○ In particular, each alarm memorises:
•
date and time of intervention;
•
alarm code and description;
•
in/out water temperature values as soon as the alarm was triggered;
•
alarm delay time from the switch-on of the connected device;
•
compressor status at the time of the alarm;
○ Advanced functions:
•
set-up for serial connection (KRS485, KFTT10, KBE, KBM, KUSB
accessory);
•
possibility to have a digital input for remote management of
double set point (DSP);
•
possibility of having a digital input to manage total recovery
(RC100), the desuperheater (DS) or for production of domestic hot
water by means of the 3-way diverter valve (VDEV). In this case, there
is the possibility of using a temperature probe instead of the discrete
input (see specific section for more information);
•
possibility to have an analogue input for the shifting Set-point
(CS) via a 4-20mA remote signal;
•
configured to manage time slots and work parameters with the
possibility of daily/weekly operation planning;
•
check-up and monitoring of scheduled maintenance status;
•
computer-assisted unit testing;
•
self-diagnosis with continuous monitoring of the unit functioning
status.
○ Set-point regulation via the AdaptiveFunction Plus with two options:
•
fixed set-point (Precision option);
•
set-point sliding (Economy option).
•
Compressor drive control serial connection to the programmable
electronic board.
