The auto-restart function is a critical convenience feature that ensures your HVAC system automatically powers back on to its previous settings after a power outage. In regions with frequent summer storms or unstable power grids, this prevents the home from overheating while you are away. This technology is standard across our Cooper&Hunter and OLMO collections. It is especially vital for server rooms or vacation rentals where manual intervention isn't always possible. By preserving your temperature and fan speed settings, it ensures that your multi-zone wall mounts resume operation the moment power is restored. This "set-and-forget" capability is a hallmark of our great deals and more.
