Pelican Z24 Installation Manual

What is the zone coordinator?
The zone coordinator is a field-installed equipment
controller. For most applications, it controls the central
equipment that provides heating, cooling, and
ventilation to multiple zones or spaces.
This installation manual explains how to use a
zone coordinator as a multi-zone HVAC
equipment controller. This controller can also
operate a variety of other centralized
equipment such as, but not limited to, exhaust
fans, make-up air units, 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 Pelican's zoning
solution. It is installed as the central air handler
controller, while 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 processes these requests
and makes adjustments to the central equipment to
satisfy 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
connection 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 "Sequence of Operations" on page 40.
The Pelican zoning solution and its related
devices require an Internet connection¹ for
initial device configurations. After
configurations are set, the Internet
connection provides virtual climate
management, data logging, equipment fault
notifications, configuration adjustments, and
other energy management features. These
features are important to verify the 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 further 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 cannot be wired and
controlled by the zone coordinator, stop the
installation immediately and contact
Pelican engineering support for further
assistance:
1) The zone coordinator must control when
the equipment's supply/return fan(s) are
active. These fans must be able to run
