Operating Limits & Bivalent PointTOL = manufacturer-declared minimum operating temperature (often conservative — actual capability may be lower). Tbiv = outdoor temperature below which the heat pump alone can no longer cover its rated heating output, meaning supplemental heating may be needed. More
