HelioNode

The HelioNode is an advanced IoT room controller created for temperature, IAQ, and lighting control in office buildings. It is easy to install in the ceiling and contains within it all the sensors for measuring temperature, humidity, CO2, occupancy, and light levels which eliminates wiring runs or additional integration of sensors.

For more information on HelioNode refer to HelioNode Installation &  HelioNode UI Navigation.

Occupancy and Temperature Node (OTN)

Occupancy and Temperature Node is a device, tailormade for those customers who need micro zone level controls that can override the existing schedules. This comes in handy in cases where there is dynamic occupancy in a space like:

• A restaurant where occupancy varies from day to day and time to time.
• Work environments post-COVID-19, where the employee strength is cycled predicting which desks will be occupied and which will not, is a new requirement to handle energy efficiency.

For more information on Battery Powered Occupancy Sensors (BPOS) refer to Occupancy & Temperature Node- Temperature Influencing

Stats

Stats is another type of terminal device that is used to control and monitor the terminal level equipment such as the fan coil units, heat pump units, etc.

75F supports two types of stats.

HyperStat

The HyperStat, conceived as a successor to the original SmartStat, has evolved with 8 onboard sensors, providing the advanced capability of the thermostat, humidistat, and IAQ sensing station with both modulating and staged equipment control. HyperStat provides monitoring and control of a wide variety of HVAC standalone equipment through its various relay stages or modulating analog outputs.

The HyperStat is a Wall mount product, and the design is done thoughtfully to make sure that the product blends into most of the commercial spaces while still giving a fresh and contemporary feel compared to dated building control interfaces.

For more information on HyperStat, refer to HyperStat Installation & HyperStat UI.

Connect Module

The Connect Module is a versatile and feature-packed device that connects to various devices seamlessly using Modbus/BACnet in a building automation system. It is designed to interface with a variety of input and output devices, making it ideal for use in a wide range of applications.

MyStat

MyStat is a thermostat which works with most HVAC systems that use standalone heating/cooling and uses industry standard connections to facilitate the control of these appliances.

It can be used to control single stage Heating/Cooling with Fan or upto 3 stages of only cooling or heating using the four onboard relays. It works on the 75F proprietary RF communication which helps in seamless integration with existing 75F solution. This device can also be run in a standalone mode which can be programmed using a CCU.

 

Sensors

Sensors are devices used to sense and translate various parameters in the building like the temperature, humidity, light levels, pressure, etc, They reach every nook and corner of the building to sense information, and communicate it back to the terminal devices such as the nodes and stats.

For more information on sensors, refer to Intro to the 75F Family of Sensors

Based on the location, it can be in the building where the 75F supports various types of sensors.

• HyperSense
• Wired Multi Sensor
• Wireless Multi Sensor
• Differential Pressure Sensor
• Universal Sensor Platform
• Flush Mount Sensor
• Ceiling Sensor
• Wall Sensor
• Wireless Door Sensor

HyperSense

This product is built as a successor to the SmartSense from 75F. The product caters to use cases where a highly capable remote interface is desired for Smart Nodes operating in the plenum. HyperSense is part of 75F's vertically-integrated suite of intelligent building solutions delivering multi-mode sensing, remote monitoring, and individual zone control for the comfort and productivity of building occupants.

The HyperSense is a Wall mount product, and the design is done thoughtfully to make sure that the product blends into most of the commercial spaces while still giving a fresh and contemporary feel compared to dated Building control interfaces.

 

Wired Multi Sensor

A sensor that augments the SmartNode to add full Title 24 compliance. In addition to comfort (temperature/humidity), the SmartNode has capabilities for /IAQ (CO2) and occupancy-based energy sequences. In addition to adding this functionality, this would be a good platform to test out newer CO2 sensors and occupancy detection mechanisms.

This sensor lies between the HyperSense which adds local interface control and the wall sensor which does not have CO2 and occupancy detection. The form factor would be much smaller than the HyperSense as is the price point.

 

Wireless Multi Sensor

As spaces get larger, traditional wired wall-mounted sensors become costly and complex to install, with wire runs reaching up to 100 feet. Our innovative Wireless Multi Sensor eliminates the need for expensive, plenum-rated cabling and drastically reduces installation labor.

 

Designed to fit modern needs, this sensor not only monitors temperature and humidity but also detects occupancy, ensuring comfort where it’s needed most—all while optimizing power savings with the range of sensor inputs it offers. With a battery life of over 5* years, it’s built to last in large spaces without constant maintenance.

Differential Pressure  Sensor (DPS)

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 on Differential Pressure Sensors, refer to the  Differential Pressure Sensor (DPS) Installation

Universal Sensor Platform

The Universal Sensor Platform1 is engineered for maximum flexibility, operating effortlessly on battery power or connecting via a 2-wire PoR bus to a Node or stat. This streamlined communication protocol drastically cuts wiring costs and installation effort.

Plus, with built-in Bluetooth connectivity when running on battery, it delivers unparalleled mobility—making deployment faster, easier, and more versatile than ever.

 

Flush Mount Sensor

The Intelligent-Flush mount temperature and humidity Sensor (FTH) adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. The FTH 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.

The FTH uses a proprietary 1-wire protocol to communicate with a master device such as a SmartNode- OAO.

Ceiling Sensor

The Intelligent-Ceiling Temperature and Humidity Sensor (CTH) adds a high precision temperature and humidity sensor that is pre-calibrated from the factory. The CTH is easily mounted on a ceiling by a threaded bush. The module drop from the ceiling can be adjusted via a set screw.

The CTH uses a proprietary Sensor bus to communicate with a master device such as an HIA or SmartNode. In principle, the CTH can be daisy-chained with other sensors on the 1-wire bus to provide an extensible sensor network.

Wall Sensor

The Remote Temperature and Humidity Sensor (RTH) or in simple called the Wall Sensor adds a high-precision temperature and humidity sensor that is pre-calibrated from the factory. The RTH is easily mounted on a wall by a single toggle bolt.

The Wall Sensor uses a proprietary 1-wire protocol to communicate with a master device such as an HIA or SmartNode. In principle, the Wall Sesnor can be daisy-chained with other sensors on the 1-wire bus to provide an extensible sensor network.

Wireless Door Sensor

This magnetic door sensor features an ultra-low power chipset from the nRF52 series and BLE 5.0 technology. It consists of two parts: the sensor body and the magnetic part, both equipped with double-sided adhesive for easy installation on doors, windows, and roll up blinds to detect opening and closing. Designed for remote monitoring of door/window activities, the sensor automatically sends notifications to a node or stat when the door is opened, allowing users to check door opening records on either the Hardware UI or portals.
