Honeywell Excel 5000 Open System Installation Instructions

BEFORE INSTALLATION
The Excel 10 Hydronic Controller is available in the following
two models:
1. W7762A—with integral setpoint adjustment.
2. W7762B—no integral setpoint adjustment.
The models all have similar housings and mounting
procedures.
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
W7762 Hydronic 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.
