The programming level is for setting the regulatory parameters.
Access to this level is more complex in order to avoid accidental
resetting of the values by the end user.
Switching to programming level:
!
Press button
Arrow UP

Arrow DOWN
simultaneously
for approx. 5 seconds.The first parameter [C1] appears in
the display.

the parameter you want to adjust.
Meaning of parameters
Parameter C1: Target temperature for T1
Parameter C2: Target temperature for T2
The target temperature is the temperature at which the corre-
sponding relay contact is to be activated.
Parameter C10: Hysteresis for target temp. 1
Parameter C11: Hysteresis for target temp. 2
The hysteresis determines how much the milk temperature may
deviate from the target temperature before the cooling com-
pressor is switched on. See sketch.
Parameter C20: Duration of afterstirring
Duration (sec.) for which the stirrer runs after the compressor
has switched off.
Parameter C21: Duration of pause
Duration (min.) until the stirrer is switched back on after being
turned off.
Parameter C50: Duration of SHORT intermittent stirring
Duration (min.) of stirring after short pressing of the "intermittent
stirring" button.
Parameter C51: Duration of LONG intermittent stirring
Duration (min.) of stirring after longer pressing of the "intermit-
tent stirring" button.
Parameter C91: Sensor correction
The sensor reading can be provided with a corrector which
works cumulatively over the entire measurement range.
See also the section on "sensor installation" Page 14.
Parameter C99: Button lock
Alteration of the target temperatures in the working level can be
blocked by setting the button lock.
0 = lock off
1 = lock on.
