Before you start
Review all instructions before starting to avoid discovering or creating any
issues during installation. This thermostat is designed to be installed on 24
VAC systems only.
This thermostat is designed to be installed by a licensed professional.
A Pelican Gateway must be used with this thermostat. The thermostat cannot
be configured or managed without the gateway. We recommend installing
the gateway prior to installing this product.
Installation location
NEVER INSTALL IN AN ENCLOSED METAL BOX OR ON A METAL SURFACE.
Install in a location where it can communicate with the Pelican wireless mesh
network.
Install 48" to 60" from the floor in the room where it will be maintaining the
temperature.
Install on an interior wall away from doors, filing cabinets, electrical
equipment, or other metal objects.

ON
OFF
Turn off the power to the equipment
this thermostat is going to be wired to.
Either turn off power at the circuit
breaker panel or by turning off the
master power.
Replacing an existing wired thermostat
Remove the cover from the old
thermostat and either take a picture
or label the wires as a guide for wiring
the new Pelican thermostat.
Uninstall the old thermostat and set
aside.
Installing a Pelican thermostat in a new location
This Pelican thermostat is designed to
either mount flush on the wall or on a
vertical 1-gang electrical box.
Choose a mounting location where
the thermostat:
is at least 48" to 60" above the floor.
is on an interior wall.
where it can detect the temperature
of the room it will be maintaining.
and is away from sun exposure or
airflow drafts.

Install the thermostat back plate
Use the included screws to attach the thermostat to the
wall following one of the examples below:
Feed thermostat wire
through opening on back
plate.
Limited Wires? No Common Wire?
Follow pages 4 - 5 for limited wire instructions.
Follow pages 8 – 15 for common
thermostat wiring guides.
Connect wires to thermostat

Use provided machine screws.
Drill two 3/16" holes (if using drywall
anchors).
Install provided drywall
anchors (if required).
Use provided sheet metal screws.
Vertical electrical
box.

Some installations have limited wires
between the thermostat and the HVAC
equipment. The included Wiring
Module can be used to control the
HVAC equipment without having to
run new or additional wires to the
thermostat.
This installation requires at least three
(3) wires between the thermostat and
the Wiring Module (unshielded wire is
okay).
This accommodates a maximum wire
distance of 500 feet between the
Wiring Module and the thermostat.
Step 1: Remove the Wiring Module
from the thermostat’s back plate.
Loosen the (R), (C), and (D) terminals
on the Wiring Module. Gently slide
the Wiring Module upwards (away
from the three pin connector) to
remove.
Step 2: Install the Wiring Module in
the HVAC equipment.
Locate the HVAC equipment’s
control board. Using new wire,
connect the Wiring Module’s
terminals to the corresponding
low-voltage input terminals on the
HVAC control board.
Follow the wiring diagrams from
Pages 8 – 15.

installed to connect the (R), (C), and (D) terminals from the Wiring Module to
the matching (R), (C), and (D) terminals at the thermostat’s back plate.

there are three (3) alignment
pins found on the left and right
sides of the base plate.
Attach the display
Before attaching the display, write
down the serial number on the screen
for use when configuring the
thermostat.
Align the display with the back plate’s
alignment pins. Press into back plate
until it clicks into place.
Switch on the power to the HVAC
equipment the thermostat is wired to.
If your Pelican thermostat does not
power on, see page 16 for assistance.
See page 17 for instructions on setting
the thermostat for Conventional or Heat
Pump control.
Optional: Tamper Resistant Lock
The thermostat contains an internal
locking mechanism to secure the display
to the back plate. This is intended to keep
unauthorized individuals from tampering
with the power and thermostat wire.
To engage the lock, assemble the
thermostat and insert a 1/8" flat head
screwdriver into the hole on the left side
of the thermostat. Push in slightly and
rotate 1/4 turn clockwise until reaching
the stop. Remove the screwdriver from
the hole.
To disengage, insert a 1/8" flat head
screwdriver into the hole on the left side
of the thermostat. Rotate 1/4 turn
counter-clockwise until reaching the stop.
Remove the screwdriver from the hole.
Do NOT force the display from the back
plate otherwise damage may occur.

If the Pelican thermostat does not power on, check the following:
1. Check that all wires are properly inserted into the terminal blocks at the thermostat and
at the HVAC equipment. Lightly pull on the wires to make sure they are not loose.
2. Use a multi-meter to ensure that 24 VAC power is being supplied by HVAC equipment. If
24 VAC is not found, check that the master power has been turned back on for the HVAC
equipment or verify that the HVAC electrical breaker has not tripped. If the breaker has
tripped contact a Licensed Professional to assist, otherwise damage can occur to the
equipment or you can get hurt.
3. Use a multi-meter to ensure that 24 VAC power is found at the thermostat. If 24 VAC
was not found, but is found at the HVAC equipment, check for loose or spliced wires.
3. If you used the Wiring Module, use a multi-meter to ensure that 24 VAC power is found
at the Wiring Module and the thermostat. Check that the (R), (C), and (D) wires are
properly connected between the Wiring Module and the thermostat.
If the thermostat still does not power on, contact Pelican technical support for further
assistance at 888.512.0490.
If the Pelican thermostat does not show up on the Pelican App, check the following:
1. Check the thermostat upper right hand corner.
If you see this symbol then the thermostat is unable to connect to your Pelican
Wireless Mesh Network.
• Finish installing all your other Pelican thermostats and/or devices.
• Verify your Pelican thermostat is not in a metal enclosure and that there are no metal
structures/objects surrounding it. Wireless can NOT communicate through metal.
2. If you see this symbol then the thermostat is connected to your Pelican Wireless
Mesh Network, but your Pelican Gateway is unable to reach the Internet.
• Check your Pelican Gateway to verify it is installed, powered on, and has Internet
connection.
If you are unable to get the thermostat to connect to the wireless mesh network or
Internet, contact Pelican technical support for further assistance at 888.512.0490.
