Auto-Restart is a convenient feature that allows your HVAC system to automatically resume its previous settings after a power outage. Instead of having to manually turn on your 2-Zone 18,000 BTU R454B system, it remembers the mode, temperature, and fan speed. This is a critical feature for vacation homes, server rooms, or any location where the "End-User" isn't always present. It ensures that your Single-Zone unit continues to protect your home from humidity even if the power flickers. All OLMO Multi-Zone and PTAC units include this "Smart Home" logic as a standard. It prevents the frustration of coming home to a hot house after a brief summer storm. This feature is built into the internal control board and requires no additional Accessories. It is another way we provide a "worry-free" comfort experience for our customers.
