Introduction: Redefining Comfort and Energy Efficiency in Modern Buildings
In commercial buildings and high-end residential projects, temperature consistency has become a critical measure of space quality. Traditional single-point thermostat systems fail to address zone temperature variations caused by solar exposure, space layout, and equipment heat loads. Multi-zone smart thermostat systems with remote sensors are emerging as the preferred solution for HVAC professionals across North America.
