W7212, W7213, W7214
Economizer Logic Modules
FOR VENTILATION CONTROL
APPLICATION
W7212, W7213, and W7214 Economizer Logic Modules are
used with C7232 (CO2) Demand Control Ventilation (DCV)
Sensors, and solid state C7400 Enthalpy Sensors or C7660
Dry Bulb Temperature Sensors. All models proportion outdoor
and return air dampers for control of free cooling in
commercial HVAC equipment.

FEATURES

• Operates from thermostat and DCV (CO2) sensor to
provide a totally integrated control system.
• Solid state control package provides accurate, reliable
and stable control.
• Mounts on M7215 Motor or ductwork.
• Control can be tempered by DCV and fan cycling.
• Used with Honeywell actuators.
• Combines minimum and DCV maximum damper
position potentiometers with compressor staging.
• Solid state enthalpy or dry bulb changeover control.
• Terminals included for switching between Occupied
and Unoccupied operation.
• Terminals included for connecting optional S963B1128
Remote Potentiometer for remote minimum damper
position control.
• LED indicates when free cooling is available.
• LED indicates when module is in DCV mode.
• LED indicates when exhaust fan contact is closed.
• On CO2 sensor failure defaults to DCV maximum
damper position for minimum position.
This feature was added with the series 2 version of the
product. See Table 1.
• W7213 is used with heat pump B terminal.
• W7214 is used with heat pump O terminal.
• W7212C is used for applications requiring low
temperature and humidity and has the "E" enthalpy
curve.
