Program PR4: time-based cooling
Program for product cooling by time. Cooling ends when the maximum time Ab4 has
expired. When cooling is over the controller automatically goes to storage mode with the
ST4 setting. ST4 also has the function of regulating the compressor, which stops if room
temperature reaches temperature ST4-r1. The compressor is reactivated on reaching
temperature ST4.
Program PR5: time-based freezing
Product freezing program by time. Freezing ends when maximum time Ab5 has expired.
When freezing is over the controller automatically goes to storage mode with the ST5
setting. The compressor works continuously.
