4 5IntroductionVerdant 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. (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. NOTICEFOR INSTALLATION OF NETWORKING THERMOSTATS WITH REMOTE MANAGEMENT, REFER TO THE “VX-TW NETWORK INSTALLATION” MANUAL.LOGIN TO THE REMOTE MANAGEMENT WEBSITE TO CONFIRM THE SERVER IS CONNECTED TO THE INTERNET BEFORE INSTALLING THERMOSTATS. 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 SUPPORTTHE ROOMS FURTHEST AWAY FROM THE SERVER SHOULD BE INSTALLED LAST.
6 7Before 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 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 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.Before You Begin Pairing the Thermostat and the Control CardThe 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. ➤Unplug the programmer from the thermostat and the control card;

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. ➤Power On the HVAC unit.Mounting the thermostat to the wall ➤Remove the thermostat cover; ➤Use the supplied wall anchors and mounting screws to secure the thermostat to the wall; ➤Insert two (2) AA-cell batteries (not supplied) into the thermostat battery compartment; ➤Follow the “Thermostat Configuration” instructions; ➤Replace the thermostat cover and screw in the locking screw;Thermostat Installation
CONFIGURATION BUTTONNOTE: You can access Thermostat Configuration settings at any time by pressing the “Configuration” button. 10 11Thermostat ConfigurationOnce the thermostat is powered, thermostat configuration settings will appear on the thermostat screen.In order to properly operate the HVAC unit: ➤Set the thermostat clock; ➤Enter the room number; ➤Configure the equipment settings; ➤Select Energy Savings Preset;The thermostat configuration screens have a 30-second time-out. If no action is taken within three (30) seconds, the thermostat will exit configuration settings.NOTE: If the thermostat is connected to a network, the equipment and the energy saving settings configured on the thermostat will be ignored and the settings configured on the Remote Management Website will be applied.Thermostat ConfigurationSetting the thermostat clockSet the thermostat clock to current time in 24h (Military Time) format. ➤Use the “Up” and “Down” buttons to set the hours; ➤Press the “Fan” button to advance to the minutes setting; ➤Use the “Up” an “Down” buttons to set the minutes; ➤Press the “F/C” button to advance to the next menu;Setting the clock correctly is crucial for proper operation of the thermostat.HOURS MINUTES

18 19Thermostat MaintenanceReplacing Thermostat BatteriesThe 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 one (1) year. Please replace batteries every twelve (12) months to ensure continuous thermostat operation.To replace thermostat batteries: ➤Unscrew the fixing screw and remove the thermostat cover; ➤Replace the two (2) AA-cell batteries (not-supplied); ➤Replace the thermostat cover and screw in the fixing screw; ➤Follow the “Thermostat Configuration” instructions to set the thermostat clock; ➤Press the “Power” button to start using the thermostat;NOTE: The thermostat maintains all the “Thermostat Configuration” settings in a non-volatile memory. There is no need to configure the thermostat again after battery replacement.Error CodesERR 1 Thermostat Temperature Sensor Hardware Defect ERR 2 Thermostat Radio Hardware Defect ERR 3 Thermostat Radio Software Defect ERR 4 No link with the Wireless Control Card ERR 5 Thermostat Memory DefectTroubleshooting
20 21The Thermostat is not controlling the HVAC unit.Check if the HVAC unit is set to “External Thermostat” (Class 2) mode. Verify the status of the red light on the Wireless Control Card; ➤The red light is off The Wireless Control Card is not powered. Verify that the Wireless Control Card is properly wired to the HVAC unit - specifically make sure that the RED and the BLACK wires are properly connected; ➤If the red light is blinking with one (1) flash The Wireless Control Card is powered but it is not communicating with the thermostat, turn the thermostat off and on to re-initiate the linking procedure. In case of a Network Installation, re-link the thermostat and the Wireless Control Card with the Network Programmer. ➤The red light is blinking with three (3) flashes. The Wireless Control Card is communicating with the thermostat. Verify that the Wireless Control Card is properly wired to the HVAC unit and that equipment settings on a thermostat - compressor type, electric heat and reversing valve - are properly configured.
