Table of Contents 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.

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.

THE THERMOSTAT SHOULD NOT BE INSTALLED DIRECTLY ABOVE OR BELOW

THE HVAC SYSTEM AS IT MAY CAUSE FALSE TEMPERATURE READINGS.

PLEASE ENSURE THAT THE INSTALLATION RESPECTS THE LOCAL ELECTRICAL

CODE. IF IN DOUBT, CONSULT A CERTIFIED ELECTRICIAN TO ENSURE YOUR

INSTALLATION IS CODE COMPLIANT.

Before You Begin

Installation on a Bare Wall

➤Select the appropriate installation location for the thermostat. Refer to

installation considerations section of this manual;

➤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.

Installation Using a Wallplate

➤Select the appropriate installation location for the thermostat. Refer to

installation considerations section of this manual;

➤Place the wallplate over the hole in the wall left by the previous thermostat,

and mark two locations for drilling holes;

➤Drill two (2) 3/16” holes in the wall and insert the two (2) supplied wall

anchors;

➤Mount the wallplate to the wall using the two (2) supplied screws.

➤With the faceplate removed, place the thermostat on the wallplate in the

installation location and screw the thermostat onto the wallplate;

➤Insert two (2) AA-cell batteries (not supplied) into the thermostat battery

compartment.

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 PRIVATE IP ADDRESS WITH DHCP ACTIVE. THE ONLINE

CONNECTION KIT MUST BE WHITELISTED USINGS ITS MAC ADDRESS WITH

UNRESTRICTED INTERNET ACCESS. PORTS 80,443, AND 22 MUST BE OPEN

TO INBOUND/OUTBOUND COMMUNICATION.

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

1823.

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;

➤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.

12 13

Connecting the Ethernet Cable

➤Connect the Server to the LAN port with the supplied RJ-45 cable.

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.

Network Installation

14 15

Network Installation

Conguring the Online Connection Kit

➤Ensure the Online Connection Kit is receiving a Private or 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 ports are 22, 80, and 443.

HVAC Controller Installation

High voltage HVAC Controller installation

The high voltage HVAC Controller can control HVAC units that would typically use

line voltage controls.

The HVAC Controller outputs are the same voltage as the incoming power source.

Insert the threaded hub through a knock-out hole of your enclosure. Use a standard

locknut to secure the HVAC Controller to the enclosure.

The connections between the HVAC unit and the HVAC Controller will be terminated

inside the enclosure. Please ensure the installation respects the prevalent local

electrical code.

The occupancy output of the HVAC Controller (i.e. a relay output that energizes

when the room is occupied) will also produce the same voltage as the incoming

power source. If this signal needs to be used with other systems, please install a relay

whose coil voltage requirements matches the incoming power source of the HVAC

Controller.

Take note of the serial number on the HVAC Controller before closing the enclosure.

This number is necessary to pair the HVAC Controller with the Verdant thermostat in

the same room.

THE HVAC CONTROLLER ANTENNA MUST BE FACING THE THERMOSTAT AND

MUST NOT BE TOUCHING OR ENCLOSED BY ANY METAL COMPONENTS IN THE

HVAC UNIT.

THE HVAC CONTROLLER MUST BE MOUNTED OUTSIDE OF ANY EXISTING METAL

ENCLOSURE BY USING THE THREADED HUB BUILT INTO THE HVAC CONTROLLER.

16 17

HVAC Controller Installation

High voltage HVAC Controller installation (cont’d)

The thermostat can control units using line voltage valves (heating and cooling) and

2 fan speeds.

➤Connect cooling valve to terminal 2 and terminal 5 (black and yellow wires);

➤Connect heating valve to terminal 2 and terminal 4 (black and white wires);

➤Connect High Fan speed to terminal 2 and terminal 9 (black and green wires);

➤Connect Low Fan speed to terminal 2 and terminal 8 (black and purple wires);

Thermostat Installation

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.

Con guring the Thermostat

With the thermostat and HVAC unit powered, follow the con guration instructions

to correctly con gure the thermostat.

To ensure proper operation of the HVAC unit, complete the following steps.

➤Pair the thermostat with the HVAC Controller

➤Set the MESH ID;

➤Enter the room number;

➤Enter the equipment code;

➤Con gure the energy saving settings;

➤Set the thermostat clock

Thermostat Con guration

Accessing the Con guration Screen

➤Ensure the thermostat is powered and faceplate removed;

➤Press the con g button;

The thermostat con guration screens have a 30-second time-out. If no action is

taken within (30) seconds, the thermostat will exit con guration settings.

NOTE: When the thermostat is connected to a network, the equipment and

the energy saving settings con gured on the thermostat will be overidden by

settings con gured online.
