Wall Modules
BEFORE INSTALLATION
Cover Disassembly
Two locking mechanisms are used on the cover of the wall
module. After installation, to disassemble the cover and the
subbase see Fig. 1.
Fig. 1. Cover disassembly.
CAUTION
Erratic System Operation Hazard.
Failure to follow proper wiring practices can
introduce disruptive electrical interference (noise).
Keep wiring at least one foot away from large inductive
loads such as motors line starters, lighting ballasts,
and large power distribution panels.
Shielded cable is required in installations where these
guidelines cannot be met.
Ground shield only to grounded controller case.
IMPORTANT
All wiring must comply with local electrical codes
and ordinances or as specified on installation
wiring diagrams.
— Wall module wiring can be sized from 14 to 22 AWG
(2.0 to 0.34 sq mm) depending on the application.
— The maximum length of wire from a device to a wall
module is 1000 ft (305m).
— Twisted pair wire is recommended for wire runs longer than
100 ft (30.5m).
— The cover for the wall module is packed separately from
the subbase for ease of installation.
See Fig. 2 to release/replace the subbase terminal block.
Fig. 2. Releasing/replacing terminal block.
INSTALLATION
Mount the T7770A,B,C,D,E,F,G Wall Modules on an inside
wall approximately 54 in. (1372 mm) from the floor (or in the
specified location) to allow exposure to the average zone
temperature. Do not mount the wall modules on an outside
wall, on a wall containing waterpipes or near air ducts. Avoid
locations that are exposed to discharge air from registers or
radiation from lights, appliances, or the sun.
The wall modules can be mounted on a wall, on a standard
utility conduit box using No. 6 (3.5 mm) screws or on a 60 mm
wall outlet box (see Fig. 3). When mounting directly on a wall,
use the type of screws appropriate for the wall material.

conduit box or 60 mm wall outlet box.
See Fig. 4 for subbase mounting dimensions.
Wiring
Attach the wires from the device sensor terminals to the
appropriate wall module terminals. See Fig. 5 through 16.
NOTE: None of these wall modules are compatible with
W7751A,C,E,G Controllers.
CAUTION
Improper Electrical Contact Hazard.
Screw type terminal blocks are designed to accept
no more than one 14 AWG (2.5 sq mm) conductor.
Connect multiple wires that are 14 AWG (2.5 sq mm)
with a wire nut. Include a pigtail with this wire group
and attach the pigtail to the individual terminal block.
Wiring Modules Without a Removable Terminal Block
Attach the wires as follows:
1. Connect controller sensor leads to the sensor screw
terminals.
NOTE: T7770A1006 have a 20K ohm sensor,
T7770A3002 have a 10K ohm sensor. They
are for use in averaging for the T7350. They do
not have E-bus network terminals.
2. If the module has E-bus terminals, connect the
controller E-bus leads to these screw terminals.
NOTE: Wire the E-Bus using Level IV 22 AWG
(0.34 sq mm) plenum or non-plenum rated,
unshielded, twisted pair, solid conductor wire.
NOTE: Unless otherwise noted, sensor and E-Bus
terminals are not polarized; reversing the two sensor
leads does not affect the signal.
Wiring Modules With a Removable Terminal Block
Wire the terminal blocks as follows:
1. For single wires, strip 3/16 in. (5 mm); for multiple wires
going into one terminal, strip 1/2 in. (13 mm) insulation
from the conductor.
2. If two or more wires are being inserted into one
terminal, twist the wires together before inserting.
NOTE: When two or more wires are being inserted
into one terminal, be sure to twist them
together. Deviation from this rule can result
in improper electrical contact. See Fig. 17.
3. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
4. Verify wall module wiring with Fig. 5 through 16.
NOTE: Wire the E-Bus using Level IV 22 AWG (0.34 sq mm)
plenum or non-plenum rated, unshielded, twisted
pair, solid conductor wire.
