NOTICE
FOR 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 THE 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 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 – the jumper is connecting the “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 – the jumper is connecting the “COM” and “C” pins.

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 the 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.
