Verdant VX-TW Network Installation
Whitelisting the Server
THE SERVER REQUIRES A LIVE ETHERNET PORT FOR MAC ADDRESS PRINTED
ON THE SERVER WITH DHCP AND THE ABILITY TO CONNECT OUTWARD VIA
TCP TO A REMOTE MACHINE.
CONTACT THE PROPERTY SYSTEM ADMINISTRATOR TO WHITE LIST
THE SERVER MAC ADDRESS FOR CONNECTING TO THE INTERNET.
THE SERVER MAC ADDRESS IS PRINTED ON THE SERVER.

Installing the Online Connection Kit
BEFORE YOU BEGIN
1. Connecting the Antenna Module
1.1. Screw the Antenna onto the Wireless Receiver;
1.2. Connect the Wireless Receiver to the Server using the supplied USB
cable;
1.3. Fix the Wireless Receiver to the wall with double-sided adhesive
tape.
Orient the antenna to be parallel to the closest room in which
Verdant thermostat will be installed;
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.
DETERMINE THAT THE SERVER INSTALLATION LOCATION IS SUITABLE.
INSTALL THE SERVER IN A ROOM ADJACENT TO ROOMS IN WHICH
VERDANT THERMOSTATS WILL BE INSTALLED. THE MAXIMUM
DISTANCE WILL VARY DEPENDING ON THE TYPE OF THE BUILDING
CONSTRUCTION.
DO NOT INSTALL THE SERVER IN THE BASEMENT

2. Connecting the Ethernet Cable
2.1. Connect the Server to the LAN port with the supplied RJ-45 cable;
3. Powering on the Server
3.1. Plug the Server into an electrical outlet with the supplied power cord;
TO PREVENT POWER RELATED ISSUES PLUG THE SERVER INTO A UPS
(UNINTERUPTED POWER SUPPLY) UNIT.
LOGIN TO THE REMOTE MANAGEMENT WEBSITE TO CONFIRM THE
SERVER IS CONNECTED TO THE INTERNET. IF THE SERVER IS NOT
CONNECTED TO THE INTERNET, STOP THE INSTALLATION AND
CONTACT VERDANT TECHNICAL SUPPORT.

8Verdant VX-TW Network Installation
Installing Thermostats
START BY FIRST INSTALLING A THERMOSTAT IN THE ROOM CLOSEST
TO THE SERVER.
CONTINUE BY INSTALLING ADJACENT ROOMS ONLY AFTER
CONFIRMING THAT INSTALLED THERMOSTAT(S) HAVE CONNECTED
TO THE WIRELESS NETWORK.
THE ROOMS FURTHEST AWAY FROM THE SERVER SHOULD BE
INSTALLED LAST.
DETERMINE THE APPROPRIATE INSTALLATION LOCATION FOR THE
THERMOSTAT - THE THERMOSTAT SHOULD FACE THE BED AREA OF
THE ROOM.
THERMOSTAT MUST NOT BE INSTALLED NEAR OR ON 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.

4. Pairing the Thermostat and the Wireless Control Card
4.1. Plug one Network Programmer connector into the T-shape opening
on the Thermostat;
4.2. Plug the other Network Programmer connector into the T-shape
opening on the Wireless Control Card;
4.3. Push the Black Button on the Network Programmer.
The red light on the Network Programmer will turn on and remain
steadily lit;
If the red light on the Network Programmer is blinking or is not
steadily lit, the thermostat and the control cards have not been
programmed correctly. Unplug the Network Programmer connector
from the thermostat and the control card and repeat the steps
above.
4.4. Unplug the Network Programmer from the thermostat and the
control card;
THERMOSTAT AND CONTROL CARD MUST NOT BE POWERED
DURING THE PAIRING PROCEDURE. DO NOT INSERT BATTERIES IN
THE THERMOSTAT AND DO NOT CONNECT THE CONTROL CARD TO
THE HVAC UNIT DURING THE PAIRING PROCEDURE.

5. Installing the Wireless Control Card
5.1. Set the HVAC unit to “External Thermostat” (Class 2) mode. Consult
the HVAC unit documentation to determine how to set the HVAC
unit to “External Thermostat” mode.
5.2. Power Off the HVAC unit;
5.3. Connect the Wireless Control Card to the thermostat terminals on the
HVAC unit.
Refer to the Wiring Tables to determine proper wiring.
Use the supplied molex connector to connect to HVAC units with pin
connectors.
Clip and strip wires to connect to HVAC units with screw-terminals.
5.4. Mount the control card inside of the HVAC unit.
5.5. Power On the HVAC unit.

control wires – Green and Purple –
to the fan terminal (G).
IF THE HVAC UNIT OUTPUTS AC POWER, MAKE SURE THAT THE
JUMPER ON THE WIRELESS CONTROL CARD IS IN THE AC POSITION -
JUMPER IS CONNECTING “R” AND “COM” PINS (DEFAULT).
IF THE HVAC UNIT OUTPUTS DC POWER, MAKE SURE THAT THE
JUMPER ON THE WIRELESS CONTROL CARD IS IN THE DC POSITION -
JUMPER IS CONNECTING “COM” AND “C” PINS.
WIRELESS CONTROL CARD ANTENNA MUST NOT BE TOUCHING ANY
METAL COMPONENTS OF THE HVAC UNIT.
WIRELESS CONTROL CARD ANTENNA MUST FACE THE THERMOSTAT
ON THE WALL AND BE ORIENTED SO THAT ANY METAL
PARTS OF THE HVAC UNIT DO NOT OBSTRUCT THE WIRELESS
COMMUNICATION TO THE THERMOSTAT AND, IN CASE OF A
NETWORK INSTALLATION, TO OTHER WIRELESS CONTROL CARDS
AND THE SERVER.
WIRELESS CONTROL CARD MUST NOT BE PLACED IN THE HVAC
UNIT CONDENSATION PAN AND MUST BE MOUNTED SO IT CANNOT
FALL INTO THE HVAC UNIT CONDENSATION PAN.
