HyperSense is a trimmed version of the HyperStat, which can be used with a SmartNode. It is a HyperStat with just the sensing capabilities, and without the control capabilities. The SmartNode which is a room level controller, with not much sensing capabilities, can accommodate only one sensor to sense temperature and humidity parameters.

The HyperSense which comes with 8 onboard sensors from its predecessor HyperStat, can be used with the SmartNode to provide excellent sensing capabilities, along with the control capabilities of the Smart Node. 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 to the user to change a few parameters which would help achieve user comfort.

| How it Works

The HyperSense senses various parameter values in the room and serves it to the SmartNode, which in turn not only uses them in the algorithm to provide various required conditioning, but also serves it to the CCU, to be served to the cloud for visualizing in the applications.

This avoids the need to wire more than a few different sensors to the SmartNode to sense various parameter in the room. It also acts as a wired user interface to Smart Node running a DAB or Lighting Profiles.

| Features

  • Inbuilt sensors to monitor temperature, relative humidity, Ambient light, Occupancy, CO2, VOC and PM2.5(optional)
  • Power from RS485 4-wire cable harness from Smart Node 
  • Consumes 1.2W of power. 
  • Both mechanical and touch buttons for user interaction 
  • Has a bigger 2.8" display for better user experience

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

| Mounting

Video Place holder

| 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 subbase 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 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

mceclip5.png

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

At Position 1:

mceclip1.png

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

 

Airflow Temperature Sensing

7.png

The Airflow Temperature Sensor, which is inserted into the airflow duct as show above, is wired to the thermistor pins of the HyperSense. Based on the Airflow a resistance is generated, and the resistance generated is communicated to the HyperSense in Ohms. The HyperSense looks up a preconfigured table for a corresponding temperature value and uses the same for the altering the control sequences.

 

Door & Window Sensing

8.png

A Door/Window Sensor as shown in the above image is wired to the thermistor pins of the HyperSense Based on opening of the door or the window a resistance is generated, and the resistance generated is communicated to the HyperSense in Ohms. The HyperSense looks up for a preconfigure action set up for a door opening shuts off the conditioning inorder to avoid losses, and once the door is closed again starts the conditioning.

 

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

 

Keycard Sensing

The Analog input can be configured for various type of sensing, of which the Key Card Sensing one of most attractive introductions.

A Keycard Sensor as shown in the above image is wired to the Analog In pin of the HyperSense. Based on the insertion of the keycard, a voltage value is generated and the same is displayed in the HyperSense. The HyperSense uses the generated voltage values to trigger the occupancy-based energy sequences via SmartNode. 

Current Sensing

The Analog Input in the HyperSense can also be configured for current sensing at times. A Current Transformer as shown above is wired to the Analog In pin of the HyperSense. It works on the principle of the faradays law (a current carrying conductor induces a magnetic field around it), based on the number of turns of the magnetic fields a voltage is generated and communicated to the Analog in of HyperSense, the HyperSense looks up in the predefined table for the actual Voltage that is generated based on the scaled voltage. This is used to calculate the current consumed for the circuit.

 

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

 

At Position 3:

mceclip3.png

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 Wire Screw Connector

1.jpg

This uses a 4 pin Molex connector at one end and a 4 wire, screw connector at the other end, and can be used with length 4-wire protocol cable, based on the distance at which the SmartNode is from the HyperSense. You can simply twist the four wires and insert them into the screw slots provided for connection. 

At Position 3:

mceclip4.png

At this position, the HyperSense is provided with low power sensor bus socket which supports 3-wire protocol sensor connections. This hosts the wiring for additional sensor requirements

The 75F supports with 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 a 3-wire protocol and accommodates 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 is a jumper and how it is used.
