HyperSense Overview & Installation

6 Minute Read

| Overview

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

The HyperSense comes with 8 onboard sensors from its predecessor HyperStat. It can be used with the SmarNode to provide excellent sensing capabilities, along with the control capabilities of the SmarNode. It can sense and deliver various parameter values in a room to the SmarNode, with which the SmarNode 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 SmarNode 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 SmarNode, 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 SmarNode to sense various parameters in the room. It also acts as a wired user interface to SmarNode running a VVT-C 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 SmarNode 
• Consumes 1.2W of power. 
• Both mechanical and touch buttons for user interaction 
• Has a bigger 2.8" display for a better user experience 

| 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 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

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

 

Door & Window Sensing

A Door/Window Sensor as shown in the above image is wired to the thermistor pins of the HyperSense Based on the 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 ordered 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 types of senses, of which the Key Card Sensing is one of the 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 SmarNode. 

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 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 SmarNode, which also aids communication

The Carrier supports a wiring harness to meet this wiring connection between the SmarNode and the HyperSense

4 Pin to 4 Pin Cable

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

At Position 3:

At this position, the HyperSense is provided with a low-power sensor bus socket that supports 3-wire communicating sensors for temperature averaging, an alternate zone temperature source, and/or for additional occupancy detection. 

The Carrier 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 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.

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

Position 1:

At 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:

At 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 Ain1 and Ain2 terminals.
