Honeywell Excel 10 Installation Instructions

BEFORE INSTALLATION
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.
