the electrical circuit that powers the unit; of the alarms on the display;
of operation of the chiller or heat pump by means of display (THAETY-
THAESY-THAEQY);
•
user interface menu;
•
automatic pump operating time balance (DP1-DP2, ASDP1-
ASDP2, DPR1-DPR2 set ups);
•
automatic activation of standby pump in the event of an alarm
(DP1-DP2, ASDP1- ASDP2, DPR1-DPR2 installations);
•
recovery unit/desuperheater water intake temperature;
•
alarm code and description;
•
alarms log management (menu protected by manufacturer password).
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 trig-
gered;
•
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;
Advanced functions:
•
Hi-Pressure Prevent function with forced cooling capacity partiali-
sation for a high outdoor temperature (in summer mode);
•
set up for serial connection (SS, FTT10, KBE, KBM, KUSB acces-
sory);
•
possibility of having a discrete input for double set-point remote
management (DSP);
•
possibility of having a discrete input for total recovery management
(RC100), the desuperheater (DS) or for the production of domestic hot
water by means of a 3-way diverter valve (VDEV). In this case, there
is the possibility of using a temperature probe instead of the discrete
•
possibility of having an analogue input for the shifting set-point via
a 4-20mA remote signal (CS);
•
management of time bands and operating parameters with the
possibility of daily/weekly operating programs;
