Adjustments must be made so that the condition b1<b2 is always met. The values of parameters b1 and b2
they are not control temperature settings; these are the temperature values between which the control
temperature can be set (a section from the entire control temperature range of the controller).

This function is active only when the minimum standstill time of the unit has been set (CF parameter).

Changing the parameter value is not recommended, because it can lead to incorrect operation of the
controller, and even its damage.

3.4.2. Unit control function.
The unit is controlled in the cooling phase depending on the temperature in the cooling
chamber. The controller allows one or two settings to be controlled, depending on the
FC parameter settings (milk pre-cooling time – see section 3.4.1. Table of settings for the
cooling segment):
FC=0 – no pre-cooling. In this case, the settings made in parameter t1 (see section
3.5. Table of setting for the cooling segment available to the user) are the only
temperature for cooling the milk; the cooling signal diode is permanently on.
FC>0 – during the time set in this parameter, initial cooling takes place according to
the settings made in parameter t1; during the initial cooling the cooling signal diode
blinks. After the time set in the FC parameter has elapsed, the transition takes place
for cooling according to the temperature set in parameter t2; the cooling signal
diode is permanently on.
At any time, you can interrupt the initial cooling and go for cooling according to the
target temperature. This is done by pressing the button
during pre-cooling;
the signal diode starts to changes its lighting to continuous.
The controller can control the cooling temperature in the range from -40
O
C to +98
O
C.
In order to limit the scope of the control so as to prevent the user of the cooling device
from setting the temperature outside this range, set the appropriate parameters in the
appropriate ranges: b1 – limiting the lower value for the control temperature range and
b2 – limiting the upper value for the control temperature range.
It is also important to set the control hysteresis correctly – parameter HI. The control
hysteresis determines the temperature difference at which the compressor is switched
off and then on, e.g. if the control temperature is set as 4
O
C, and the hysteresis on 2
O
C,
the compressor will stop after reaching 4
O
C, and its re-activation will occur after
the temperature increases to 4 + 2 = 6
O
C.
The controller allows setting the control hysteresis in the range from 1
O
C to 20
O
C.
