Heating and Ventilating Control

Three heating and ventilating options are available to provide proper tempering and fulfill varying requirements for fresh outdoor air. In all cases, heating and cooling functions are controlled by a Greenheck room thermostat or a DDC system (by others).

HV1: 0%-30% Minimum Outdoor Air

HV1 is the most common among heating and ventilating units, allowing you to set the minimum outdoor air volume between 0 and 30% of the total supply air volume. With the relatively low percentage of outdoor air, mixed air temperatures are mild and stable.

1-stage heating and/or cooling is recommended. (2-stage or electronic modulation is optional).

HV2: 30%-75% Minimum Outdoor Air

The HV2 option is required when the minimum outdoor air volume exceeds 30% of the total supply air volume. With higher outdoor air volumes, mixed air temperatures

can vary greatly. Accordingly, 2-stage heating and/or cooling is recommended. Also, an airstream override thermostat is standard with HV2 to prevent cold air discharge (below 55˚ F) when the thermostat is satisfied. (electronic

modulation is optional).

HV3: 100% Return Air

The HV3 option is available when no outdoor air is needed. With relatively stable return air conditions, 1-stage heating and/or cooling is strongly recommended. (2-stage or electronic modulation is optional).

Thermostat Options

Basic bimetal thermostats with mercury switches or fully programmable electronic thermostats are available as part of your IGX-HV system. Match your heating, cooling, staging, and operational requirements to the appropriate thermostat.

TC1: 1-Stage Heating / Cooling

TC4: Programmable

TC1 is a coiled bimetal thermostat used for single-stage heating, cooling or heating-cooling systems.

TC2: 2-Stage Heating

TC2 is a coiled bimetal thermostat used for 2-stage heating systems.

TC3: 2-Stage Heating / 2-Stage Cooling

TC3 is a coiled bimetal thermostat used for 2-stage heating, cooling or heating- cooling systems. It includes an adjustable heat anticipator, stops, and a locking cover.

TC4 has full seven-day program capability. The thermostat can be set for four times and eight temperature settings each day of the week. It can control up to two stages of heating and two stages of cooling.

TC5: Deluxe Programmable

TC5 has full seven-day program capability. The thermostat can be set for two occupied and two unoccupied times with adjustable temperature settings for each day of the week. It can control up to three stages of heating and two

stages of cooling. The Intelligent Fan™ feature energizes the fan continuously during occupied mode and intermittently with a call for heating or cooling in unoccupied mode.

IGX-HV specifications

The Greenheck Fan IGX-HV is a groundbreaking product tailored for high-volume, low-pressure ventilation applications. Engineered for optimal performance, the IGX-HV series stands out in the market due to its design and technology, which are focused on delivering efficient airflow solutions while ensuring energy conservation.

One of the key features of the IGX-HV is its robust construction, which includes a galvanized steel housing that offers durability and resistance to corrosion. This is particularly important in environments where the fan may be exposed to harsh conditions. The fan is designed with an integrated mounting system that simplifies installation and provides long-term reliability.

In terms of performance, the IGX-HV is equipped with Greenheck's innovative EHX™ motor technology, which enhances efficiency and reduces energy consumption. This permanent split capacitor motor is designed to operate at optimal levels, contributing to lower operational costs. Additionally, the fan is available in a range of sizes and configurations, catering to the diverse needs of commercial and industrial applications.

The IGX-HV also features a backward-inclined wheel that contributes to its high efficiency and reduced noise levels. This design not only increases performance but also minimizes turbulence, creating a quieter operating environment. The fan’s aerodynamic profile ensures that it can handle large volumes of air, making it ideal for use in spaces such as warehouses, manufacturing facilities, and large retail environments.

Another notable characteristic of the Greenheck IGX-HV is its user-friendly interface, which provides easy access to control and monitoring systems. This allows facility managers to easily adjust settings and track performance metrics, streamlining maintenance processes and enhancing operational efficiency.

Moreover, the IGX-HV complies with the latest energy efficiency standards, making it a sustainable choice for businesses looking to minimize their environmental impact. By integrating advanced technologies, such as variable speed drives, the fan can adjust its performance based on the actual demand, further optimizing energy usage.

In summary, the Greenheck Fan IGX-HV is a versatile and efficient solution for high-volume ventilation needs. Its combination of durable construction, advanced motor technologies, and user-friendly features makes it an excellent choice for a variety of applications, positioning it as a leader in the ventilation industry. Whether for industrial or commercial use, the IGX-HV meets the demands of modern ventilation systems while emphasizing energy efficiency and performance.
