Page 18: Probes Connection
11.1 PROBES CONNECTION The probes shall be mounted with the bulb upwards to prevent damages due to casual liquid infiltration. It is recommended to place the thermostat probe away from air streams to correctly measure the average room temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is formed, far from heaters and from the warmest place during defrost, to prevent premature defrost termination. -

• soft chill • freezing cycle 2. For each phase there are 3 parameters. iS1, (iS 2, iS 3): Set point related to the insert probes that stops the current phase. rS1, (rS2, rS3): set point of the room temperature for each phase. Pd1, (Pd2, Pd3): the maximum duration time for each phase. - Page 29 17.3.1 First phase: “Hard chill”. It is normally used to fast chill hot foods. E.g. from 80°C / 170°F to 20°C / 70°F During “Hard Chill”, both compressor and fan are always on until the rS1 temperature is reached. At this point compressor is turned on end off so as to keep the temperature of the room at the rS1 value.
