The new-generation Infinityâ„¢ System is the first HVAC system to use a single control to integrate and manage all six comfort functions: temperature, humidity, airflow, ventilation, indoor air quality and zoning, says the company. With the Infinity Control, the system provides longer heating and cooling cycles at lower fan speeds for energy savings and more consistent temperatures throughout the house, states the manufacturer. The control is easy to program, has a distinctive, easy-to-read, large, backlit display, and communication capabilities, such as advising when it's time for regular maintenance and filter changes, the company says. Infinity System options include zoning, humidifiers, ventilation systems, air cleaners, and ultraviolet germicidal lamps. Up to eight zones can be managed by the system.
