Introduction
Verdant VX Series Energy Management Thermostats for the hospitality
industry deliver unprecedented energy savings without compromising
guest comfort.
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 hospitality HVAC system with up to 2
heat and 1 cool stages.
Built-in wireless mesh-networking enables online management.

Before You Begin
➤ Determine the appropriate installation location for the thermostat.
➤ 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.
➤ Consult the HVAC manufacturer’s documentation or use a voltmeter
to determine if the HVAC unit outputs AC or DC power (24V).
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.
THE THERMOSTAT SHOULD FACE THE BED AREA OF THE ROOM.
THE 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.
NOTICE
FOR INSTALLATION OF THERMOSTATS WITH NETWORKING
CAPABILITIES, REFER TO THE “VX-TW NETWORK INSTALLATION”
MANUAL.
BEFORE INSTALLING THERMOSTATS, CONFIRM WITH A VERDANT
TECHNICAL SUPPORT AGENT THAT THE SERVER IS CONNECTED
TO THE INTERNET BY CALLING 1 877 318 1823.
DO NOT INSTALL THERMOSTATS IF THE SERVER IS NOT
CONNECTED TO THE INTERNET. STOP THE INSTALLATION
AND CONTACT VERDANT TECHNICAL SUPPORT FOR FURTHER
DIRECTION.

Thermostat Installation
Installing the Wireless Control Card
➤ Power Off HVAC unit;
➤ Connect the control card to the thermostat terminals on the HVAC
unit - refer to the Wiring Table to determine proper connections.
➤ Mount the control card inside of the HVAC unit.
THE WIRELESS CONTROL CARD ANTENNA MUST NOT BE TOUCHING
ANY METAL COMPONENTS OF THE HVAC UNIT.
THE 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.
THE 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.
Before You Begin
Pairing the Thermostat and the Control Card
The thermostat and Control Card must be paired in order to operate
together. Once paired, the thermostat cannot be used with another
wireless control card without repeating the pairing procedure.
In case of Network Installation with online management, the
thermostat and the Control Card must be paired with a Network
Programmer specific to the property before the installation.
The thermostat and control card must not be powered during the pairing
procedure - remove batteries from the thermostat and unplug the control
card from the HVAC unit during the pairing procedure.
➤ Plug one programmer connector into the thermostat;
➤ Plug the other programmer connector into the control card;
➤ Push the black button on the programmer. The red light on the
programmer should turn on and remain steadily lit;
If the red light on the programmer is blinking or is not steadily lit,
unplug the programmer from the thermostat and the control card
and repeat the steps above.
➤ Unplug the programmer from the thermostat and the control card;
NOTE: If the PTAC unit has only one (1) fan speed, connect both fan
control wires – Green and Purple – to the fan terminal (G).
