THERMOSTAT LOCATION

To ensure proper operation, the thermostat should be mounted on an inside wall in a frequently occupied area of the space. In addition, its position must be at least 18” (46 cm) from any outside wall, and approximately 5’ (1.5 m) above the floor in a location with freely circulating air of an average temperature.

Be sure to avoid the following locations:

• Behind doors or in corners where freely circulating air is unavailable
• Where direct sunlight or radiant heat from appliances might affect control operation
• On an outside wall
• Adjacent to, or in line with, conditioned air discharge grilles, stairwells, or outside doors
• Where its operation may be affected by steam or water pipes or warm air stacks in an adjacent partition, or by any unheated/uncooled area behind the thermostat
• Where operation may be affected by lighting dimmers
• Where operation will be affected by the supply air of an adjacent unit
• Near electrical source interference such as arcing relay contacts

MOUNT THERMOSTAT BACKPLATE

BEFORE YOU BEGIN:
Turn off the power to the HVAC equipment.

TIP:
If you are replacing an existing thermostat, take a picture of the thermostat wiring for reference.

1. From the factory, the thermostat faceplate is not firmly connected to the backplate. While holding the thermostat, firmly near the bottom, gently pull apart the backplate from the faceplate.
2. Place the rectangular opening in the backplate over the equipment control wires protruding from the wall. Use the backplate as a template and mark the location of the two mounting holes.
3. Use the supplied anchors and screws for mounting on drywall or plaster; drill two 3/16” (5mm) diameter holes at the marked locations; tap the nylon anchors flush to the wall surface and fasten the backplate using the supplied screws.
   • WARNING:
     Do not over-tighten the screws!
4. Connect the wires from your system to the thermostat terminals as shown in the Wiring Diagrams section of this manual. Carefully dress the wires so that any excess is pushed back into the wall cavity or junction box. Ensure that the wires are flush with the plastic backplate. The access hole should be sealed or stuffed to prevent drafts from affecting the thermostat.
   • Reattach Faceplate
5. Reattach the faceplate to the backplate by placing the top of the faceplate over the top lip of the backplate.
6. Gently swing the thermostat down and press on the bottom center edge until it snaps in place. This is a tight connection but may require a little wiggle to align the pins on the faceplate with the screw terminals on the backplate before it snaps into place.
7. Reconnect power to the HVAC equipment. You are now ready to configure your thermostat for operation.

WARNING:
Your thermostat is NOT ready to use. You must complete the Thermostat Setup section before using the thermostat. Failure to do this can result in damage to your equipment.

REMOTE SENSORS

• If your NetX™ thermostat has been installed with one or more
• NetX™ remote sensors, the sensor information is available on the small secondary display of the thermostat. There are many different remote sensor options.
• You can view the remote sensor information by tapping the upper left part of the display to view different attached remote sensors.
• The X5-CFA thermostat uses one or more NT-ROOM-S remote sensors for temperature control. See the NT-ROOM-S installation instructions for details.

NOTE:
If no remote sensors are detected, the thermostat will default to the internal temperature sensor.

• RS1 – RS2 – RS+V Terminals / Remote Sensor Bus
  Used for connection of a wide variety of NetX™ remote sensors. See NetX sensor instructions for use.
• NOTE:
  If no remote sensors are detected, the thermostat will default to the internal temperature sensor.
• Emergency Heat Indicator
  The thermostat is equipped with an Emergency Heat icon Q in the Current Operation Status Icon area on the faceplate that indicates when the system has engaged emergency heat mode.
• Random Restart
  After a power failure, the thermostat will delay the HVAC equipment start-up by 1-24 seconds. When multiple NetX™ X-Series thermostats are used, this minimizes the “in rush” current (electric power usage) as it reduces the number of HVAC units that will be turned on simultaneously.
• Power Failures
  This NetX™ X5-CFA thermostat will maintain the operation settings during any type of power failure. When power is restored the thermostat will return to the last MODE (Heat, Cool, Auto, Off) and the Occupied setpoints. If the CLK terminals are shorted at power up, the thermostat will operate using the last Unoccupied setpoints.
