Please contact Your tax office or utility. WBAN (R-407C) Size Heating [kw] 41 14,9 61 19,3 81 26,3 REPLACE: BT05I016GB-09 The heating of the future respects the environment. The VULCAN heat pump series represent an important stage in the development of this type of unit. They feature the most up-to-date advances in technology, standing out for: EFFICIENCY thanks to its special construction, the WBAN series ensures high energy efficiency also in extreme working conditions; SELF-ADAPTING the evolved electronics implemented adapt the operating parameters of the chiller to the load conditions of the system it is installed in, optimising consumption, noise and the working life of the components; EASE OF INSTALLATION each unit is supplied as standard with a complete hydronic assembly and is completely tested in the factory; installation is consequently quick and easy. CERTIFIED QUALITY SYSTEM UNI EN ISO 9001:2008 According to the UNI EN 14511:2008

PERFECT FOR RESIDENTIAL EUROVENT ENERGY EFFICIENCY CLASSIFICATON CLASS A IN HEATING MODE PERFECT FOR HEATING AND UNDERFLOOR HEATING Thanks to its characteristics the unit can be used both in traditional systems with TERMINAL UNITS and in systems with EMBEDDED UNDERFLOOR PIPING with higher efficiency than traditional units. TOP NOISELESSNESS FOR A SUPERIOR COMFORT EUROVENT ENERGY EFFICIENCY CLASSES WATER: 30/35 C AIR 7 C D.B. / 6 C W.B. Noise is one of the most critical factors of this type of unit. The application of special regulation logic enables to adapt the fan operating speed to the system load and to the external air temperature. In this way you can optimize the energy efficiency and guarantee the lowest possible noise level, especially during evening and night hours, when the air temperature is lower and sensitivity to noise is greater. WATER FILTER - SUPPLIED AS STANDARD (external installation) Steel mesh mechanical filter positioned at the exchanger inlet. Suitable for filtering water and trapping the impurities present in the water circuit. ICE PROTECTION SYSTEM A special measure in the refrigerating circuit prevents ice from forming in the base of the air exchanger. STANDARD-SUPPLIED USER KEYPAD The remote keyboard allows unit start and stop, Summer/Winter setting, 2 selections of ambient temperature, one of "COMFORT" temperature where the set point is visualized only on board, an other of "ECO" temperature that decreases in winter mode and increases in summer mode the set point and the hidric /cooling/electric circuit alarm signal. The connection is done with a shielded cable 3 x 0.34mm2 max 100m which is connected with the unit. Thanks to its pleasant aspect it can be installed in ambient.

SFSTR4N - Disposal for inrush current reduction HYDRONIC Disposal for inrush current reduction, for unit 400/3/50+N Starting up a motor directly can overload the electricity network, with start-up currents up to 8 times the nominal current. Thanks to the breakaway current reduction device, start-up takes place gradually, with the start-up current being limited during this period of time. The start-up current can therefore be reduced to 3.5-4 times the nominal current, meaning that the power systems and protection devices can be sized with lower parameters. In sizes 41 230/1/50, the soft starter is included standard. Configuration Detail PBLC1X - Service handset for local control with 1.5-metre cable The service keyboard is necessary for the unit programming and setting. These operations must be done by qualified personnel without compromising the operation of the whole unit. The service keyboard is supplied with a connection cable of 1,5 m lenght. CMMBX - Serial communication module to supervisor (MODBUS) The serial communication module to supervisor (MODBUS) is connected with the principal module through a comb connection (see lay-out on electrical panel). In this way the remote assistance and supervision are available through standard MODBUS protocol. It is possible to connect to a single supervisor system up to 127 units. The connection to PC must be obtained through a converter RS485/232; the serial port RS232 admits as maximum a 10 m length. The serial communication module to supervisor (MODBUS) is necessary when the unit is connected to ELFOCONTROL. AMRX - Rubber antivibration mounts The rubber antivibration mounts reduce the vibrations of compressor during its operation and they are installed at the base toe. 11

SYSTEM ACCESSORIES KTFL1X - Hose kit for connection to chiller/heat pump. With connections of 1" The kit is composed of: Two hoses, length 300 and diameter 1, required for connection of the machine to the system. This kit can be used for heat pumps from 4 to 18kW KTFL2X - Hose kit for connection to chiller/heat pump. With connections of 1 1/4" The kit is composed of: Two hoses, length 300 and diameter 1 ¼, required for connection of the machine to the system. This kit can be used for heat pumps from 19 to 30kW KBQRE5X - 500 litres domestic hot water kit The kit is composed of: - Storage tank in Fe360b and internal vitrification treatment in accordance with DIN 4753.3, external insulation in stiff polyurethane and exchange coil xx m2, maximum operating pressure 6 bar - Electrical heating element 4 kw for possible integration and anti-legionellosis cycle for boiler of 500 litres. - Electronic module for the management of the production of domestic hot water: DHW temperature setting, setting of time period for production of domestic hot water with priority based on a minimum temperature, management of anti-legionellosis cycle, control for three-way valve, management of the electrical heating element. The electronic module dialogues with the heat pump through the serial communication cable. - Three-way deviator valve 1 1/4 and non-return valve 1 1/4 to be installed in the system - Serial connection cable twisted and shielded for networks RS485 AGW22/24 with a length of 15 metres. - Serial communication card CMMBX to be connected in the heat pump Dimensions of boiler of 500 litres: 760 x 1690mm If this accessory is requested, the unit cannot be provided with the three-way valve installed on board. This is because it is to be installed on the system, near the hot water heater. KITERAX - Room thermostat Wall-mounted weekly electronic timer thermostat with summer, winter night adjustment. Range of adjustment +2 C/+35 C. Dimensions 123X88X23 mm. 12

KVMSP1X - Radiant panels management kit with 1" connections KVMSP2X - Kit for management of radiant panels with connections of 1 1/4" (KVMSP1X)The kit is made up of: 1 Mixer valve with three-point modulating actuator. Power box and modulating valve connection Temperature probe to be installed on the outlet of the radiator panels (l=20metres) Thermostat of maximum temperature 55 C Control for circulation pump to the radiator panel This kit may be used with 4-18kW heat pumps (KVMSP2X)The kit is made up of: 1 1/4 Mixer valve with three-point modulating actuator. Power box and modulating valve connection Temperature probe to be installed on the outlet of the radiator panels (l=20metres) Thermostat of maximum temperature 55 C Control for circulation pump to the radiator panel This kit may be used with 19-30kW heat pumps KVICX - Boiler control kit The kit is composed of: -Pair of two way motorized valves for boiler cut-off -Pair of two way motorized valves for heat pump cut-off Valve control electrical junction box KSAX - 100 litres hydraulic breaker Storage tank Fe360b and anti-corrosion treatment with organic enamelling, external insulation with polyurethane and polyethylene mat, thickness 50 mm maximum of operation 6 bar. Diameter 500 Height 900 N 8 connections CACSX - Domestic hot water kit control The module makes it possible to control the temperature of a domestic hot water tank, not provided by Clivet. The adjustment module comes with 2 temperature probes, 1 safety thermostat, power circuit and heating element control with protections against short circuits (the heating element is not provided by Clivet) and the installation box. As opposed to the control of domestic hot water performed directly by the machine electronics, the kit makes it possible to set re-fill time periods and anti-legionella cycles, and to manage a re-circulation pump on the storage tank. The storage tank must be suitably sized based on the combination with the selected heat pump. 13
