AIIR Products, a US-based developer of heating and cooling systems, will integrate a customised version of Copeland’s Verdant VX4 thermostat into its products.
The agreement combines AIIR’s machine-learning HVAC equipment with Copeland’s room-control technology. Copeland manufactures compressors and controls for heating, cooling and refrigeration systems.
The VX4 will serve as the sole user interface for AIIR’s classic controls mode. It will also be accessible via the AIIR User App, allowing residents to adjust temperature, humidity and airflow remotely.
Smart controls for multifamily and hospitality projects
AIIR expects the arrangement to simplify specifying and installing its equipment in new developments and upgrades to existing buildings.
It said the Verdant platform is used across more than 11,000 properties. AIIR believes that using a thermostat already known to hospitality operators could help developers secure approval for projects subject to hotel-brand standards.
The VX4 can be installed using wired or wireless connections. The company estimated deployment time at about 10 minutes but did not provide further details on how they calculated that estimate.
Copeland introduced the thermostat in 2024 for commercial and multifamily properties in North America and Europe. Its occupancy sensor detects motion and body heat to determine whether a room is in use. When the room is vacant, the thermostat can adjust the temperature setting to reduce heating or cooling runtime.
Copeland thermostat joins existing AIIR system
AIIR’s current Intelligent HVAC system has been on the market since late 2024. According to the company, the compact, ductless unit fits into a 17-inch-wide space between wall studs, reducing the need for ductwork or a separate HVAC cupboard.
AIIR also presents the equipment as an alternative to a packaged terminal air conditioner (PTAC), a self-contained heating and cooling unit often installed beneath a hotel room window.
Onboard sensors collect data on room conditions and occupancy. Machine-learning software uses this data, together with occupants’ settings and usage patterns, to adjust the system’s operation.
The link with Verdant also enables the equipment to connect to energy management systems (EMS) and building management systems (BMS). An EMS monitors and controls energy consumption, while a BMS gives property operators central oversight of services such as heating, cooling, and ventilation.
One model in the AIIR range received AHRI certification in 2025. The certification confirms the equipment’s published performance ratings but does not cover the new thermostat arrangement.
The certified model has a cooling capacity of 8,000 British thermal units per hour (BTU/h) and a heating capacity of 8,600 BTU/h at 47°F (about 8.3°C). BTU/h measures the amount of heat that heating or cooling equipment can add or remove per hour.
The unit recorded a seasonal energy efficiency ratio (SEER2) of 17 and a heating seasonal performance factor (HSPF2) of 8.0. SEER2 measures seasonal cooling efficiency in the US, while HSPF2 measures a heat pump’s heating efficiency.
Savings figures come from previous Verdant installations
AIIR said the Verdant VX4 had delivered HVAC energy savings of 15% to 20% in prior hospitality and multifamily installations. It did not report results from any property using the thermostat with AIIR equipment, though.
The company also referred to California’s Title 24 Building Energy Efficiency Standards and New York City’s Local Law 97. Title 24 sets energy-efficiency requirements for buildings in California, while Local Law 97 limits carbon emissions from many large buildings in New York City. AIIR did not state that the combined system had been certified as complying with either regulation.
