Honeywell JADE™ Logic/Controller Module W7220A

FEATURES

The JADE™ Economizer System is an expandable economizer control system, which includes a W7220 Economizer Module (controller) with an LCD and keypad. The W7220 can be configured with optional sensors.

The W7220 Economizer Module 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.

The W7220 Economizer Module can be connected to optional Sylk Bus (S-Bus) sensors for Single or Comparative (Differential/Dual) Enthalpy control. The W7220 Economizer Module provides power and communications on the S-Bus for the Sylk Bus sensors.

The W7220 Economizer Module automatically detects sensors by polling to determine which sensors are present. If a sensor loses communications after it has been detected, the W7220 Economizer Module indicates a device fail error on its LCD.
