Why the JADE W7220 Exists
A high number of economizers in the field were found to be:
- Inoperative
- Improperly configured
- Disconnected
- Failing to provide the expected energy savings
New national, state, and local standards now require verified performance and fault detection. The JADE W7220 was designed specifically to meet these requirements and eliminate guesswork.
Supported Codes and Standards
The JADE W7220 helps meet key industry codes, including:
- ASHRAE 90.1 – Energy efficiency requirements
- ASHRAE 62.1 – Ventilation & indoor air quality
- ASHRAE 189.1 – High-performance green buildings
- IECC 2006 & 2011 – Energy conservation
- IGCC – Green construction guidelines
These standards demand accurate ventilation control, diagnostics, and energy-conscious operation. The W7220 delivers on all three.
