Pelican Z24 Installation Manual

What is the zone coordinator?
The zone coordinator is a field installed equipment
controller. In most applications, it manages the
operation of central equipment providing heating,
cooling, and ventilation to multiple zones or spaces.
Each zone would have its own zone damper which is
opened and closed by a local Pelican thermostat to
allow conditioned air into its area of a building.
This installation manual goes over how to use
a zone coordinator as a multi-zone HVAC
equipment controller. This controller can also
be used to operate a variety of other
centralized equipment such as, but not limited
too: exhaust fans, make-up airs, boilers,
cooling towers, chillers, etc. For applications
outside the scope of this installation manual,
please contact Pelican engineering or technical
support for further guidance.
How the Pelican zoning solution works
The zone coordinator is one device in a Pelican's zoning
solution. The zone coordinator is installed as the central
air handler controller, while multiple Pelican
thermostats are installed to control individual zone
dampers and/or reheat positions. The zone coordinator
establishes communication with each of its zone
thermostats over Pelican's wireless mesh network.
Thermostats send real-time heating, cooling, and
ventilation requests to the zone coordinator, which then
processes these request and makes adjustments to the

central equipment with the goal of satisfying the
different zone demands. The Pelican zoning solution's
logic is designed to enhance equipment performance,
energy efficiency, and building comfort across the entire
mechanical system.
The wireless mesh network also provides an Internet
connection¹ for these devices to reach the Pelican
Connect app (for more information visit
PelicanWireless.com or contact Pelican support). Zone
coordinators and their associated thermostats are
configured through this web application.
Configurations provide adjustments on how the zone
coordinator will control the central equipment and
which sequences and targets are active. For more
information on standard zone coordinator sequences,
reference page 40.
The Pelican zoning solution and its related
devices require an Internet connection for
initial device configurations. After
configurations are set, the Internet connection
provides virtual climate management, data
logging, equipment fault notifications,
configuration adjustment, and other energy
management features. These features are
important to verify correct operation of the
zoning solution and should be planned as a
retained resource at the end of the
installation. If the Internet is down or lost for a
period of time, all device configurations are
stored locally in each Pelican controller, so all
the equipment and communications will
continue to operate while the Internet
connection is unavailable.
IMPORTANT
The zone coordinator MUST be installed and
wired to control the central HVAC equipment
for a Pelican zoning solution to work. The zone
coordinator provides digital and analog
outputs to adjust and modulate how the
central equipment is operating. These outputs
are futher detailed in later sections of this
installation manual. The zone coordinator also
allows zone thermostats to function as zone
damper controllers. This is detailed in the
Pelican Damper Controller installation
manual.
If the following items are unable to be wired
and controlled by the zone coordinator, STOP
the installation immediatly and contact Pelican
engineering support for further assistance:
1) The zone coordinator MUST control when
the equipment's supply/return fan(s) are
¹Pelican Gateway is required for Ethernet connection.
