Power Supply
General Information
CAUTION
To prevent a risk of injury due to electrical shock
and/or damage to device due to short-circuiting, low-
voltage and high-voltage lines must be kept physically
separate from one another.
NOTE: All wiring must comply with applicable electrical
codes and ordinances. Refer to job or manu-
facturers' drawings for details. Local wiring guide-
lines (e.g., IEC 364-6-61 or VDE 0100) may take
precedence over recommendations provided in
these installation instructions.
NOTE: To comply with CE requirements, devices having a
voltage of 50...1000 Vac or 75...1500 Vdc but lacking
a supply cord, plug, or other means for disconnecting
from the power supply must have the means of
disconnection incorporated in the fixed wiring. This
means of disconnection must have a contact
separation of at least 3 mm at all poles.
Use a min. of 18 AWG (1.0 mm
(2.5 mm 2 ) for all power wiring.
Power is supplied via a removable terminal plug (attached to
terminals 25, 26) allowing individual units to be disconnected
from the power supply without disturbing the operation of
other devices powered by the same source. See Fig. 5.

NOTE: To prevent a risk of short-circuiting and damage to
your unit, do not reverse the polarity of the power
connection cables, and avoid ground loops (i.e.
avoid connecting one field device to several
controllers).

Wall Modules
The T7460 and T7560 Wall Modules can be used in con-
junction with the W7754 to perform room temperature
sensing, set-point adjustment, fan speed manual override,
and occupancy override. When hardwired to the controller (via
terminals 4, 5, 6, 9, and 10), the wall module's LED/LCD can
be configured to provide information about

any override of the controller by, e.g., manual operation of
the wall module or the receipt by the controller of a net-
work command (see section "Configuration of LED to
Display Info on Overrides" below);

the controller's effective occupancy mode (see sections
"Configuration of LED to Display Info on Occupancy
Mode" and "Configuration of LCD to Display Info on
Occupancy Mode" below).
NOTE: The left DIP switch located on the top of the con-
troller (see Fig. 1 on page 1) is used to indicate that
a wall module can be hardwired to the controller.
Setting the left DIP switch to USED means that a
wall module can be hardwired; setting it to UNUSED
means that no wall module can be hardwired. Use
only an appropriate tool (e.g., ball-point pen) to set
the DIP switch.
NOTE: The intended use of the wall module's buttons must
be configured using Honeywell's LNS plug-in.

Example:
The T7560A has a left button configurable as a fan speed
button, a middle button configurable as a unit ON/OFF button,
and a right button for override. See T7460 Wall Modules
Installation Instructions (95-7610) and T7560 Digital Wall
Module Installation Instructions (EN1B-0146GE51) for details.
