Carrier KAAWS0101AAA Control 321702-401 relying entirely on the vapor-pressureThe Carrier KAAWS0101AAA Winter Start Control is a critical field installed accessory designed to prevent nuisance tripping of the low pressure switch during cold weather startups. This 24VAC time delay relay (TDR) bypasses the low pressure circuit for the first 3 minutes of operation, allowing system pressures to stabilize when evaporator temperatures are low. It is an essential component for split system air conditioners utilizing low ambient
