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 configurable energy-saving settings allow for customization of the thermostat energy-saving settings to fit any situation.
Comprehensive configuration 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 THE 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 THE CONNECTION KIT MUST BE WHITELISTED USING 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.
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.
Connecting the Ethernet Cable
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.
Configuring the Online Connection Kit
Installing the HVAC Controller in an HVAC Unit
THE HVAC CONTROLLER ANTENNA MUST BE FACING THE THERMOSTAT AND MUST NOT BE TOUCHED OR ENCLOSED BY ANY METAL COMPONENTS IN THE HVAC UNIT.
THE HVAC CONTROLLER MUST BE MOUNTED SO IT CANNOT FALL INTO THE HVAC UNIT CONDENSATION PAN. WE RECOMMEND USING PLASTIC CABLE TIES, OR 3M COMMAND TAPE (NOT SUPPLIED).

NOTE: If the HVAC unit has only one (1) fan speed, connect both fan control wires – Green and Purple – to the fan terminal (G).
For Installation on PTAC Units;
For other units;
For Fan Coils;
IF THE HVAC UNIT VOLTAGE OUTPUT IS MORE THAN 30VAC, YOU WILL REQUIRE A HIGH-VOLTAGE HVAC CONTROLLER (VX-HV-CC).*
PLEASE VERIFY THAT YOU HAVE THE CORRECT PARTS BEFORE BEGINNING INSTALLATION. IF YOU DO NOT HAVE THE CORRECT PARTS, CEASE INSTALLATION IMMEDIATELY AND CALL VERDANT TECHNICAL SUPPORT AT 1 877 318 1823.
Mounting the Thermostat to the Wall
With the thermostat and HVAC unit powered, follow the configuration instructions to correctly configure the thermostat.
To ensure proper operation of the HVAC unit, complete the following steps.
Accessing the Configuration Screen
NOTE: You can access Thermostat Configuration settings at any time by pressing the “Configuration” button.
The thermostat configuration screens have a 30-second time-out. If no action is taken within (30) seconds, the thermostat will exit configuration settings.
NOTE: When the thermostat is connected to a network, the equipment and the energy-saving settings configured on the thermostat will be overridden by settings configured online.
The thermostat and HVAC Controller must be paired during installation. The thermostat will search for the closest HVAC Controller to it and display the unique HVAC Controller ID. The HVAC Controller ID is located on the case.
THE WIRELESS CONTROLLER MUST BE LINKED TO A THERMOSTAT IN THE SAME ROOM. ONLY INSTALL ONE ROOM AT A TIME.
Setting the MESH ID
Entering the Room Number
Enter the room number by changing the characters on the screen.
Available characters include digits 0-9 and letters A-F. To distinguish between two or more thermostats in the same unit, enter as follows:
Configuring the Equipment Settings
Enter the equipment code by changing the digits on the screen. Refer to the table below.
Digit | Setting #1 Compressor Type | Setting #2 Electric Heat | Setting #3 Reversing Valve | Setting #4 Fan Speed |

E-2 | Lower Energy Savings |
E-3 | Standard Energy Savings |
E-4 | Higher Energy Savings |
E-5 | Highest Energy Savings |
*Indicates default setting.
Setting the thermostat clock
Set the thermostat clock to current time in 24h (Military Time) format.
Testing the Thermostat
Following the thermostat configuration, test if the thermostat is controlling the HVAC unit.
Replacing Thermostat Batteries
The low battery indicator will be displayed on the thermostat screen when it is necessary to replace batteries in the thermostat.
Under normal operating conditions, new brand-name alkaline batteries will last for a period of approximately eighteen (18) months.
Please replace batteries every sixteen (16) months to ensure continuous thermostat operation.
To replace thermostat batteries:
With the thermostat and HVAC unit powered, follow the sensor confi guration instructions to correctly confi gure the sensors.
Activating a Sensor
Discovering an Active Sensor
The thermostat will display the first sensor discovered in the pairing process. Ensure that the unique device number displayed on the screen matches the unique ID found on the sensor.
Configure the Functionality of a Sensor
The thermostat allows the user to change the default functionality of the sensor. Use the table below to configure the desired functionality.
Functionality | Sensor Functionality Code |
Occupancy Sensor | 100 |
Sensor with Magnetic door switch | 010* |
Temperature Sensor | 001 |
*Indicates default setting.
Completing the Sensor Setup
The thermostat will count down from thirty (30) seconds. If the sensor has successfully paired, the thermostat will display “SUCC”. If the sensor did not pair successfully, the display will read “FAIL”, and the process must be repeated.
