“ENERGY SAVING” FUNCTION

8.1

Preliminary notes

Once the time you have set with parameter i10 has passed,

without activations of the door micro switch input (after the

room temperature has reached the work set point) the

“energy saving” function is activated (until the input is

activated again).

During the “energy saving” function, the work set point is

increased by the temperature established with parameter r4

and the evaporator fan is turned on cyclically, provided that

the F0 parameter is set to 1, 2, 3 or 4 (parameter F13

establishes the duration of fan switch off and parameter F14

that of switch on).

It is also possible to activate the “energy saving” function in

remote mode through the digital inputs (with effect only on

the compressor).

“CPT” FUNCTION (CALCULAT-

ED PRODUCT TEMPERATURE)

9.1

Preliminary notes

If parameter P4 is set at 4, the temperature associated to the

regulation will mainly depend on the temperature detected by

the inlet air probe and that detected by the air outlet probe,

herein

called

CPT

temperature

(Calculated

Product

Temperature); the room temperature probe shall operate as

an air inlet temperature probe and the auxiliary temperature

probe as an air outlet temperature probe.

The formula for the calculation of the CPT temperature is:

CPT temperature = {[(value established with parameter P7) x

(temperature detected by the inlet air probe)] : 100} +

{[(100 - value established with parameter P7) x (temperature

detected by the outlet air probe)] : 100}.

“HACCP” FUNCTION

10.1

Preliminary notes

The device can memorise the following HACCP alarms:

minimum temperature alarm (code “AL”)

maximum temperature alarm (code “AH”)

door micro switch input alarm (code “id”)

power supply cut-off alarm (code “PF”; only in the

models with clock).

The device can memorise up to 9 alarms, after which the

oldest alarm is overwritten.

The device supplies the following information for every alarm:

the critical value

the date and time at which the alarm occurs (only

in the models with clock)

the duration of the alarm (from 1 min to 99 hours

and 59 min, partial if the alarm is in progress).

The following table shows the correspondence between the

alarm codes and the relevant critical values.
