• alarm code and description

• management of alarms log.

o In particular, for every alarm, the following are memorised:

• date and time of intervention;

• in/out water temperature values as soon as the alarm was triggered;

• the evaporation and condensation pressure values at the time of the alarm;

• alarm delay from when the connected device is switched on;

• compressor status at the time of the alarm;

o Advanced functions:

• Pump Energy-Saving management;

• evaporator pump control KPE, contactor recovery pump command KPR and KPDS desuperheater Pump Control in the case of external supply of electric

pumps (to be installed by the installer). For the unit to operate properly, activation of the recovery pump, by the installer, must be controlled by means of a

specific discrete output provided in the board on the unit;

• High-Pressure Prevent function with forced cooling capacity partialisation for a high outdoor temperature (in summer mode);

• the EEO - Energy Efficiency Optimizer function allows unit efficiency to be optimised by acting on the electrical absorption, thereby minimising consump-

tion. The algorithm identifies the optimal point that minimises the total absorbed power (compressors+fans) of the unit by actuating the fan rotation speed.

The function allows for an increase in seasonal efficiency of up to 4% if the unit is equipped with the FIEC condensing control accessory with EC fans.

• VPF_R control: (Variable Primary Flow in the main exchanger). VPF_R includes the temperature probs, the inverter management and the management

software of the chiller;

• set-up for serial connection (SS/KRS485, FTT10/KFTT10, BE/KBE, BM/KBM, KUSB accessory);

• possibility to have a digital input for remote management of double set point (DSP);

• possibility of having a digital input for the production of domestic hot water by means of a 3-way diverter valve (CACS contact). In this case, there is the

possibility of using a temperature probe instead of the discrete input. (refer to the specific section for more details);

• option of having domestic hot water diverter valve (VACS) control;

• possibility to have an analogue input for the shifting Set-point (CS) via a 4-20mA remote signal;

• management of time bands and operation parameters with the possibility of daily/weekly functioning programs;

• check-up and monitoring of scheduled maintenance status;

• computer-assisted unit testing;

• self-diagnosis with continuous monitoring of the unit functioning status.

• MASTER/SLAVE management logic integrated in single systems (SIR - Sequenziatore Integrato - Integrated Sequencer) -Refer to the specific section for

more details

o Set-point regulation via the AdaptiveFunction Plus with two options:

• fixed set-point (Precision option);

• set-point sliding (Economy option).
