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

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.
   ℹ

   NOTE: There are several versions of the X-Series thermostat. The wiring instructions for the equipment are identical.
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.
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.

LED1 / Filter Indicator

If selected by software, the Filter Icon will illuminate when a signal is received from the Terminal LED1 on the Terminal block. This indicates the filter needs to be changed. Otherwise, the status of Terminal LED1 will be reported on the Status Update page of the thermostat.

LED2 / Service Indicator

If selected by the software, the Service Indicator icon will illuminate when a signal is received from Terminal LED2 on the terminal block. This terminal is normally connected to the L terminal on a heat pump. When a signal is received, the WRENCH icon will display on the thermostat screen, indicating that service is required.

Auxiliary/Emergency Heat Indicator

The thermostat is equipped with the Emergency Heat icon in the Main Status Icons area on the faceplate, which indicates when the system has engaged auxiliary heat mode or emergency heat mode.

Random Restart

After a power failure, the thermostat will delay the heating/cooling equipment start-up by 1–24 seconds. When multiple 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

The X-Series thermostat has an internal power backup that will last approximately two days. If the thermostat experiences a power outage less than this time, all functions will resume as soon as power is restored. If the power outage lasts longer, upon power restoration the thermostat will recover depending on the following factors:

• Time set via NTP (Network Time Protocol): When the power is restored and the thermostat connects to the internet, it will resume normal programmed operation.
• Time set manually: When power is restored, the clock will flash 12:00 and will operate in Manual Mode until the time is set. After the time has been set, the thermostat will resume normal programmed operation.

Occupancy Control

Occupancy control settings are available on the Sensor Settings web page and via the Installer Menu. These settings define how the thermostat responds to occupancy input on the CLK1/CLK2 terminals.

Remote Sensors (Optional)

If your thermostat has been installed with one or more 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.

RS1 – RS2 – RS+V: Remote Sensor Bus

Used for connection of a wide variety of remote sensors, allowing installation flexibility and additional information from the communications bus. It also allows the thermostat to be placed in an area away from view.

Sensor Types

The following sensor types are supported and configured by name on the Sensor Settings web page of the thermostat. Click UPDATE to apply changes.

Remote Sensor Averaging

If remote temperature sensors are connected, the thermostat can either use the remote sensors (default) or average the remote sensor and the internal temperature sensor. The Remote Sensor Averaging setting can be accessed from the HVAC Settings web page of the thermostat.

On-Board Data Logging with Sub-Metering Support

The NetX Platform provides reliable deep-data analysis for runtimes and all thermostat operations. This data can be used to perform sub-metering analysis to bill tenants according to actual HVAC usage for heating and cooling. Onboard memory supports approximately 30 days of records.
