Quest Controls Inc. has introduced the Model 600 Controller, a low-cost HVAC automation solution for critical facilities. The Model 600 is designed to work as a standalone HVAC control system or work in conjunction with Quest’s TELSEC ESB2 Environmental Controller to provide a comprehensive monitoring and control system for Telecom/Broadband facilities. The Model 600 has the flexibility to handle wall packs, rooftops and split systems plus support for single, dual stage systems and heat pumps. Multiple HVAC units can be grouped by the area they serve to provide lead/lag/standby functionality per zone. HVAC systems with economizers can take advantage of Quest’s patented economizer control algorithm to maximize the amount of time outside air can be used to maintain the temperature in each zone.
