Honeywell W7220A1000

• 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 for 4 different economizer strategies: referential or differential dry bulb, referential or differential enthalpy
• The W7220 economizer module can be used as a standalone economizer module wired directly to a commercial setback space thermostat and sensors to provide outdoor air dry bulb economizer control
• The W7220 economizer module can be connected to optional Sylk bus sensors for single or differential enthalpy control
• The W7220 economizer module provides power and communications on the Sylk 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 indicates a device fail error on the display or through the aux 1 out terminal programmed to SYS
• 5 to 95% RH non-condensing operating humidity range
