Introduction
Verdant VX Series Energy Management Thermostats deliver unprecedented energy
savings without compromising the comfort of occupants.
An integrated occupancy sensor uses a combination of motion and thermal sensing
technologies for accurate occupancy detection. Reliable occupancy detection allows
for energy savings when rooms are unoccupied.
Energy saving presets eliminate the guesswork and make it easy to adjust the energy
saving settings.
Fully congurable energy saving settings allow for customization of the thermostat
energy saving settings to t any situation.
Comprehensive conguration options ensure full compatibility with virtually any
existing or emerging HVAC system with up to 2 heat and 1 cool stages.
Built-in wireless mesh-networking enables online management.

NOTICE
TO ENABLE NETWORKING CAPABILITIES OF THE VX THERMOSTAT, REFER
TO THE “NETWORK INSTALLATION” SECTION OF THIS MANUAL.
BEFORE STARTING THE INSTALLATION OF THE NETWORKED THERMOSTATS,
ENSURE THAT THE ONLINE CONNECTION KIT IS CONNECTED TO THE
INTERNET.
THE ONLINE CONNECTION KIT MUST BE PLUGGED INTO AN INTERNET
PORT WITH A STATIC IP ADDRESS WITH DHCP ACTIVE. THE ONLINE
CONNECTION KIT MUST BE WHITELISTED USINGS ITS MAC ADDRESS
WITH UNRESTRICTED INTERNET ACCESS. INBOUND/OUTBOUND
COMMUNICATION PORTS ARE 80,443, AND 22.
PLEASE CONFIRM WITH A VERDANT TECHNICAL SUPPORT AGENT THAT
THE ONLINE CONNECTION KIT IS COMMUNICATING PROPERLY WITH THE
CLOUD SERVICE BY CALLING OUR TECHNICAL SUPPORT TEAM AT 1 877 318

Network Installation
Connecting the Antenna Module
➤Screw the Antenna onto the Wireless Receiver;
➤Connect the Wireless Receiver to the Server using the supplied USB cable;
➤Afx the Wireless Receiver to the wall with double sided adhesive tape (not
supplied);
➤Orient the antenna to be parallel to the closest room in which a Verdant
thermostat will be installed.
THE WIRELESS RECEIVER AND THE ANTENNA MUST NOT BE INSTALLED NEAR
METAL STRUCTURES OR SURFACES.
METAL STRUCTURES AND SURFACES SIGNIFICANTLY REDUCE THE RANGE OF THE
WIRELESS SIGNAL.

8
Connecting the Ethernet Cable
➤Connect the Server to the LAN port with the supplied RJ-45 cable.
Network Installation

9
Network Installation
Powering on the Server
➤Plug the Server into an electrical outlet with the supplied power cord.
TO PREVENT POWER RELATED ISSUES, PLUG THE SERVER INTO A UPS
(UNINTERRUPTED POWER SUPPLY) UNIT.

10
Network Installation
Conguring the Online Connection Kit
➤Ensure the Online Connection Kit is receiving a Static IP address via DHCP
Server. A public IP will not work;
➤Ensure that the MAC address is properly Whitelisted if it needs to bypass
a login (splash) page to be able to reach the internet. The MAC address is
printed on a white sticker on the bottom of the Online Connection Kit.
➤The Online Connection Kit’s open TCP ports are 22, 80, and 443.

11
THE THERMOSTAT’S OCCUPANCY SENSOR SHOULD FACE THE BED AREA OF
THE ROOM OR THE AREA WHERE THE OCCUPANT WILL SPEND THE MOST
TIME.
THE THERMOSTAT MUST NOT BE INSTALLED IN THE VICINITY OF METAL
STRUCTURES OR SURFACES INCLUDING METAL AIR DUCTING THAT MAY BE
IN THE WALL.
METAL STRUCTURES AND SURFACES SIGNIFICANTLY REDUCE THE RANGE
OF THE WIRELESS SIGNAL.
DO NOT OVER TIGHTEN THE BACK PLATE TO THE WALL. FOR UNEVEN
SURFACES, CONSIDER INSTALLING A WALL PLATE.
Mounting the Thermostat to the Wall
➤Select the appropriate installation location for the thermostat, taking into
account the following;
➤With the faceplate removed, place the thermostat on the wall in the
installation location and mark location for drilling holes for the two (2)
mounting screws;
➤Drill two (2) 3/16” holes in the wall and insert the two (2) supplied wall
anchors;
➤Use the two (2) supplied screws to securely mount the thermostat to the wall;
➤Insert two (2) AA-cell batteries (not supplied) into the thermostat battery
compartment;
➤Follow the “Thermostat Conguration” instructions;

Occupancy Sensor Installation
Mounting the Occupancy Sensor (Optional)
➤Select the appropriate installation location for the external occupancy sensor,
taking into account the following;
➤With the faceplate removed, place the sensor on the wall in the installation
location and mark location for drilling holes for the two (2) mounting screws;
➤Drill two (2) 3/16” holes in the wall and insert the two (2) supplied wall
anchors;
➤Use the two (2) supplied screws to securely mount the sensor to the wall;
➤Insert (2) AA batteries into the compartment (not supplied - wireless sensors
only)
THE OCCUPANCY SENSOR SHOULD FACE THE DESIRED OCCUPANCY
DETECTION AREA.

13
Occupancy Sensor Installation
Installing the Wireless Sensor Receiver (Optional - Wireless Sensors Only)
➤Plug the Sensor Receiver and plug it into the thermostat;
➤With the faceplate removed, place the sensor on the wall in the installation
location and mark location for drilling holes for the two (2) mounting screws;
➤Drill two (2) 3/16” holes in the wall and insert the two (2) supplied wall
anchors;
➤Use the two (2) supplied screws to securely mount the sensor to the wall;
➤Insert (2) AAA batteries into the compartment (wireless sensors only)

14
Occupancy Sensor Wiring
Wiring the Occupancy Sensor (Optional - Wired Sensors Only)
➤Fish the wire from the back of the occupancy sensor to the thermostat
location.
➤Connect the wiring from the sensor to the wire harness already plugged into
the thermostat port. Extra wire and wire nuts are not supplied.
