20. CELL TEMPERATURE ADJUSTMENT

Refer to the following graphic for the resistance and compressor switching on/off.
Both compressor and resistance activation are always enabled for all phases.

Where:
Setpoint

is the adjustment setup set for the ongoing phase


zmf

is the cold dead zone for the ongoing phase

istf

is the cold adjustment hysteresis (parameter P15)


zmc

is the hot dead zone for the ongoing phase

istc

is the hot adjustment hysteresis (parameter P21)


Never switch on resistances during the stop and preservation phases of an automatic cycle or during the refrigeration
phase of a manual cycle. Resistances must be switched on for a minimum time, determined by parameter P30.

During the awakening and rising phases, the temperature increase is adjusted by dividing the temperature area by n steps
(which are preset by means of parameters P24 and P25) so that the heating will be gradual according to setpoints that are
close to the desired value, as follows:
If the temperature in the cell is 5°C at the awakening start, the setpoint that has been preset for the awakening phase is
25°C, the number of steps is 4 and the duration of the phase is 40 minutes; resistances work for 10 minutes at the 10°C
temperature setpoint, for 10 minutes at the 15°C temperature setpoint, for 10 minutes at the 20°C temperature setpoint
and for the last 10 minutes at the 25°C temperature setpoint.
