SECTION II: INSTALLATION ANDMAINTENANCE
oThe following is memorised for each alarm:
date and time of intervention (if the KSC accessory ispresent);
in/out water temperature values as soon as the alarm istriggered;
the 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;
oAdvanced functions:
Hi-Pressure Prevent function with forced cooling capacity
partialisation for a high outdoor temperature (in summermode),
set-up for serial connection (KRS485, KFTT10, KRS232, KUSB
accessory);
possibility to have a digital input for remote management of the
double Set point (see the Pre-sales Department);
possibility to have an analogue input for the shifting Set-point via a
4-20mA remote signal (contact Pre-sales Department);
set-up for management of time bands and operating parameters with
the possibility of daily/weekly operating programs (KSC accessory);
check-up and verification of the scheduled maintenancestatus;
computer-assisted machine testing;
self-diagnosis with continuous monitoring of the machine operating
status.

RC100), prevents the risk of ice formation inside the recovery unit
exchanger when the machine is switched off (provided the unit remains
powered).
RAS –300W storage tank anti-freeze resistance (available for ASP1-
ASDP1- ASP2-ASDP2 set-ups); prevents the risk of ice formation inside
the exchanger tank when the machine is switched off (provided the unit
remains powered).
RAE 1 –27W electric pump anti-freeze resistance (available for P1-
DP1-ASP1-ASDP1 set-ups); prevents the risk of the water inside the
pump becoming ice when the machine is switched off (provided the unit
remains powered).
RAE 2 –27W double electric pump anti-freeze resistance (available for
P2-DP2-ASP2-ASDP2 set-ups); prevents the risk of the water inside the
pumps becoming ice when the machine is switched off (provided the
unit remains powered).

accessory).
BT –low temperature of water produced (only for models 270÷2160).
CS –4-20 mA analogue signal for shifting Set-point (incompatible with
the DSP accessory). The EEV accessory may have to be also installed,
depending on the required values.
RPB –Coil protection mesh with accident-prevention function.
IMB –Protective packaging.
