Direct VAV Control from the J-Series Thermostat & Delta Controls Red5 Edge-v100
The NetX J-Series Thermostat now integrates directly with the Delta Controls Red5 Edge-v100 VAV Controller, giving technicians and building owners straightforward control of VAV systems right at the thermostat. No VAV box replacement. No mandatory BAS. No added complexity.
In Partnership With 
BAS When You Want It – Not When You Don’t
No Building Automation System is required. But, when integration is needed, NetX connects seamlessly via BACnet or Modbus, allowing smooth coexistence with larger BAS environments—on your terms.
- New J-Series: Wi-Fi or Ethernet (BACnet/IP & ModbusTCP/IP Included)
- Simultaneous Triple-Connection:
- VAV Box Controller
- BACnet or Modbus over Wi-Fi or Ethernet
- Client NetX Cloud Connection
- Flexible Configuration: Complete Setup of VAV Parameters Directly from the Thermostat Touchscreen
Eliminates Complexity
Traditional VAV systems often force you into full BAS deployments, which are expensive, time-consuming, and overkill for many buildings. NetX delivers VAV functionality without the layers of programming, licensing, and commissioning overhead.
Designed for Real-World Retrofits
Keep existing VAV boxes in place. Add intelligent control at the zone level without ripping out infrastructure or retraining operators on a full BAS platform.
Simultaneous Triple-Connection
The J-Series thermostat maintains connectivity with the VAV Box Controller, BACnet or Modbus over Wi-Fi or Ethernet, and Client NetX-Cloud. Control dampers, airflow, and zone behavior directly from a clean, intuitive thermostat screen or through any device browser, without requiring proprietary tools or specialized BAS technicians.
The Missing Middle Ground
Residential smart thermostats aren’t capable enough for VAV systems. Full BAS solutions are often too costly and complex. NetX bridges the gap—professional-grade control that’s powerful, practical, and easy to deploy.
Collaborative Technology from Industry Leaders
This solution is a collaboration between NetX and Delta Controls. Together, these companies are enabling smarter building ecosystems through open, interoperable technologies, powered by the J-Series Thermostat from NetX.
