UNIT DESCRIPTION

II.1.1

CONSTRUCTION FEATURES

 Patented polyvalent system.
 Load-bearing structure in galvanised and RAL 9018 painted sheet
steel, coated on the inside with sound-absorbing material, divided into:
 soundproofed technical compartment for housing the compressors,
the electrical board and the main components in the refrigerant circuit.
 Aeraulic compartment for housing the heat exchange coils, the
motor-driven fans and the pump assembly accessory if present.
 Hermetic, Scroll-type rotary compressors, complete with internal
thermal protection and crankcase heater activated automatically when
the unit stops (as long as the power supply to the unit is preserved).
 Double electric axial fan with external rotor, equipped with internal
thermal protection and complete with protection grille.
 Proportional electronic device for the pressurised and continuous
regulation of the fan rotation speed down to an external air temperature
of -10°C when operating as a chiller and up to an external air
temperature of 40°C when operating as a heat pump.
 Stainless steel plate heat exchangers on the primary and secondary
water circuits, complete with closed cell polyurethane foam rubber
insulation and antifreeze electric heaters.
 Differential pressure switch on all heat exchangers.
 Air side exchanger comprised of a copper pipe coil flared into
aluminium fins with "corrugated" design in order to increase heat
exchange efficiency.
 Male threaded water connections.
 Refrigerant circuit realised with annealed copper piping (EN 12735-
1-2) and welded with silver alloy. Complete with 2 cycle inversion
valves, charge connections, high and low pressure switch, 2
thermostatic valves, 4 solenoid valves, a drier filter, 2 liquid receivers, a
gas separate, a humidity indicator, 3 non-return valves and a safety
valve (for models 130).
 Primary and secondary water circuit made from annealed copper
piping (EN 12735-1-2) and welded with silver alloy. The primary water
circuit also comes complete with:
pump, safety valve (3 bar), pressure gauge, expansion tank, manual
bleed valves and drainage valves.
 Secondary water circuit made from annealed copper piping (EN
12735-1-2) and welded with silver alloy, complete with differential
pressure switch.
 Compatible control with AdaptiveFunction on the primary
circuit regulation.
 Unit with IP24 level of protection.
 The unit is complete with the R410A refrigerant charge.

ELECTRICAL BOARD FEATURES

 Electrical board accessible by opening the front panel, conforming
with current IEC standards, and which can be opened and closed with a
suitable tool.
 Complete with:
 electrical wiring arranged for power supply 400V-3ph+N-50Hz
 auxiliary power supply 230V-1ph-50Hz drawn from the main power
supply;
 general isolator, complete with door interlocking isolator;

 Programmable electronic board with microprocessor, controlled by
the keypad inserted in the machine.
 This electronic board performs the following functions:
 regulation and management of the set points for inlet water
temperature; cycle inversion; safety timer delays; circulating pump;
compressor and system pump hour-run meter; of pressure defrost
cycles; electronic anti-freeze protection which cuts in automatically
when the machine is switched off; and the functions which control the
operation of the individual parts making up the machine;
 complete protection of the unit, automatic emergency shutdown and
display of the alarms which have been activated;
 compressor protection phase sequence monitor
 unit protection against low or high phase power supply voltage;
 visual indication of the programmed set points via the display; of the
in/out water temperature via the display; of the alarms via the display;
and of cooling/heat-pump operating mode via display;
 self-diagnosis with continuous monitoring of the functioning of the unit;
 user interface menu;
 alarm code and description;
 alarm history management (menu protected by manufacturer
password).
 The following is memorised for each alarm:
 date and time of intervention (if the KSC accessory is present);
 alarm code and description;
 inlet/outlet water temperatures when the alarm intervened;
 alarm delay time from the switch-on of the connected device;
 compressor status at moment of alarm;
 Advanced functions:
 configured for serial connection (KR S485, KFTT10, KBE, KBM,
KUSB accessory);
 possibility to have a digital input for remote management of the
double set point (contact HITECSA
 possibility to have an analogue input for the scrolling set-point via a
4-20mA remote signal (contact
 configured for management of time bands and operation parameters
with the possibility of daily/weekly operating programs (KSC accessory);
 check-up and monitoring of scheduled maintenance status;
 testing of the units assisted by computer;
 self-diagnosis with continuous monitoring of the functioning of the unit;
 Adaptive Function on the regulation of the primary circuit.
