| Hardware devices

The products and the actual physical devices that are a part of the Carrier BMS are also addressed as the hardware. The Carrier provides a portfolio of hardware devices.

The devices belong to four major categories:

  • Sensors
  • Nodes
  • Stats
  • CCU’s

| Overview of Carrier Product hardware

CCU's

mceclip2.png

CCU is a Carrier hardware device that is used to control and monitor the building/ system level equipment (AHU / RTU). It in this CCU the Carrier software Renatus is installed, and system-level profiles are configured to selectively control equipment.

For more information on CCU refer to Central Control Unit Installation & Central Control Unit (CCU) Navigation and Indicators.

Nodes

Nodes are terminal devices used to control and monitor terminal-level equipment like dampers and actuators.

Carrier support two types of nodes.

SmarNode

The SmarNode is a room equipment controller. It is envisaged as a general-purpose device that controls dampers for airflow and a couple of lights. It operates off 24v and has inputs for measuring room and airflow temperatures.

For more information on SmartNodes refer to SmarNode Installation & SmarNode Navigation and Indicators.

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.

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 Covid19 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.

Carrier supports two types of stats.

Smart Stat

The SmartStat is a combination of an ITM and SmartStat daughter board that adds physical control capabilities to the ITM. The SmartStat daughter board is a slave device that connects to the ITM over 4 wire RS-485 interface.

The SmartStat adds occupancy detection in addition to temperature, humidity, and light measurement on the ITM. It also has an additional button that allows local user control for functions like fan speed depending on the profile. In addition, the SmartStat can be ordered with a CO2 sensor to add room measurement for places like conference rooms.

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.

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 Carrier Family of Sensors

Based on the location it can be in the building the Carrier support various type of sensor.

Differential Pressure  Sensor (DPS)

The Differential Pressure sensor extends the sensor capabilities of Carrier'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.

Carrier also supports a portfolio of 3rd party hardware below is a summary of the same.
