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.

NOTICE

FOR INSTALLATION OF NETWORKING THERMOSTATS WITH REMOTE MANAGEMENT, REFER TO THE “VX-TW NETWORK INSTALLATION” MANUAL.

Energy saving presets eliminate the guesswork and make it easy to adjust the energy saving settings. (Patent Pending)

Fully conﬁgurable energy saving settings allow for customization of the thermostat energy saving settings to ﬁt any situation.

Large buttons with international symbols make it easy to adjust the temperature in ±1° °F or °C and control the fan speed.

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 optional remote management.

DO NOT INSTALL THERMOSTATS IF THE SERVER IS NOT CONNECTED TO THE INTERNET. STOP THE INSTALLATION AND CONTACT VERDANT TECHNICAL SUPPORT.

START BY FIRST INSTALLING A THERMOSTAT IN THE ROOM CLOSEST TO THE SERVER.

LOG IN TO VERDANT’S REMOTE MANAGEMENT WEBSITE TO CONFIRM THAT THE THERMOSTAT IS ON THE REMOTE MANAGEMENT WEBSITE WITH THE CORRECT ROOM NUMBER.

CONTINUE BY INSTALLING ADDITIONAL THERMOSTATS IN ADJACENT ROOMS ONLY AFTER CONFIRMING THAT INSTALLED THERMOSTAT(S) HAVE CONNECTED TO THE WIRELESS NETWORK AND THE REMOTE MANAGEMENT WEBSITE .

IF INSTALLED THERMOSTAT(S) ARE NOT CONNECTING TO THE NETWORK AND DO NOT APPEAR ON THE VERDANT’S REMOTE MANAGEMENT WEBSITE WITH THE CORRECT ROOM NUMBER, STOP THE INSTALLATION AND CONTACT VERDANT TECHNICAL SUPPORT

THE ROOMS FURTHEST AWAY FROM THE SERVER SHOULD BE INSTALLED LAST.

Before You Begin

➤ Determine the appropriate installation location for the thermostat.

THE THERMOSTAT SHOULD FACE THE BED AREA OF THE ROOM.

THE THERMOSTAT AND CONTROL CARD MUST NOT BE INSTALLED NEAR OR ON METAL STRUCTURES OR SURFACES INCLUDING METAL AIR DUCTING THAT MAY BE IN THE WALL.

WIRELESS CONTROLS CARDS MUST BE MOUNTED AWAY FROM METAL AND METAL ENCLOSURES. VTAC INSTALLATIONS SHOULD MOUNT THE CONTROL CARD ABOVE THE UNIT’S METAL ENCLOSURE.

METAL STRUCTURES AND SURFACES SIGNIFICANTLY REDUCE THE RANGE OF THE WIRELESS SIGNAL.

➤ 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 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.

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 Remote 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.
