6.8 Thawing
The thawing cycle is only available if the load managed by the K4 output is the thawing heater (u1 = 2).
Access the SPECIAL CYCLES menu from the key and select THAWING: at this point the start screen is
displayed, from which you can select the quantity of the product to be thawed using the and keys. The
next time that the key is pressed the cycle starts.
The defrosting cycle is managed on the basis of the amount of product to be defrosted that is loaded into the unit in
relation to the maximum quantity specified by the manufacturer. To keep it simple, the load quantities that can be
selected are divided into three bands, for each of which the controller will load three different sets of predefined
parameters, in accordance with the following scheme:
Load band Initial cabinet setpoint Final cabinet setpoint Cycle duration
LIGHT LOAD r25 r28 r32
MEDIUM LOAD r26 r29 r33
FULL LOAD r27 r30 r34
These three parameters will be used to control the working cabinet setpoints and the duration of the thawing cycle,
equally divided into five phases following on from each other as shown.
- Phase 1 working setpoint = initial setpoint
- Phase 2 working setpoint = phase 1 setpoint + [(initial setpoint – final setpoint) / 4]
- Phase 3 working setpoint = phase 2 setpoint + [(initial setpoint – final setpoint) / 4]
- Phase 4 working setpoint = phase 3 setpoint + [(initial setpoint – final setpoint) / 4]
- Phase 5 working setpoint = final setpoint
