3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
5. When adding a CO2 sensor (DCV sensor) in the field,
the MIN POS and DCV MAX position potentiometers
must be adjusted by the installer. The MIN POS potenti-
ometer must be closer to the fully CCW position that the
DCV MAX potentiometer for the damper to modulate
beteen the two settings on a call for DCV.

Location and Mounting

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. 1 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, see Fig. 3.
CAUTION
Equipment Damage Hazard.
Mounting screws longer than 5/8 in. can damage
internal motor components.
When mounting the module to an M7215 use only the
included #6 5/8 in. thread-forming screw.
NOTE: See Fig. 4 for representative locations of connected
system devices.
