Profiles / Applications Overview

10 Minute Read

| Profiles/Applications

Profile/ Application is a predefined configuration generated from the Intelligence embedded algorithm, that can be preset based on available control, signal inputs, and outputs that drive the hardware products to act accordingly.

Profiles are based on the main HVAC equipment used and the type of conditioning required in the building.

There are two types of profiles supported by the 75F BMS.

System Profile: A profile that controls the system or building-level equipment.
Terminal Profile: A profile that controls the terminal or zone-level equipment.

| Overview of 75F Profiles

Under the above-mentioned types and based on the conditioning required and the terminal devices used the profiles summary supported by 75F BMS is as follows.

System Profile

The system profile or application is the one that is configured in the CCU that determines the type of control for the system-level equipment such as Air Handling Units (AHUs) and Roof Top Units (RTUs).

75F support three categories of control for the system-level equipment.

Dynamic Airflow Balancing (DAB)

75F Dynamic Airflow Balancing (DAB) is a proactive zone control system that remotely monitors and controls conditions in individual spaces for superior comfort and efficiency. Predictive machine learning algorithms optimize heating and cooling capacity by redirecting conditioned air to the spaces that need it most.

It uses SmartNodes connected to zone-level dampers to control the airflow based on the individual zone-level requirement. Based on the outside temperature during the day, different zones would expect different kinds of conditioning during different times of the day. To satisfy this condition, Dynamic Airflow Balancing (DAB) uses an algorithm to provide a dynamic airflow to the zones.

Under the category Dynamic Airflow Balancing (DAB) system profile 75F support five types of system profile.

Staged RTU with VFD

Staged RTU with VFD is a profile similar to the Staged RTU but uses a variable frequency drive (VFD) to control the fan speed during the staged conditioning.

For more information refer to DAB Staged RTU w/ VFD Fan - Wiring/Configuration

Modulating AHU

Modulating AHU is a profile where the input from the Air handler Unit (AHU), system-level equipment, is controlled using a modulating analog signal of 0Vdc to 10 Vdc to provide the required conditioning.

For more information refer to DAB Fully Modulating AHU - Wiring/Configuration

DAB Advanced Hybrid AHU v2 with Advanced AHU Controls

With configurable advanced control sequences can cut the amount of time required to commission such AHUs to a large extent. The already available IO ports in the CCU is an added advantage. With the CCU itself, we can perform the advanced AHU functions without adding additional hardware, but the profile also is provisioned to add up to 2 connect modules for any extra IO that might be needed for the AHU for control or monitoring purposes.

Modulating AHU with DCWB

Modulating AHU with DCWB is a profile that not only controls the air side by, controlling the input from the Air handler Unit (AHU) which is system-level equipment, but is controlled using a modulating analog signal of 0Vdc to 10 Vdc to provide the required conditioning, it also controls the chilled water supply required for the conditioning using the concepts of Dynamic Chilled Water Balancing.

For more information refer to DAB Modulating AHU with DCWB

DAB External AHU Controller

DAB External AHU Controller is a system-level profile in the 75F system. The profile is used with an external AHU (BACnet/Modbus-based).

The control of these complex external devices, can not only be based on zone load but also requires control triggers based on the Supply Air Temperature (SAT), Duct Static Pressure (DSP), and zone load-based control.

Unlike the other system profiles, the DAB External AHU controller profile does not control the external equipment directly, but indirectly the CCU contributes to the following.

Monitor, and aggregate for visualizations in portals.
Apply algorithms to calculate setpoints.
Communicate the calculated setpoint to the External device for control actions.

Variable Airflow Volume (VAV)

75F Variable Airflow Volume is a concept of varying the airflow from the system-level equipment based on the needs of the zones or the spaces that are conditioned.

It uses SmartNodes connected to zone-level dampers to control the airflow based on the individual zone-level requirement. regardless of the outside temperature or condition.

Under the category Variable Airflow Volume (VAV) system profile 75F support six types of system profile.

Staged RTU with VFD

Staged RTU with VFD is a profile similar to the Staged RTU but uses a variable frequency drive (VFD) to control the fan speed during the staged conditioning.

The heat pump unit consists of the compressor with refrigerant, a reversing valve, a fan, and Auxiliary heating equipment that provides the required conditioning.

For more information refer to HyperStat Heat Pump Unit (HPU)

2 Pipe Fan Coil Unit (2PFCU)

As the name suggests, a 2 Pipe Fan Coil Unit (2PFCU) comprises 2 pipes, allowing water supply with a fan that runs air over it. The air is further conditioned by the running water. The thermostat only has control over whether to turn on the fan and at what speed. The building's central plant determines whether the pipes are getting hot or cold water. As such, turning on the fan when the building is providing hot water and the current temperature is above the desired temperature is counterproductive.

A coil fed by 1 pair of supply pipes provides heating or cooling. The correct mode is based on sensing the supply water temperature.

For more information refer to HyperStat 2 Pipe Fan Coil Unit (2PFCU)

4 Pipe Fan Coil Unit (4PFCU)

A 4-Pipe Fan Coil Unit (4PFCU) uses four pipes, two for chilled water and two for hot water, along with a fan that circulates room air across the coil. As air passes over the coil, it is conditioned by the water flowing through it.

In a typical setup, the thermostat controls only the fan operation and fan speed. The decision to supply hot or chilled water is made by the building’s central plant, not the local thermostat. As a result, the fan may run even when the available water temperature does not support the desired room condition, for example, running the fan while hot water is supplied when the space already requires cooling, which is inefficient and counterproductive.

Each coil is served by a pair of supply and return pipes dedicated to either heating or cooling. The unit determines the appropriate operating mode by sensing the supply water temperature, enabling it to activate the correct coil and avoid unnecessary fan operation when the available water cannot meet the room’s demand.

2Pipe Unit Ventilator Economizer

A Unit Ventilator is a self-contained HVAC (Heating, Ventilation, and Air Conditioning) device typically installed along the exterior wall of a room, such as a classroom, office, or hotel room. Its main job is to provide heating, cooling, and ventilation for a single Space.

The 2-Pipe Unit Ventilator profile extends 75F's out-of-the-box smart control capabilities to legacy unit ventilators—making them more intelligent, improving comfort, and enhancing energy efficiency for customers.

Built on the Hyperstat Split architecture, the solution uses the Hyperlight for standalone algorithm execution, communicating over RF to the CCU and via a two-wire PR connection to the Connect Module, which then interfaces with the unit ventilator. The profiles offer flexible configuration options—such as fan speeds, damper control, heating stages, water valves, and universal inputs—including a mandatory supply-water-temperature input for mode determination. The profile is fully configurable based on whether control is through a face-and-bypass damper or a modulating valve.
