (305
m). Twisted-pair wire is recommended for wire runs longer
than 100 ft (30.5 m).

INSTALLATION
The C7110D packages include two setpoint dials. By
default, the “Celsius Relative” type is mounted. This can be
easily replaced with the “Celsius Absolute” type by pulling
the one dial off and inserting the other one.
Mount the C7110C,D Wall Modules on an inside wall
approx. 54 in. (1.3 m) from the floor (or in the specified
location) to allow exposure to the average zone temperature.
NOTE: Maintain a mounting clearance of approx. 4 in.
(10 cm) to the left-hand side of the module in
order to allow a free airflow for the temperature
sensor and accessibility of the setpoint dial.
Do not mount the wall modules on an outside wall,
on a wall containing water pipes, or near air ducts.
Avoid locations exposed to discharge air from
registers or radiation from lights, appliances, or
the sun.
Keep wiring at least one ft (305 mm) away from
large inductive loads such as motors, line starters,
lighting ballasts, and large power distribution
panels.
Run wall module wiring separately from 50 Vac or
greater power wiring.
The wall modules can be mounted on a 60-mm wall outlet
box using No. 6 (3.5-mm) screws or on a wall (see Fig. 2).
When mounting directly on a wall, use the type of screws
appropriate for the wall material.
See Fig. 2 for C7110C,D mounting dimensions.

Mounting Procedure
1. Disassemble the cover as is shown in Fig. 1.
2. Remove the setpoint dial by pulling it off.
3. a) Mount the wall module onto the wall outlet box,
or
b) bore wall holes as is specified in Fig. 2 and mount
the wall module with appropriate screws.
4. Connect the wires to the terminal block according to the
specifications in section "Wiring".
5. Insert the setpoint dial and turn it clockwise as far as
possible.
6. Make sure that the dial's position is such that the 30
(Celsius absolute scale) or the +5 (Celsius relative
scale) point to the right-hand side of the wall module
(see Fig. 3).

Wiring
Attach the wires from the device sensor terminals to the
appropriate wall module terminals. See Fig. 5.
IMPORTANT
Screw type terminal blocks are designed to accept
no more than one 16 AWG (1.5 mm2) conductor.
Wire the terminal blocks as follows:
1. Strip 3/16 in. (5 mm) of insulation from the conductor.
2. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
3. Verify wall module wiring with Fig. 5.
