5 Illuminated When in program Pr2 indicates the parameter is also present in
Program function and operation.
Each of the programs is divided into 3 phases of operation.
Phase 1: Hard Chill.
Phase 2: Soft Chill.
Phase 3: Freezing Cycle.
For each phase there are 3 parameters.
IS1 (iS2, iS3): operation controlled by the Food Probe.
RS1 (rS2, rS3): set point for the room Temperature Probe for each phase.
Pd1 (Pd2, Pd3): The maximum time duration for each phase.
Hds: hold phase set point at the end of the whole cycle.
There are also 2 parameters relating to defrost.
These are dbC = Defrost Before cycle, dbH = defrost before hold (at the end of the cycle).
Cycle Parameter Definitions.
Parameter Range Minimum Description
dbc: yes/ no ------------ Defrost before cycle
First Phase
iS1
50 to + 50°C 1°C or 1°F Food Probe Set Point (when the temperature
measured by the food probe reaches this value
the first phase is ended).
rS1 50 to + 50°C 1°C or 1°F Air Temperature Set Point (prevents the air
temperature going to low during the first phase).
Pd1 OFF to 4.0 hours 10 minutes Maximum Time For The First Phase
Second Phase
iS2
50 to + 50°C 1°C or 1°F Food Probe Set Point (when the temperature
measured by the food probe reaches this value
the second phase is ended).
rS2 50 to + 50°C 1°C or 1°F Air Temperature Set Point (prevents the air
temperature going to low during the first phase).
Pd2 OFF to 4.0 hours 10 minutes Maximum Time For The Second Phase
Third Phase
iS3
50 to + 50°C 1°C or 1°F Food Probe Set Point (when the temperature
measured by the food probe reaches this value
the whole cycle is ended).
rS2 50 to + 50°C 1°C or 1°F Air Temperature Set Point (prevents the air
temperature going to low during the third
phase).
Pd3 OFF to 4.0 hours 10 minutes Maximum Time For The Third Phase.
dbH yes/ no ------------ Defrost before the hold phase
HdS 50 to + 50°C or OFF 1°C or 1°F Set Point OF The Hold Phase. If set to OFF the
hold Phase is disabled.
Important Note: If the duration time phase is set to OFF the corresponding phase is disabled.
E.G. If Pd3 = OFF the third phase of the cycle is not active.
Cycle Parameter Access
To access the cycle parameters Press and Hold the Set and Down buttons for 2 seconds.
The display will show “Prb” press the down button and scroll through until you get to “FCY” cycle management.
Press Set “Cy1” will be displayed, press the down button to scroll through the submenu to select the required
cycle parameters. Once selected press the set key to access the cycle parameters.
QC 11 Cycle Parameters.
Soft Chill- for the safe chilling of delicate products. (Cy1)
dbC = no iS1 = -10°C iS2 = 5°C iS3 = 3°C dbH = no
rS1 = 2°C rS2 = -2°C rS3 = -2°C HdS = 3°C
Pd1 = 1.3 hours Pd2 = OFF Pd3 = OFF
