Quest Controls has enhanced its Model 600 Lead/Lag HVAC Controller with built-in Ethernet connectivity. The upgrade delivers advanced remote access, monitoring, and configuration capabilities. Users can monitor and adjust system settings remotely via a password-protected web interface or Modbus TCP, reducing the need for on-site service calls and enabling smarter environmental control from anywhere.
Model 600 can control two independent HVAC units, providing robust lead/lag operation and redundancy for critical sites. For larger or more complex deployments, multiple Model 600 controllers can be networked together and integrated with Quest Controls’ flexible architecture for centralized management.
