Wall Sensor- Installation & Initial Setup

| Overview

The Wall Sensor adds a high-precision temperature and humidity sensor to the network, pre-calibrated from the factory. 

| Precautions

• Install as per all state and local electrical codes.
• Do not mount the sensor head too close to the ceiling, this increases the stratification effect.
• Do not mount the sensor exposed to direct sunlight or any other heat source.

| Mounting

Mount the Wall Sensor on a wall by a single toggle bolt.   

| Wiring

The sensor plugs into the standard 3wire sensor bus that 75F offers on its Nodes and Stats, using the wiring harness shown below.

• Connect the 3 Pin connector to the sensor as shown below

The Wall Sensor can be made a part of the Daisy Chain as Below.

Note: Combining it with other sensors in the bus, using the daisy chain adapter, and with 3 Pin to 3 Pin cable of lengths 18 inches, 20, 30, and 50 feet,

For more information on the Daisy Chaining capability refers to Daisy Chaining Capabilities of Sensors

| Wall Sensor Communication with 100 ft Sensor Bus Cable

For 100 ft sensor bus cable installations, an additional resistor may be required to ensure reliable wall sensor communication. Refer to Smart Node V2: Wall Sensor Communication with a 100 ft Sensor Bus Cable for installation instructions and the wiring illustration.

| More Information

Remove the top cover of the Wall Senso to access additional capabilities.

• Press the button at position 1 to reset the sensor.
• Press the button at position 2 to set the Master device to pairing mode, without having to access the device installed at the plenum in the building (press the button somewhere between 4 to 8 seconds).
