Siemens RTU Solution Simplifies
Efficiency for Small to Mid-size
Buildings
Siemens has unveiled its Climatix® Rooftop Unit (RTU)
optimization solution, designed for millions of smaller to medium-size
buildings such as small offices, retail, grocery and
convenience stores, restaurants, K-12 facilities, and houses of
worship. This market relies mostly on basic thermostat control
for heating and cooling and faces increasing pressures to
reduce costs. The controller-driven solution addresses a gap
in the market to improve energy efficiency, indoor air quality
(including fresh air intake circulation), and overall building
comfort — without having to add a complete building
automation solution. It also includes remote management
service that allows HVAC mechanical and controls contractors
to gain real-time access to RTU performance data through
the Internet, saving time and money by eliminating system
downtime and unnecessary truck rolls.
“We set out to deliver a better rooftop unit management
solution unlike any other that’s designed with efficiency
in mind for both contractors and building owners,” stated
John Karczmarczyk, Vice President, Siemens Smart Infrastructure
USA. “This new solution has been tested and deployed
working closely with our channel partners, to provide a true
turnkey solution at an affordable price.”
RTUs have an average product lifespan of 15 to 25 years,
with 90 percent of them continually running at a single fan
speed regardless of need, creating inefficiencies. Without
proper maintenance, equipment performance can decline
over time, leading to poor indoor air quality, poor temperature
management, nuisance noise, increased energy bills and
unexpected system downtime with more costly repairs.
The Climatix RTU solution is designed for plug-and-play
installation, with pre-terminated inputs and outputs reducing
labor costs for contractors. The Climatix RT controller is
pre-engineered with pre-defined applications designed specifically
for RTUs and paired with Siemens sensors, the new
Climatix VFD, and OpenAir® actuators to optimize installation,
commissioning, and performance. The Climatix VFD has
its sequence of operations specially programmed into the
Climatix RT controller which helps contractors save hundreds
of hours in training and commissioning.
During this pandemic time when indoor air quality and
proper ventilation is critical, this new solution helps building
owners address these concerns maximizing fresh outdoor air
to the fullest extent possible, with three applications tailored
to optimize indoor air quality and energy efficiency.
Climatix IC® remote management software works with the
Climatix RT controller and the Climatix mobile app for RTU
configuration, commissioning, and operations. The mobile
app allows for secure monitoring, alarming, troubleshooting
and program updates of equipment installed at multiple
locations. Set points and schedules can also be adjusted
remotely.
Remote connectivity makes commissioning new RTUs faster
and easier — even by junior technicians or apprentices working
on their own. Remote monitoring also makes it easier
to identify and troubleshoot potential system issues before
dispatching service technicians onsite.
