| Overview

The 75F BMS supports a portfolio of products that are used to provide Intelligent building automation in the HVAC space. This portfolio of products also comprises a set of sensors. These sensors sense various parameters in the rooms and supplies to the room controllers (Nodes & Stats).

The 75F in its vision towards energy savings and Occupant comfort stands out in its capability of micro zoning and room level controls. That being said 75F added several sensors to the portfolio, that would help meet the demands of the vision, to provide excellent room-level control and comfort.

Below is the list of sensors of 75F.

  • Local Interface Sensors
  • Wall Sensor
  • Ceiling Sensor
  • Flush Mount Sensor
  • Differential Pressure Sensor
  • Duct Sensor V2.0
  • Duct Sensor V1.0
  • Wired Multi-Sensor

| Local Interface Sensor

The Local Interface Sensor is a room sensor and user interface. By default, it measures the temperature, humidity, and light in a zone. It can be extended to control HVAC equipment by connecting it SmartNode or SmarStat. For more information refer to Local Interface Sensor Overview

| Wall Sensor

The Wall Sensor is an Intelligent-Remote Temperature and Humidity Sensor (RTH). It adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. it is easily mounted on a wall by a single toggle bolt. For more information refer to Wall Sensor Overview & Installation

| Ceiling Sensor V2.0

The Ceiling Sensor V2.0 is an Intelligent-Ceiling Temperature and Humidity Sensor (CTH). It adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. It is easily mounted on a ceiling by a threaded bush. The module drop from the ceiling can be adjusted via a set screw. For more information refer to Ceiling Sensor V2.0 Overview and Installation

| Ceiling Sensor V1.0

The Ceiling Sensor V1.0 is also an Intelligent-Ceiling Temperature and Humidity Sensor (CTH). It adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. It is easily mounted on a ceiling by a threaded bush, except it does not have the wiring harness that is supported within the Ceiling Sensor V2.0. This was introduced to V2.0 to help solve the problems faced by V1.0 that were found during installation, which helps support the lengths of one wire cable.

| Flush Mount Sensor

The Flush Mount Sensor is an Intelligent-Flush mount temperature and humidity Sensor (FTH). It adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. It is easily mounted on a wall or metal beam duct by self-drilling screws. Unlike an RTH it does not involve drilling a hole for the mounting or running the wiring behind the surface. For more information refer to Ceiling/Flush Mount/Duct Sensors

| Differential Pressure Sensor

The Differential Pressure sensor extends the sensor capabilities of 75F's controllers. Its use opens up an array of additional applications from flow sensing in VAV boxes to monitoring filter performance in AHUs.

The DPS's compact profile and rugged construction allow it to be mounted on the sides of VAV boxes, hard supports, or rafters. For more information refer to Differential Pressure Sensor (DPS) Overview and Installation

| Duct Sensor V2.0

mceclip6.png

The Duct Sensor V2.0 is an Intelligent-Duct temperature and humidity Sensor (DTH). It adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. It is easily mounted on a duct or VAV box by self-drilling screws. For more information refer to Duct Sensor V2.0 Overview

| Duct Sensor V1.0

mceclip7.png

The Duct Sensor V1.0 is an Intelligent-Duct temperature and humidity Sensor (DTH). It adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. The DTH is easily mounted on an RTU duct by self-drilling screws. For more information refer to Ceiling/Flush Mount/Duct Sensors

| Wired Multi-Sensor

mceclip1.png

The Wired Multi-Sensor is a sensor that brings in additional parameter sensing. Unlike other 75F sensors that detect just temperature and humidity, the wired multi-sensor also detects CO2 and Occupancy. This sensor lies between the HyperSense, which adds local interface control, and the wall sensor, which does not have CO2 and Occupancy detection.  For more information refer to Wired Multi Sensor Overview and Installation

| Need for Different Sensor

All rooms experience different parameters (Temperature, Humidity, Light Intensity, CO2, and Occupancy), and 75F realized that to monitor these specific parameters we would need multiple types of sensors. These sensors can be installed in particular places within a room to help attain better values and control the space more efficiently.

| Need for Advanced Sensor with Similar Capabilities

75F's older sensors that were a part of the original 75F suite of building automation solved just one or two particular use cases within a room, allowing there to be some missed-out use cases. To help solve those missed-out use cases, 75F introduced new features in the advanced versions of our sensors.
