Acorn Controls® Command Station® with ET71 Emergency Tempering Valve
The Acorn ConTrols® Command Station® is a self-contained Tempering and Recirculating system. Each system is factory assembled to a welded heavy-duty Mounting Frame for simplified installation. The Command Stations are 100% factory-tested and utilize the ET71 Series Valve (or Valves), which are IAPMO-certified at the published minimum flow, to exceed the performance requirements outlined in the ASSE 1071 standard. Command Stations are designed to reduce the potential for improper piping, missed connections, and/or the omission of key system control components, which are common in contractor "design-as-you-build" installations. The Command Stations have a much smaller footprint and minimize on-site material waste. For any future troubleshooting that may be necessary, a Command Station ensures you have quick, easy access to all critical components required for the process.
