Pelican thermostats and accessories can be wired and
configured to control a wide range of zone dampers.
Refer to the “ Intallation Planning” diagrams on pages 6
to 12 for the most common applications.
It is essential to follow these diagrams, as the
controller’s outputs are closely linked to their
configured functions. Verify proper mechanical
operation before and after installation and ensure that
all configurations are accurate for your installation.
For installations outside of these diagrams, stop what
you are doing and contact Pelican support for further
assistance.

The zone thermostat sends 24V AC from [Y] to power
the damper open for heating, cooling, and ventilation
cycles. When 24V AC is removed, the dampers’ actuator
springs closed.
Note: As shown in the diagram, install a discharge air
sensor to ensure proper damper operation. Refer to
page 16 for detailed wiring diagrams of accessory.
