AERCO's Benchmark Platinum Boiler with Edge Controller
Delivers Maximum Efficiency and Performance

ow featuring the advanced Edge™ Controller, AERCO's
Benchmark® Platinum condensing boiler saves time and
money on install and operating costs, simplifies start-ups and
maintenance, and strengthens system performance. Through
patented technology and innovative features, Benchmark
optimizes hydronic systems delivering up to 9% additional
efficiency, resulting in the lowest cost of ownership.
In an ideal world, high efficiency commercial boilers would
operate as designed - condensing as you expect and delivering the highest efficiency possible. However, in the real world,
external variables cause faults that lead to system inefficiency,
increased utility costs and unit downtime. AERCO's Benchmark Platinum optimizes your system for the real world by selfcorrecting these problems so you'll reduce costly unscheduled
maintenance and receive greater energy savings.

Edge™ Controller and Mobile App
With advanced features such as EZ Setup and Combustion
Calibration Assist, the Edge Controller makes it even easier
to install, service and maintain the Benchmark boiler for peak
performance and maximum savings. Edge mobile app enables
full unit setup and control with enhanced diagnostics and capabilities with the flexibility and freedom to move around the
unit when configuring, diagnosing and troubleshooting. App
is available on iOS and Android.

AERtrim
Advanced combustion control systems in condensing boilers
need to maintain precise air/fuel ratios in order to work properly
and maximize efficiency. However, environmental variations
(such as humidity, atmospheric pressure, filter dust loading,
delivered gas energy content and other factors) can often wreak
havoc causing boilers to deviate from the ideal oxygen-fuel
ratio. AERtrim, AERCO's patented O2 Trim technology, monitors actual site conditions and self-adjusts its combustion process to ensure the boiler is operating at optimal O2 levels for
peak system efficiency. Proper O2 levels provide greater uptime
reliability, increased energy savings, fewer emissions, lower
operational and maintenance costs, as well as an additional
1%-2% seasonal efficiency gain.

Dual Returns
Benchmark Platinum's Dual Returns allow engineers to
design the most efficient system possible. Most traditional
boilers offer a single return that forces the blending of hot
and cold water. However, Benchmark Platinum's Dual Returns
keep cold water separate, creating a larger condensing zone
in the heat exchanger that improves boiler efficiency up to
7%. Dual Returns are ideal for applications that feature combination systems including multi-zone space heating, space
heating with domestic hot water, radiant floor heating, snow
melt, and pool heating, or as the system's by-pass to the high
temperature connection.

onAER Predictive Maintenance
onAER Predictive Maintenance continuously monitors the
overall health of the system helping customers properly maintain and protect their investment. onAER provides a convenient
site that offers an intuitive overview of the system including unit
performance, plant efficiency, upcoming maintenance required,
technical data and more. onAER allows for quick resolution
of issues and prevents more serious problems from developing
that can result in inefficient operation and increased expenses.
Monthly reports and instant email alerts notify customers and
facility managers of any faults or decline in equipment to prevent unnecessary wear-and-tear as well as premature failure.
With its combination of innovative technologies and features, Benchmark Platinum optimizes system performance and
provides maximum efficiency for bigger savings and greater
Return on Investment.
