Outputs and Buzzer Configuration

The instrument outputs can be configured by the relative pa-
rameters 

o.o1

 , 

o.o2

 and 

o.o3

.  The outputs can be configured 

for the following functions:

r1

 

To control the temperature control device of 

loop 1

;

r2

 

To control the temperature control device of 

loop 2

;

dF

 

To control the defrost device;

Fn

 

To manage the recirculation fans;

Au

 

To control the auxiliary device (see the Auxiliary output 
functioning);

At

 

To control a silenceable alarm device through a con-
tact that is normally open and closed when in alarm;

AL

 

To control an alarm that cannot be silenced through a 
contact that is normally open and closed when in alarm;

-t

 

To control a silenceable alarm device through a contact 
that is normally closed, and then open when in alarm;

-L

 

To control an alarm that cannot be silenced through a 
contact that is normally closed and open when in alarm;

on

 

Output ON when the instrument is in ON state.  This 
mode can be used to control lights, non-misting resist-
ance ON room door or other utilities;

oF

 

No function (output disabled).

If an outoput is configured as 

Aux

 (

o.o1

o.o2

o.o3

 = 

Au

), its 

function is defined by the parameter 

o.Fo

 and conditioned by 

the time set with parameter 

o.tu

o.Fo

 can be configured for the following functions:

oF

 No function (Auxiliary output not active);

1. 

Delayed from 

r1

 control output.  The auxiliary output is 

activated with the 

o.tu

 delay after the activation of the 

output configured as 

r1

.  The output is then turned OFF 

at the same time of the 

r1

 output.  This mode can be 

used as a command for a second compressor or for all 
those working utilities operating as the 

r1

 output, but 

which must be delayed after the compressor start up to 
avoid excess electricity absorption.

2. 

Delayed from 

r2

 control output.  Similar to mode 1 func-

tioning mode but referred to 

r2

.

3. 

Activation by the key  ,   or   or by digital input with 
contact NO: the output is activated pressing a key  , 
,   suitably configured with 

t.UF

t.fa

 or 

t.Fb

 = 

1

 or via 

the digital input (

i.Fi

 = 

4

).  These commands have a tog-

gle (bi-stable) function (the 1

st

 key pressure activates the 

output while the 2

nd

 disables the output).  In this functioning 

mode, the 

Aux

 output can be turned OFF automatically 

after a certain time that can be set with the parameter 

o.tu

.  

With 

o.tu

 = 

oF

 the output is activated and deactivated only 

manually, using a key ( ,  ,  ) or the digital input.  Dif-
ferently, the output, once activated, is turned OFF auto-
matically after the 

o.tu

 time.  This mode of operation can 

be used to control the shop window lighting, anti-fogging 
resistors or other utilities.

4. 

Internal Light output managed by digital input.  The output 
will be ON when door is opened (

i.Fi

5

6

).

The internal buzzer (when present) can be configured by 
parameter 

o.bu

 to carry out the following functions:

oF

  Buzzer always disabled;

The Buzzer sounds when an alarm is active;

The Buzzer sounds when a key pressed (does not signal 
alarms);

The Buzzer sounds when a key pressed and when an 
alarm is active.

5.5 

Temperature Controllers

The type of control of both the loops is ON/OFF and acts 
on the outputs configured as 

r1

 and 

r2

 depending on: the 

probes measure (

Pr1,

 

r2

), the Set Points (

SP

SP2

), the dif-

ferentials (hysteresis) 

r.d1

r.d2

 and the action 

r.Fc

.

By appropriately configuring the instrument, it is possible to 
obtain a neutral zone controller, 2 independent controllers 
in cooling mode, 2 independent controllers in heating mode 
or two independent controllers: one in cooling mode and the 
other in heating mode.
Depending on the function mode programmed with param-
eter 

rfC

 the relative differentials 

r.d1

 and 

r.d2

 are automati-

cally considered by the controller with 

positive

 values for 

Cooling

 actions (

r.fC

 = 

C

) or with 

negative

 values for 

Heat-

ing

 actions (

r.fC

 = 

H

).

The 

r1

 controller always has 

Pr1

 measurement as process 

value while the 

r2

 controller can use, as process value, the 

measurement of 

Pr1

Pr2

 or 

Pr3

 probes depending on the 

value programmed at parameters 

i.P2

 and 

i.P3

.

If one of 

i.P2

/

i.P3

 parameters is configured with a value 

different than 

r2

, the process value of 

r2

 controller is always 

the 

Pr1

 probe measure.  If instead 

i.P2

 or 

i.P3

 is configured 

r2

 the probe to which the parameter refers will be consid-

ered as process value for the 

r2

 controller.

When the neutral zone operating mode is selected, the pro-
cess value considered by the controller is only the 

Pr1

 probe 

measurement (even if a probe is configured for 

r2

 operation).

Similarly, the Set Point value for the neutral zone operating 
mode is always 

SP1

 while in all other cases, the 

r1

 controller 

always have 

SP1

 as the Set Point value while the 

r2

 control-

ler always have 

SP2

 (remember that 

SP2

 can still be pro-

grammed as relative to 

SP1

 through the parameter 

S.Sc

 = 

2r

).

Through parameter 

r.Fc

 it is possible to select the operating 

mode of the two controllers in the following ways:

Neutral zone controller (Single Loop) - 

r.Fc

 = nr

In neutral zone operation (double action ON/OFF control) it is 
possible to control the temperature of a system equipped with 
both a cooling element (to be connected to the output con-
figured as 

r1

) and a heating element (to be connected to the 

output configured as 

r2

), based on a single Set Point (

SP1

).

The controller behaves as follows: it switches OFF the ac-
tive output when 

Pr1

 process value reaches the 

SP1

 Set 

Point and activates the 

r1

 output when the 

Pr1

 temperature 

is greater than [

SP1

 + 

r.d1

], or it switches on the 

r2

 output 

when the process value is less than [

SP1

 - 

r.d2

].
