pushed).

11. HOW A CYCLE IS DONE.

1.
Every programmable cycle Cy1, Cy2, Cy3 or Cy4 can be divided into up to 3 phases usually called:
hard chill
soft chill
freezing cycle
2.
For each phase there are 3 parameters:
iS1 (iS2, iS3): 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.
Hds: set point of the hold phase at the end of the whole cycle.
There are also 3 parameters: CYS to decide the kinf of cycle, by temperature or by time, and other two
related to the defrost. These are dbC (defrost before cycle) and dbH (defrost before holding, at the end of
the cycle).
11.1 CONFIGURABLE CYCLE PARAMETERS
CYS Cycle setting: tEP=by temperature. The cycle is done according to the rEM parameter. tiM=timed
cycle, based on the Pd1, Pd2, Pd3 parameters.
dbc Defrost before the cycle: n; Y.
iS1 Insert Probe Set point: (-50 to 50, res. 1°C or 1°F) when the temperature measured by the three insert
probes reaches this value the first phase is ended.
rS1 Room probe Set point for the first phase: (-50 to 50, res. 1°C or 1°F) it prevents temperature from
reaching a too low value during the hard cycle.
Pd1 Maximum time for first phase: OFF to 4h00min, res. 10 min.
iS2 Insert probe set point: (-50 to 50, res. 1°C or 1°F) when the temperature measured by the three insert
probes reaches this value the second phase is ended.
rS2 Room probe Set point: (-50 to 50, res. 1°C or 1°F) for the second phase: it prevents temperature from
reaching a too low value during the second phase.
Pd2 Maximum time for second phase: OFF to 4h00min, res. 10 min.
iS3 Insert Probe Set point: (-50 to 50, res. 1°C or 1°F) to stop the third (and last) phase: when the
temperature measured by the three insert probes reaches this value the third phase is ended.
rS3 Room probe Set point: (-50 to 50, res. 1°C or 1°F) for the third (and last) phase: it prevents
temperature from reaching a too low value during the third (and last) phase.
Pd3 Maximum time for the third phase: OFF to 4h00min, res. 10 min.
dbH Defrost before the hold phase: n; Y.
HdS Set point of the holding phase: (-50 to 50, res. 1°C or 1°F) with "OFF" the hold phase is disabled.
IMPORTANT NOTE: If the duration time of a phase is set at the OFF value, the corresponding phase is
disabled. For example, if Pd3=OFF the third phase of the cycle is not active.
11.2 HOW TO USE THE INSERT PROBES
By means the insert probe, the internal temperature of products can be checked. This measure is used to
end the various phase of the cycle. A special internal function detect if the inset probe is not used, in this
case the cycle is made by time.
