Water Temperature Control - Recirculation Systems Digital The Brain® Model DMC40BS DMC40BS is a fully Digital Mixing Center (DMC), with BrainScan® - hot water monitoring control module, 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).

Operational Specifications (DRV40)

• +/-2°F water temperature control at points of use 25’ downstream during demand

• +/-2°F water temperature control at the DRV during zero system demand “idling” periods

• 2°F minimum valve inlet to outlet temperature requirement

(system recirculation temperature loss)

• Automatic shutoff of hot water flow upon cold water inlet supply failure

• Automatic shutoff of hot water flow in the event of a power failure

• Programmable set point range of 81-158°F (27-70°C)

• Programmable thermal disinfection mode

• Programmable 1st level hi/lo temp alarm display

• Programmable temperature error level for safety shutdown

Technical Specifications (DRV40)

• 100-240 V AC

• Polymer Electronics Enclosure

• Stainless Steel Valve Construction

• Complete Assembly Lead Free Compliant

• Maximum inlet HW supply temperature 185°F (85°C)

• Minimum Circulation Flow – 5 GPM/19 LPM

• Minimum System Draw Off - 0

• ASSE 1017, CSA B125 and CE Certified

• Operational water pressure of 10-150 psig

• Display in °C or °F

• Shipping weight 334 lbs (151.5 kg)

Connectivity (DRV40) SPCO Relay Outputs – Relay which is energized during operation.

LCD Display – Provides information on set point, delivered temperature, error codes and alert conditions.

RS485 Serial Port – Connects the DRV to either BrainScan or Modbus.

BrainScan® – BAS interface for Modbus, Bacnet™ or LonWorks™ plus operates as a web server.

Modbus – DRV can be configured to communicate directly with Building Automation Systems (BAS) using Modbus protocols.
