HyperSense is a trimmed version of HyperStat. It is used with a SmartNode. It is a HyperStat with just the sensing capabilities and without the control capabilities. The SmartNode, a room-level controller with little sensing capabilities, can accommodate only one sensor to sense temperature and humidity parameters.

Note: The Hypersense cannot be used with HelioNode.

The HyperSense comes with 7 onboard sensors and 1 optional sensor from its predecessor HyperStat. It can be used with the SmartNode to provide excellent sensing capabilities, along with the control capabilities of the SmartNode. It can sense and deliver various parameter values in a room to the SmartNode, with which the SmartNode could vary the controls the algorithm can provide.

The SmartNodes are usually installed in the plenum in the room, making it difficult for the occupants to access the SmartNode screens for any information. With the introduction of HyperSense, this problem could also be solved.

HyperSense also provides a means for the user to change various parameters, which would help achieve user comfort.

| How it Works

The HyperSense senses various parameter values in the room and serves them to the SmartNode. The SmartNode in turn uses them in the algorithm to provide conditioning and serves it to the CCU. They can be visualized over the Cloud.

This avoids the need to wire more than a few different sensors to the SmartNode to sense various parameters in the room. It also acts as a wired user interface to SmartNode running a DAB or VAV profile.

| Features

  • Inbuilt sensors to monitor temperature, relative humidity, Ambient light, Occupancy, CO2, VOC, Sound, and PM2.5(optional)
  • Power from RS485 4-wire cable harness from SmartNode 
  • Consumes 1.2W of power. 
  • Both mechanical and touch buttons for user interaction 
  • Has a bigger 2.8" display for a better user experience 
  • The occupancy detection angle is 4m with a 110-degree angle.

| Wiring



Both powering and communication are done through the 4-wire cable harnessed to the RS 485 port in the HyperSense, and hence wiring effort is minimized. 

| Mounting

| Mounting Instructions

  • Mount the HyperSense back (Subbase).
  • Level the HyperSense in the desired mounting location.
  • Mark the holes on each side.
  • Drill a 5/16” hole.
  • Insert the provided anchors.
  • Screw the sub base into place using the provided #6-32 1” screws
  • Place the HyperStat Interface-HyperSense PCB and the back plate (only if the gang box is fixed vertically) on the gang box such that the back plate covers the gang box and fix these two items to the wall gang box with the PHP screws provided in the box.
  • Now align the HyperStat main to lock onto the HyperStat Interface- HyperSense PCB.
  • Use the Allen head screws to make this entire setup tamper-proof.
  • Rubber covers 1 and 2 must be fixed to cover the programming pins.

| Wiring Pin Details


The HyperSense is provided with several pins for wiring the HVAC inputs, below are the details of the same.

At Position 1:


Pin Details Purpose/Usage
TH1 Hosts the power wire, for the resistance-based parameters sensing example Airflow Temperature Sensor, where sensing of the parameter happens by a foreseeable and precise variation in resistance.
TH2 Hosts the power wire, for the resistance-based parameters sensing example Door/Window Sensor, where sensing of the parameter happens by a foreseeable and precise variation in resistance.


Pin Details Purpose/Usage
AI1 Hosts the power wire connection for analog-controlled input for example (Keycard Sensor/another Door/Window Sensor/ Currents TX (0-10Amps/0-20Amps/0-50 Amps))
AI2 Hosts the power wire connection for analog-controlled input for example (Keycard Sensor/another Door/Window Sensor/ Currents TX (0-10Amps/0-20Amps/0-50 Amps))


Pin Details Purpose/Usage
Grounds Hosts the ground wires for the Thermistors & Analog Ins 


At Position 2:


At this position, the HyperSense is provided with RS 485 socket which supports a 4-wire protocol connector. This hosts the wiring for powering the HyperSense from the SmartNode, which also aids communication

The 75F supports a wiring harness to meet this wiring connection between the SmartNode and the HyperSense

4 Pin to 4 Pin Cable


This uses two 4-pin Molex connectors at both ends which gets connected to SmartNode from the HyperSense. 

At Position 3:


At this position, the HyperSense is provided with a low-power sensor bus socket that supports sensor bus connections. This hosts the wiring for additional sensor requirements

The 75F supports a type of wiring harness to meet sensor connections.

3 Pin to 3 Pin Cable


This uses a 3-pin Molex connector at both ends and can be used with sensors that use sensor bus connections and accommodate a Molex connector at termination. 

| Jumper Settings

Jumpers are electronic components that are used to short two points to achieve a certain operation.

Below is an illustration of what a jumper is and how it is used.


The HyperSense hardware of 75F uses Two types of jumpers at two places for two different operations.


Position 1:

In this position,

Short if the Hypersense conventional device is the last device on the RS485 line.  

If it is not shorted, there is no terminal resistance, and the device can be used as one of the multi-drop connections.

Position 2:

In this position, 2 Jumpers are used to switch between the Digital and Analog types of inputs.

It should be noted that shorting this jumper position for either A1 or A2 makes the Hypersense ready to receive external digital input through AIn1 and AIn2 terminal connectors. Open the jumpers if analog voltage inputs are to be sensed through the Ain1 and Ain2 terminals.


| Regular Update to CCU 

When Hypersense is used with SmartNode the parameters sent to the CCU would vary based on the following

The SmartNode can use just the HyperSense or a combination of the OWI sensor and HyperSense.

Under such circumstances, the regular update that is sent to CCU would differ accordingly.

The table below provides the information about the same.

SmartNode+ HyperSense (RS485) SmartNode+ HyperSense (RS485) +OWI




Temperature - OWI
Humidity - OWI
Occupancy - OWI
Pressure - OWI / Sound - RS485
(with a pressure sensor in the bus, pressure takes precedence over the sound)

VOC - RS485

PM2.5/10 - RS485/ Light - RS485 (if particulate matters detected PM2.5 takes precedence over the light)

Note: As a part of a regular update only six other parameters over and above the temperature can be sent to the CCU. Hence based on the type of sensors used in the bus, the parameters for the update take precedence/ ignored.
