The device is designed to alleviate nuisance opening of the low pressure switch by bypassing it for the first 3 minutes of operation. A winter start control maybe used where low evaporator temperatures, or nuisance tripping of low pressure switch maybe encountered. It is not required for low ambient cooling application unless a low pressure switch KAALP0401PUR is added and nuisance tripping is a concern.
