 the evaporation and condensation pressure values at the time of the alarm;
 alarm delay time from the switch-on of the connected device;
 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 elec-
tric 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 con-
sumption. The algorithm identifies the optimal point that minimises the total absorbed power (compressors+fans) of the unit by actuating the fan rotation
speed.
 VPF_R control: (Variable Primary Flow by HITECSA 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 discrete input for total recovery management (RC100 contact), the desuperheater (CDS contact) or 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 HITECSA - HITECSA 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).
