Armstrong The Brain® DMC Series Digital Mixing Center (DMC), equipped with the SAGE® hot water system monitoring and reporting tool, is designed specifically to be the primary water temperature controller in a continuously pumped circulating hot water system. Digital technology provides enhanced water temperature control accuracy which resists zero system demand "Temperature Creep" without the use of a manual throttling valve or a temperature activated pump shut-off device (aquastat).

Connectivity and SAGE® Integration

SAGE® (BS) is available with specific ProtoCessor cards for Building Automation System (BAS) connectivity to systems which operate on Modbus TCP, BACnet™, or LonWorks™ protocols. Mobile connectivity features smart hot water system dashboard monitoring, secure remote programming, multi-location view, temperature and system diagnostic alerts, with unlimited digital documentation and automated report generation. Mobile connectivity may be enabled by a customer activated subscription.

Operational Specifications

• Temperature Control: +/-2°F DRV water temperature control at peak, moderate or zero fixture demand on hot water systems designed for continuous recirculation.
• Temperature Differential: 1°F minimum recirculating water temperature differential.
