SECTION II: INSTALLATION AND MAINTENANCE
o
The following is memorised for each alarm:
date and time of intervention (if the KSC accessory is present);
in/out water temperature values as soon as the alarm is triggered;
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;
o
Advanced functions:
Hi-Pressure Prevent function with forced cooling capacity
partialisation for a high outdoor temperature (in summer mode),
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 maintenance status;
computer-assisted machine testing;
self-diagnosis with continuous monitoring of the machine operating
status.

boards (maximum: 200 units for a max. distance of 1000 m) and the
building automation or external supervision systems.
CR
– Power factor correction capacitors (cosΦ > 0.91).
EEV
– Electronic thermostatic valve.
RAP
– Unit with copper/pre-painted aluminium coils.
BRR
– Unit with copper/copper coils.
DSP
– Double Set-point via digital consensus (incompatible with the CS
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.
