Program PR1: temperature-based cooling
Program for product cooling by positive temperature. Cooling ends when the core of the
product reaches temperature At1. A maximum safety time is set on parameter Ab1. When
cooling is over the controller automatically goes to storage mode with the ST1 setting. ST1
also has the function of controlling the compressor, which stops if the room temperature
reaches temperature ST1-r1. The compressor is reactivated on reaching temperature ST1.
