Recirculating Valve (DRV) can be used to connect the DRV to
eitherBrainScan®ordirectlytoaBuildingAutomationSystem
(BAS)whichoperatesonaModbusprotocol.
BrainScan®
BrainScan® is an optionally selected control module from
ArmstrongwhichenablesaninterfacewithBuildingAutomation
Systems(BAS)whichutilizeModbus,Bacnet™orLonWorks™
protocols via the use of specific protocessor cards.
BrainScan® also has an ethernet port and operates as a web
server for remote network access.
BrainScan® includes remote hot water supply, cold/ recirculation
water supply, blended water outlet temperature outputs and is
supplied with a system graphic, memory card for data storage
and web based software.
BrainScan® includes terminals for additional installer supplied
RTD’s, pressure transducers and pulse type flow meters and

Modbus
Modbus – DRV can be configured to communicate directly with
BASwhichuseModbusprotocols.
When configured for Modbus the DRV becomes a Remote
Terminal Unit (RTU).
