TC Thermostats
Zone Damper Control
What is a Pelican zone damper controller?
A zone damper controller is a Pelican thermostat, and
its accessories, that controls a zone's temperature by
adjusting one or multiple zone damper actuators and
reheats. These dampers either provide or restrict
airflow into that space.
This installation manual explains how to wire
and configure a Pelican thermostat, and other
thermostat accessories, as a zone damper
controller. Pelican thermostats can control a
variety of different type of mechanical
systems. For applications outside of this install
manual, please reach out to the Pelican
engineering support team for further
assistance.
How does the zoning solution work?
A zone thermostats is one device in Pelican's zoning
solution. Thermostats get installed to control individual
zone dampers and/or reheat positions. And in some
situations require accessories to provide complete
damper operation. A Pelican zone coordinator gets
installed to control one or more central air handlers
which provide heating, cooling, and ventilation to these
thermostat's zones.
The zone thermostats establish communication with its
zone coordinator over Pelicans wireless mesh network.
Thermostats send real-time heating, cooling, and
ventilation requests to the zone coordinator, which
processes these requests and make adjustments to the
central equipment to satisfy the different zone
demands.

Installation Manual
Zone thermostats adjust their dampers and reheats in
anticipation of the available cycle. 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 each zone
thermostat will control its zone damper and reheats. It
also sets which sequences and targets are active. For
more information on standard zone thermostat
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
controllers to operate while the Internet
connection is unavailable.
IMPORTANT
A Pelican zone coordinator MUST be installed and wired
to control the central HVAC equipment for a Pelican
zoning solution to work. The zone coordinator releases
zone thermostats to be configured as zone damper and
reheat controllers.
If the following items cannot be wired and controlled by
the zone thermostat, stop the installation immediately
and contact Pelican engineering support for further
assistance:
1) Each zone thermostat MUST control when
its damper is open and closed.
2) Zone dampers MUST be able to rotate to
their 100% open and 100% closed
position.
3) If available, zone thermostats MUST
control when their reheat is open/closed
