| Overview

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

The 75F in its vison towards energy savings and Occupant comfort, really stands out in its capability of micro zoning and room level controls. That being said 75F kept adding a number of sensors that would help meet the demands for the vision, to provide an excellent room level control and comfort.

Below are the sensors that 75F provides for room level controls.

  • 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 screws. 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 did not have the wiring harness supported with in V2.0, which was brought in, to solve the problems to face by the V1.0 during installation, to support the lengths of one wire cables.

| 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 a 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 sides of VAV boxes, hard supports or rafters. For more information refer 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 the additional parameter sensing. Over and above the temperature and humidity it can sense 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 parts of the room do not experience the same levels of parameters (Temperature, Humidity, Light Intensity, CO2 and Occupancy) and to make sure what the room experiences to the nitty-gritty, 75F has introduced a sensor that can be installed in a particular place and senses the values for the room controlled to act upon.

| Need for Advanced Sensor with Similar Capabilities

The older sensors which were a part of the 75F suite of building automation, solved just one or two use cases in a room, but not all use cases in the room. inorder to solve for those missed out use cases one or more features were introduced in the advanced versions.
