Location and Mounting W7459 
Economizer Logic Module 
Mount the W7459 Economizer Logic Module on the side of 
the M7415 or M8405 Damper Actuator. When planning the 
installation, allow enough clearance for maintenance and 
service. Install the W7459 Economizer Logic Module where it 
is protected from rain and snow. One mounting screw is 
supplied to secure the W7459 to the actuator (after the 
actuator is mounted). See Fig. 14.
Location and Mounting W7212
The logic modules mount on an M7215 or a sheet metal duct 
or panel. When planning the installation, allow enough 
clearance for maintenance and service (see Fig. 15 and Fig. 
16 for dimensions). Mount device in a location protected from 
rain, snow and direct sunlight. Secure device to sheet metal 
using the two supplied mounting screws.
