The W7220 Economizer Module is the core of the JADE™ system and provides the basic inputs and outputs to provide simple economizer control. When used with the optional Sylk Bus sensors, the Economizer Module provides more advanced economizer functionality.

• W7220 can be used as a standalone economizer module wired directly to a commercial set back space thermostat and sensors to provide Outdoor Air dry-bulb economizer control.
• W7220 automatically detects sensors by polling the Sylk Bus to determine which sensors are present. If a sensor loses communications after it has been detected, the W7220 Economizer indicates a device fail error on its LCD.
• The module is designed for use with any Honeywell 2 to 10 Vdc or Honeywell Sylkbus communicating actuator.
• Use with sensors: dry bulb temperature and mixed air, C7250A; temperature and humidity, C7400S1000 (optional); DCV (CO) sensor (C7232); humidity, C7600 (optional)
  Y7220A7215 includes the W7220A1000 logic module, (2) C7250A1001 sensors for outside and mixed air dry bulb applications, and M7215A1008 25 lb-in, foot mount, spring returnactuator motor
