SEZ7000 BACnet Commercial Zoning System Features
Introduction
The SEZ7000 BACnet® commercial zoning system is specifically
designed to bring a simple scalable BACnet zoning system solution to the
commercial mid-market without the cost associated with a typical DDC
zoning system.
Our zoning system provides even more flexibility by offering additional
functionality and new models covering more applications while still
achieving excellent energy savings. The new central models include
rooftop and heat pump units controlling analogue heat, CO
and indoor air quality in conjunction with zoning controllers that provide
floating and analogue damper control. The most unique feature of the
zoning system is its scalability; a single central controller unit can support
up to 63 individual zone controllers.
Zoning System
All zone controllers can be ordered with an on-board passive infrared
(PIR) occupancy sensor cover that allows for advanced occupancy
AT A GLANCE
Custom design
• Best in class system scalability
• Provides DDC type control functionality and
accuracy
• No external software tools required for
installation, commissioning or servicing with
embedded local HMI utility
• ZigBee® communication protocol
• Full line of models offer solutions for a wide
range of application
• Control IAQ with any typical third-party wall
mounted C02 sensor
• Controls and measures fresh air with any
third-party fresh air measurement station
• Provides embedded free cooling economizer
loop
• Built in Network-ready functionality
Options and accessories
• PIR occupancy sensor
strategies. This enables the zone controllers to be able to provide even
greater energy savings to zones during scheduled occupied events when
no occupants are present. This automatic energy-saving feature reduces
overall operating costs and accelerates return on investment.
With exceptional system performance rivalling more costly and complex
programmable automation systems, the SEZ7000 can be installed at a
fraction of the total cost of a comparable system. System installation,
setup, and commissioning have been simplified by eliminating the need
for additional external commissioning equipment or tools. All required
testing and configuration including addressing and zone-weighting is
accomplished using the easy-to-read LCD interface provided on
all controllers.
Moreover, since no other programming tools are required, mechanical
service technicians can quickly and easily install and service the system
without costly support.
The SEZ7000 offers unparalleled flexibility through the use of the open
BACnet communication protocol. The system can also be complemented
with your choice of BACnet controllers or graphical workstation software.
BACnet object mapping can also be accomplished seamlessly without the
need for any complex programming tools.

SEZ7000 BACnet Commercial Zoning System
By installing the zoning system in your building, energy required to render the space comfortable will be used more efficiently
when compared to buildings using conventional control systems. Operating costs will be reduced and an overall healthier work
and living environment will be achieved.
With LEED certification becoming more prevalent in today’s new and existing commercial buildings, the BACnet zoning system
now offers the added advantage of bringing your building one step closer to attaining the credits required for LEED certification.
The BACnet zoning system can help in attaining indoor environmental quality credits when used in conjunction with CO2 sensors
and a fresh air measurement device. The IAQ controller can monitor indoor air quality, provide C02 demand-based ventilation,
and fresh air measurement and control. It also offers embedded free cooling economiser control, ensuring that cooling energy
efficiency is optimised.
When used with central scheduling functions, the optional PIR motion sensor with occupancy logic based on actual occupancy
detection can also help attain HVAC energy-efficiency LEED credits.
The zoning system allows building owners to maintain a healthy environment for their occupants as well as maximise the overall
environmental and economic performance of
their buildings.
