APPLICATION
W6215, W7215, and W7460 Economizer Logic Modules are
used with an indoor sensor input (ISI), and solid state C7400
Enthalpy Sensors or C7650 Dry Bulb Temperature Sensors.
All models proportion outdoor and return air dampers for
control of free cooling in commercial HVAC equipment. The
W7215B and W7460B are used with an outdoor sensor input
(OSI) along with the ISI.

W6215, W7215, W7460
Economizer Logic Modules
FOR VENTILATION CONTROL
FEATURES
• Operates from the space thermostat and an ISI to
provide a totally integrated control system.
• Solid state control package provides accuracy,
reliability and stability.
• Housed in high-impact, glass-fiber reinforced
plastic case.
• Mounts on sheet metal duct or remotely in a
mechanical room. Mounting screws included.
• The W6215 and W7215 are used with Honeywell
Series 62 and Series 72 actuators (respectively).
The W7460 is used with Honeywell M7415 Damper
Actuators.
• Combines minimum and maximum damper position
potentiometers and compressor staging relay
functions with solid state enthalpy or dry bulb
changeover control this control can be tempered
by ISI, and fan cycling.
• Outdoor Sensor input incorporated into logic of
W7215B and W7460B models.
• Shutdown and Air Change can be used with all
models.
• Purge cycling can be used with the W6215A, W7215A
and W7460A models.
• Terminals included for connecting optional S963B1128
Remote Potentiometers for remote minimum and
maximum damper position control.
• LED and relay terminals indicate when free cooling
is available.
• LED indicates when module is in ISI mode.
