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. 12.

C7400 Enthalpy Sensor and C7650 A
Temperature Sensor
Location and Mounting
Outdoor air sensing: Mount the C7400 Enthalpy Sensor or
C7650A Temperature Sensor in any orientation where it is
exposed to freely circulating air but protected from rain, snow
and direct sunlight.
Return air sensing: For differential enthalpy or temperature
control, a second C7400 Enthalpy Sensor or C7650A
Temperature Sensor is connected to the W7459. Mount the
second sensor in the return air duct as far as possible from
the outdoor air sensor.
Wiring
CAUTION
CAN CAUSE ELECTRICAL SHOCK OR
EQUIPMENT DAMAGE.
Disconnect power supply before connecting wiring.
Disconnect the power supply before connecting wiring to
prevent electrical shock or equipment damage. All wiring
must comply with applicable local codes, ordinances and
regulations. See Fig. 13 for a typical wiring diagram.
