CONTROLLERS
INSTALLATION INSTRUCTIONS
The Excel 10 Chilled Ceiling Controller is available in the
following three models:
1. W7763C—with integral setpoint adjustment,
temperature sensor, and bypass push-button.
2. W7763D—with integral setpoint adjustment only.
3. W7763E—no integral setpoint adjustment, sensor, or
push-button.
The models all have similar housings and mounting pro-
cedures.
IMPORTANT
It is recommended that devices be kept at room
temperature for at least 24 hours before applying
power to allow any condensation resulting from low
shipping/storage temperatures to evaporate.
INSTALLATION
W7763 Chilled Ceiling Controllers can be mounted on a
panel or wall or onto a standard 60-mm wall outlet box using
No. 6 (3.5-mm) screws. See Fig. 1 for outside dimensions
and Fig. 2 for subbase mounting dimensions.
The controller can be mounted in any orientation desired;
however, for thermal reasons, W7763C Controllers must not
be mounted on a ceiling.
Wiring
All wiring must comply with applicable electrical codes and
ordinances. Refer to job or manufacturers’ drawings for
details.
Power
Input power provided must be 24 Vac (±20%), 50 or 60 Hz.
For US installation, power must come from an energy-limited
Class II Power Source (transformers must not exceed
100 VA). More than one W7763 Controller can be powered
by a single transformer.
CAUTION
Turn off power prior to connecting to or removing con-
nections from any terminals to avoid electrical shock
or equipment damage.
Use the heaviest gauge wire available, up to 14 AWG
(2.5 mm2)with a minimum of 18 AWG (1.0 mm2) for all power
wiring.

IMPORTANT (US only)
If the W7763 Controller is used on UL 1995 Heating
and Cooling Equipment and the transformer
primary power is more than 150 Vac, connect the
transformer’s secondary to earth ground. For these
applications, only one Excel 10 controller can be
powered by each transformer.
Communications
Wire the controller's LONWORKS® network using level IV 22
AWG (Belden part number 9D220150) or plenum-rated level
IV 22 AWG (Belden part number 9H2201504) nonshielded,
twisted pair, solid conductor wire. When possible, use
Honeywell AK3781, AK3782, AK3791, or AK3792 cable (US
part numbers). See E-Bus (LONWORKS® network) Wiring
Practices, form number 74-2865, for more information
including maximum lengths.
Pull the cable to each controller on the LONWORKS® network
and connect to terminals 19 and 20.
The W7763 Chilled Ceiling Controller utilizes a free topology
transceiver (FTT10A) Link Power compatible LONWORKS®
network that allows daisy-chain, loop, and star network con-
figurations or any combination thereof. Depending upon the
LONWORKS® network configuration used, one or two ter-
mination modules, part number 209541B, may be required.
Different connections to the termination module are
necessary, depending upon whether it is used in a singly- or
doubly-terminated network configuration. See Excel 10
FTT/LPT 209541B Termination Module Installation
Instructions, form 95-7554.
NOTES:
— The LONWORKS® network is insensitive to polarity,
eliminating installation errors due to miswiring.
— Do not bundle output wires with sensor, digital input or
communications bus wires. Maintain a minimum 3 in.
(76 mm) separation between LONWORKS® network and
Triac output and power supply wiring.
— During installations, try to avoid areas of high electro-
magnetic noise (EMI).
— Chilled Ceiling Controllers have a 3.5-mm LONWORKS®
network jack for easy network access.
— For more information see E-Bus (LONWORKS® network)
Wiring Guidelines, form number 74-2865.
Wall Modules
A variety of Excel 10 wall modules can be used with W7763
Chilled Ceiling Controllers. See T7460 Wall Modules In-
stallation Instructions, form number 95-7610; T7560 Digital
Wall Module Installation Instructions, form number 95-7620;
and T7770 Wall Modules Installation Instructions, form
number 95-7538 for installation details.
NOTE: Wall Modules with fan speed switches must not be
used with W7763 Chilled Ceiling Controllers.

Wiring Details
Connections to the Chilled Ceiling controllers are made at
two internal terminal blocks accessible beneath the front
cover. No tools are required to remove the front cover.
Simply pull away from the subbase as shown in Fig. 4.
Fig. 4. Terminal cover removal.
Fig. 5. Mounting on wall outlet box.
Use a minimum wire size of 20 AWG (0.5 mm2) for all input /
output connections. The maximum length of all input / output
cables and wall module interface cables is 65 ft (20 m). Main-
tain 3 in. (76 mm) minimum spacing between signal lines 1-
10 and Triac output and power supply wiring.
Fig. 8 illustrates the terminal assignments of the controllers.
Table 1 lists Triac output assignments for various actuator
types. Refer to job drawings for specific wiring diagrams.
IMPORTANT
Screw type terminal blocks are designed to accept
no more than one 14 AWG (2.5 mm2) conductor.
Multiple wires that are 14 AWG (2.5 mm2) can be
connected with a wire nut. Include a pigtail with this
wire group and attach the pigtail to the individual
terminal block.
Wire to the terminal blocks as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. Insert the wire in the required terminal location and
tighten the screw to complete the termination. Insure
that the wire entering the terminal block does not ex-
tend above the numbered face of the terminal block to
avoid contact between the wires and the printed circuit
board on the underside of the front cover (see Fig. 6.)
Fig. 6. Terminal block connections.
IMPORTANT
When two or more wires are to be attached to the
same terminal, be sure to twist them together.
Deviations from this rule can result in improper
electrical contact. See Fig. 7. Local wiring codes
may take precedence over this recommendation.
