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

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.
