Honeywell W7220A1000 Module

The Honeywell W7220A1000 is the core JADE Economizer Logic Module designed for high-efficiency rooftop units and air handling systems. As a veteran-grade HVAC economizer controller, this unit supports Demand Control Ventilation (DCV) and provides a 2-10 Vdc output to drive Series 72 actuators or Sylk Bus communicating actuators. It features an integrated LCD screen and keypad for streamlined field commissioning, allowing technicians to configure four distinct strategies: referential or differential dry bulb, and referential or differential enthalpy. This 24 Vac module automatically detects Sylk Bus sensors like the C7400S1000 for precise enthalpy control and the C7250A for mixed air sensing. Built to comply with California Title 24 and ASHRAE equipment standards, the Honeywell JADE W7220 includes robust onboard fault detection and diagnostics (FDD). This ensures your mixed air temperature and outdoor air intake are optimized for energy savings and indoor air quality without the complexity of legacy analog setups.

Key Benefits:

• Advanced DCV Integration: Supports 2-10 Vdc CO2 sensors to modulate fresh air intake based on occupancy.
• Simplified Commissioning: Built-in LCD interface eliminates the need for external tools for standard economizer setup.
• Sylk Bus Communication: Two-wire, polarity-insensitive technology reduces wiring errors and enables automatic sensor polling.
• Regulatory Compliance: Meets Title 24, IECC, and ASHRAE 90.1 requirements for fault detection and diagnostics.
• Operational Reliability: Durable gray housing rated for temperatures from -40°F to 150°F (-40°C to 65°C).

Common Questions:

How do I configure the Honeywell W7220A1000 for enthalpy changeover?
To enable enthalpy logic, you must connect a Honeywell C7400S1000 enthalpy sensor to the Sylk Bus. The JADE module will automatically detect the sensor and allow you to select referential or differential enthalpy strategies via the onboard menu.

Can the JADE W7220 replace older W7212 or W7459 modules?
Yes, the Honeywell W7220A1000 is the modern digital replacement for legacy W7212, W7214, and W7459 series logic modules, though it requires compatible 20k ohm NTC or Sylk Bus sensors and 2-10 Vdc actuators.

What does the 'SYS' alarm on the JADE display indicate?
A 'SYS' alarm typically points to a communication failure with a previously detected sensor or a fault in the system configuration. Technicians can use the diagnostic menu to identify the specific failed component.
